IVF (In-Vitro Fertilization) Treatment

Introduction

In-vitro fertilization (IVF) is a treatment for infertility in which an egg is fertilized by sperm outside the body, in a laboratory, and the resulting embryo is then transferred into the uterus with the goal of establishing a pregnancy. It is one of the most established and widely used forms of assisted reproductive technology, with more than ten million children born worldwide since the first IVF birth in 1978.

People come to IVF in many different situations — after months or years of trying to conceive, after other fertility treatments have not worked, after a diagnosis that makes natural conception unlikely, or as a planned approach for specific medical reasons. The journey can be physically demanding, emotionally taxing, and uncertain. It can also lead to a healthy pregnancy and child — for many people, it is the route through which their family becomes possible.

This article explains what IVF is, who it is generally used for, what a typical IVF cycle involves step by step, what the realistic chances of success are, what risks the treatment carries, and how people manage the emotional and practical side of it. The aim is to help you understand what you are likely to encounter, what questions to ask, and what to expect at each stage. It is not a substitute for the detailed counselling you will have with your fertility specialist, but it gives you a foundation to enter that conversation prepared.

What Is IVF?

IVF stands for in-vitro fertilization. The Latin phrase in vitro means “in glass” — a reference to the laboratory dish in which fertilization takes place, rather than inside the body. The basic idea is straightforward: eggs are collected from the ovaries, sperm is added in the laboratory, fertilization occurs and the resulting embryos develop for several days, and one or more healthy embryos are then placed back into the uterus in the hope of implantation and pregnancy.

What sounds like a single procedure is in reality a sequence of carefully timed steps that unfolds over several weeks. The hormonal medications, monitoring, egg retrieval, fertilization, embryo culture, and embryo transfer together make up what is called an IVF cycle. The full cycle typically takes four to six weeks from the start of medications to the pregnancy test, although the timeline varies between protocols and clinics.

IVF is part of a broader family of assisted reproductive technologies that also includes simpler treatments such as ovulation induction and intrauterine insemination (IUI). IVF is generally not the first treatment offered for infertility — less invasive options are usually considered first when they are likely to work. IVF is considered when other treatments have not succeeded, when the underlying problem makes simpler treatments unlikely to work, or when there is a specific medical reason that IVF is needed.

Who Is IVF For?

IVF is used in a wide range of situations. The decision to recommend IVF rather than another treatment depends on the cause of infertility, the duration of trying to conceive, the woman’s age, what other treatments have been tried, and the couple’s preferences.

Common reasons fertility specialists consider IVF include:

• Tubal factor infertility — blocked, damaged, or absent fallopian tubes mean the egg and sperm cannot meet naturally. IVF bypasses the tubes entirely.
• Severe male factor infertility — very low sperm count, poor motility, or abnormal sperm shape. IVF, particularly with a technique called ICSI (described later), can achieve fertilization when natural conception would be very unlikely.
• Endometriosis — particularly more advanced stages, or after surgery has not led to pregnancy.
• Ovulation disorders — particularly when simpler treatments such as ovulation induction with or without IUI have not worked.
• Unexplained infertility — when standard tests do not identify a cause and other treatments have not succeeded over a reasonable time.
• Diminished ovarian reserve — reduced number of eggs, often suggested by hormone tests or by age.
• Genetic conditions in one or both partners — IVF allows embryos to be tested for specific genetic conditions before transfer, in a process called preimplantation genetic testing (PGT).
• Fertility preservation — freezing eggs or embryos before treatments such as chemotherapy that may affect fertility, or for other medical reasons.
• Recurrent miscarriage — in selected cases, particularly when genetic causes are suspected.

For each of these situations, the decision to use IVF rather than other treatments is made after a fertility evaluation, often including hormone tests, ultrasound, semen analysis, and assessment of the tubes and uterus. Fertility specialists generally consider what is most likely to work, what is least invasive, and what fits the patient’s individual situation.

Alternatives to Consider First

IVF is a substantial undertaking. For many couples experiencing difficulty conceiving, simpler treatments are tried first when there is a reasonable chance they will work. These alternatives include:

• Ovulation induction — medications taken in tablet or injection form to encourage the ovaries to release an egg. Used particularly for women who do not ovulate regularly, such as those with polycystic ovary syndrome (PCOS).
• Intrauterine insemination (IUI) — prepared sperm is placed directly into the uterus around the time of ovulation. Less invasive than IVF and considered by specialists for some couples with unexplained infertility, mild male factor, or certain other situations.
• Surgical treatment of underlying conditions — in some cases, surgery for endometriosis, fibroids, polyps, or tubal disease can restore the chance of natural conception.
• Lifestyle factors — weight optimisation, smoking cessation, alcohol moderation, and management of conditions such as thyroid disorders or diabetes are associated with improved fertility outcomes.

For some situations, however, simpler treatments are unlikely to succeed and IVF is the path doctors recommend without going through them. Examples include severely damaged or absent tubes, very severe male factor, or significant age-related decline in fertility where time is a limiting factor. Your fertility specialist will help you weigh which path is most appropriate for your circumstances.

The IVF Cycle: Step by Step

An IVF cycle is a sequence of carefully timed events over four to six weeks. Different clinics use slightly different protocols, and your own cycle may vary. The general sequence is described below.

1. Pre-cycle preparation and counselling

Before the cycle begins, you and your partner will have detailed consultations with the fertility team. These typically include:

• Review of your medical history, prior pregnancies, and prior fertility treatments
• Investigations — blood tests, hormone profiles, ultrasound of the ovaries and uterus, semen analysis
• Screening for infections (such as hepatitis B, hepatitis C, HIV, rubella status)
• Counselling about the treatment plan, success rates, risks, and what to expect
• Counselling about decisions you will face during the cycle — how many embryos to transfer, what to do with any additional embryos, whether to use additional techniques such as ICSI or PGT
• Practical planning — medications, scheduling, time off work, and emotional preparation

This is the time to ask everything. The IVF team will provide a written plan and contact details for questions during the cycle.

2. Ovarian stimulation

In a natural menstrual cycle, the ovary typically releases one mature egg. IVF aims to produce several mature eggs in a single cycle, to increase the chance of obtaining good-quality embryos. This is done with hormonal medications, typically given by injection, over about 10 to 14 days.

The medications stimulate the ovaries to develop multiple follicles, each of which may contain an egg. Different stimulation protocols exist — the choice depends on factors such as your age, ovarian reserve, response to previous cycles, and the clinic’s approach. Most women self-administer the injections at home after being taught how to do so.

3. Monitoring

During stimulation, you will have several visits to the clinic for ultrasound scans and blood tests, usually every two to four days. The scans show how the follicles are developing in size, and the blood tests measure hormone levels. Based on these results, the medication dose may be adjusted up or down. The aim is to obtain enough mature follicles without over-stimulating the ovaries.

4. Trigger and egg retrieval

When the follicles have reached the right size, a final “trigger” injection is given at a precise time. This causes the eggs to undergo final maturation. Egg retrieval is then scheduled about 34 to 36 hours after the trigger, before the eggs would naturally be released.

Egg retrieval is a short procedure, usually performed under sedation. A thin needle is passed through the vaginal wall under ultrasound guidance into each follicle, and the fluid (containing the egg) is gently aspirated. The procedure typically takes 20 to 30 minutes. Most women rest for an hour or two afterward and can go home the same day. Mild cramping and spotting for a day or two are common.

The retrieved eggs are taken immediately to the embryology laboratory, where they are examined and prepared for fertilization.

5. Fertilization in the laboratory

On the same day as egg retrieval, the eggs are combined with sperm in the laboratory. There are two main methods:

• Conventional IVF — prepared sperm is placed in a dish with each egg, and fertilization occurs naturally. Used when sperm quality is normal.
• Intracytoplasmic sperm injection (ICSI) — a single sperm is injected directly into each mature egg using a fine needle. Used when sperm quality is reduced, when previous IVF attempts have had fertilization problems, or in certain other situations.

The eggs are then incubated and checked for signs of fertilization the next morning. Not every egg will fertilize; this is normal and expected.

6. Embryo culture and blastocyst development

Fertilized eggs (now embryos) develop in the laboratory under carefully controlled conditions. Embryologists check on their development each day. Most embryos are cultured for three to five days, although some clinics culture for longer.

An embryo grown to day five or six is called a blastocyst. Blastocyst culture allows the embryologist to select embryos that have developed well past the early divisions, which may correlate with a higher chance of implantation. Not every embryo reaches blastocyst stage — some stop developing earlier — but those that do represent the embryos most likely to be viable.

Decisions about whether to transfer at day three (cleavage stage) or day five (blastocyst stage) depend on the number of embryos developing, the quality at each stage, the patient’s history, and the clinic’s practice. Blastocyst culture is now standard practice in many centres.

7. Embryo selection and genetic testing (PGT)

If there are several embryos, the team selects which one (or sometimes more) to transfer. Selection is based on visual assessment of embryo quality and development.

In some cases, embryos are tested for genetic conditions before transfer in a process called preimplantation genetic testing:

• PGT-A (for aneuploidy) checks for abnormal numbers of chromosomes — the most common cause of miscarriage and implantation failure, particularly in older women.
• PGT-M (for monogenic disease) is used when one or both parents carry a specific genetic condition and want to avoid passing it on.
• PGT-SR (for structural rearrangements) is used when a parent has a known chromosomal structural problem.

PGT requires a biopsy of a few cells from each embryo, which is then tested. This adds time, because embryos are typically frozen while results come back, and it is not appropriate for every patient. Whether PGT is right for you is a discussion with your fertility specialist.

8. Embryo transfer: fresh and frozen

Embryo transfer is the step in which a selected embryo is placed into the uterus. It is a quick procedure, performed in the clinic, usually without sedation. A thin catheter is passed through the cervix under ultrasound guidance, and the embryo is gently released into the uterine cavity. The whole procedure typically takes only a few minutes. Most women describe it as comparable to a Pap smear in discomfort.

Embryo transfer can be done in two ways:

• Fresh embryo transfer — the embryo is transferred a few days after egg retrieval, in the same cycle. This was the traditional approach.
• Frozen embryo transfer (FET) — all embryos are frozen after retrieval, and one is thawed and transferred in a later cycle. This allows the uterus to recover from the stimulation, allows time for genetic testing if performed, and in many situations is reported to give outcomes equal to or better than fresh transfer. Frozen transfer has become substantially more common in recent years as freezing technology has improved.

The choice between fresh and frozen transfer depends on the patient’s individual situation, the response to stimulation, whether PGT was performed, the embryo quality, and the clinic’s protocol.

The number of embryos transferred is also a careful decision. The current trend internationally, supported by major societies including ESHRE and ASRM, is toward single embryo transfer (SET) wherever appropriate, to reduce the risk of twin and triplet pregnancies, which carry higher medical risks for both mother and babies. In specific situations, transferring two embryos may be considered, but this involves accepting a higher chance of multiple pregnancy.

9. The two-week wait and pregnancy test

After embryo transfer, hormone medications (typically progesterone, sometimes others) are continued to support the uterine lining. About 9 to 14 days after the transfer, a blood test is done to measure beta-hCG, the pregnancy hormone. A positive result indicates implantation has occurred. The blood test is repeated a couple of days later to confirm the level is rising appropriately.

The two-week wait between transfer and pregnancy test is often emotionally challenging. Most fertility teams will discuss strategies to manage this period, including realistic expectations about symptoms (or absence of symptoms) and the limited usefulness of home pregnancy tests during this window.

10. Early pregnancy follow-up

If the pregnancy test is positive, the fertility team continues to monitor early pregnancy. An ultrasound scan at around six to seven weeks of pregnancy confirms a pregnancy in the uterus (not ectopic), looks for a heartbeat, and shows the number of embryos that have implanted. Care is then transitioned to standard antenatal care.

If the pregnancy test is negative or if the pregnancy does not progress, follow-up includes a discussion about what may have happened, whether to try again, and whether any changes to the next cycle might help.

Variations and Additions to IVF

Several techniques can be added to or combined with basic IVF, depending on the situation.

ICSI (intracytoplasmic sperm injection)

As described in the cycle walkthrough, ICSI is the laboratory technique in which a single sperm is injected directly into an egg. It is the standard approach when sperm quality is significantly reduced, when previous IVF cycles have had fertilization problems, or when sperm has been retrieved surgically. ICSI is not always required and is not necessarily better than conventional IVF when sperm quality is normal — a point major societies including ASRM have emphasised in recent guidance.

Donor gametes

In some situations, a donor egg, donor sperm, or both is used. Donor eggs are an important option for women with significantly diminished ovarian reserve, premature ovarian insufficiency, or who do not respond adequately to ovarian stimulation. Donor sperm is used when male factor infertility is severe enough that the male partner’s own sperm is not viable, or in other specific situations. The use of donor gametes is regulated and involves additional counselling, screening, and consent. Different countries have different regulatory frameworks for gamete donation.

Fertility preservation

Eggs and embryos can be frozen for later use. Common reasons include before cancer treatment (chemotherapy and some other cancer treatments can affect future fertility), before some surgeries on the ovaries, or in the context of certain medical conditions. Egg freezing is also chosen by some women for personal reasons related to delaying family-building, although the success rates with later use depend strongly on the age at the time of freezing.

Frozen embryo banking

When a cycle produces more good-quality embryos than will be transferred, the extra embryos can be frozen for later transfer. This is the basis of the increasingly common practice of using all frozen transfers after an initial stimulation, sometimes called “freeze-all” protocols.

IVF Success Rates

One of the most common questions patients ask is “What is my chance of success with IVF?” The honest answer is that there is no single number. Success in IVF depends on many factors, and any single percentage taken out of context can be misleading. This section helps explain how to think about success rates and the most important factors that influence them.

What “success” means in IVF

Success in IVF is described in several ways, and it helps to know the difference between them:

• Clinical pregnancy — pregnancy confirmed by ultrasound, usually a few weeks after embryo transfer. Not all clinical pregnancies result in live births; some end in miscarriage.
• Live birth — the actual birth of a baby. This is the outcome that matters most to patients.
• Per cycle versus per transfer — a single IVF cycle (one egg retrieval) may give rise to more than one embryo transfer if embryos are frozen for later use. Success rates “per transfer” appear higher than those “per cycle started” for this reason.
• Cumulative live birth — the chance of having a baby across all the embryo transfers (fresh and frozen) from a single egg retrieval. For many patients this is the most meaningful way to think about outcomes, because most will use all their viable embryos before deciding whether to undergo a further stimulation cycle.

Age is the biggest factor

The single largest factor in IVF success with a woman’s own eggs is her age at the time of treatment. This is because egg quality — particularly the proportion of eggs that are chromosomally normal — declines steadily through the 30s and more steeply through the 40s. The general clinical pattern is:

• Success rates are highest in women under 35
• They decline noticeably through the late 30s
• They decline more steeply through the early 40s
• With a woman’s own eggs, success becomes very low by the mid-40s

Donor egg IVF works differently. Because the eggs come from a younger donor, success depends primarily on the donor’s age rather than the recipient’s. Donor egg IVF can therefore achieve good success rates at ages where own-egg IVF rarely succeeds.

Other factors that affect success

• Cause of infertility — some causes carry a better IVF prognosis than others.
• Ovarian reserve — the number of eggs available for stimulation.
• Embryo quality and stage at transfer — blastocyst-stage embryos generally have higher implantation rates per transfer than earlier-stage embryos.
• Whether PGT was performed — transferring chromosomally normal embryos can improve per-transfer success, although whether this improves cumulative outcomes for every patient is still debated.
• Number of previous failed IVF cycles — success rates may decline modestly with previous failures, although many patients succeed after one or more unsuccessful attempts.
• BMI, smoking, and overall health — weight outside the optimal range and smoking are associated with lower success rates.
• The clinic and laboratory — outcomes vary between clinics for a range of reasons, including patient mix, laboratory standards, and clinical protocols.

A personalised estimate of success from your own fertility specialist — based on your age, your specific cause of infertility, your ovarian reserve markers, and your history — is more meaningful than any general figure. This is a conversation worth having explicitly before starting treatment.

Risks and Complications

IVF is generally safe, but it is medical treatment with real risks. The main risks include:

Ovarian hyperstimulation syndrome (OHSS)

OHSS is a recognised risk of ovarian stimulation, in which the ovaries become enlarged and fluid shifts in the body. Symptoms range from mild (bloating, nausea, abdominal discomfort) to severe (significant abdominal swelling, vomiting, breathing difficulty, blood clots, kidney problems). Severe OHSS is uncommon but a recognised medical emergency. Modern protocols, careful monitoring, and the use of trigger medications other than traditional hCG in higher-risk patients have substantially reduced the rate of severe OHSS.

Risks of egg retrieval

Egg retrieval is generally safe but carries small risks of bleeding, infection, or injury to nearby structures (bladder, bowel, blood vessels). Pain and discomfort are common but usually mild and short-lived.

Multiple pregnancy

When more than one embryo is transferred, there is a risk of twin or higher-order pregnancy. Multiple pregnancies carry higher risks for both the mother (gestational diabetes, hypertension, preterm delivery) and the babies (prematurity, low birth weight, longer-term developmental concerns). The trend toward single embryo transfer in most situations is driven by this concern.

Ectopic pregnancy

Even though embryos are placed into the uterus during IVF, they can occasionally implant in a fallopian tube or elsewhere. The risk of ectopic pregnancy is somewhat higher with IVF than with natural conception, particularly in women with tubal damage. Early pregnancy ultrasounds help identify ectopic pregnancies early.

Miscarriage

Miscarriage rates in IVF pregnancies are similar to those in natural pregnancies at the same maternal age. The chance of miscarriage rises substantially with age regardless of how the pregnancy was conceived.

Long-term considerations

Large studies over the decades since IVF began have been broadly reassuring about long-term outcomes for women and for IVF-conceived children. Ongoing research continues to look at long-term outcomes, particularly with newer techniques. Concerns that surfaced in earlier studies about cancer risk in women undergoing fertility treatment have not been borne out in larger, longer-term datasets. Outcomes for IVF-conceived children, including children conceived with ICSI and PGT, are reassuring overall, though research continues.

Emotional and psychological risks

The emotional impact of IVF is significant and worth recognising as a real consideration. Stress, anxiety, depression, and relationship strain are common during treatment and after unsuccessful cycles. Mental health support is part of comprehensive fertility care.

Emotional and Practical Considerations

The medical aspects of IVF are extensively studied and described, but the lived experience of an IVF cycle is something patient information often understates. A few realities worth naming:

The cycle as a lived experience

An IVF cycle takes over your daily schedule in ways that are easy to underestimate before starting. Multiple injections per day, repeated early-morning clinic visits for monitoring, careful timing of medications, the procedural days for retrieval and transfer, and the long two-week wait afterward all add up. Most people continue working through treatment, but with planning, flexibility, and a willingness to ask for accommodation when possible. Heavy physical work, very stressful periods at work, and major travel are best avoided during the active treatment weeks where possible.

Couples and partner dynamics

IVF involves both partners, but in different ways. One partner is undergoing the daily injections, the monitoring, and the procedures; the other is supporting, often feeling helpless. Differences in how each partner handles stress and disappointment are normal. Many fertility services offer couples counselling, which can be useful at decision points throughout the journey.

Managing disappointment

Not every cycle results in pregnancy, and not every pregnancy results in a baby. The cumulative emotional weight of unsuccessful cycles or pregnancy loss is real. There is no “right” way to grieve a negative pregnancy test or a miscarriage; both deserve recognition and time. Most fertility teams have counsellors available, and many patients find peer support groups helpful.

When to take a break or stop

Most patients do not succeed on the first cycle, and many succeed across several cycles. But IVF is also one of the situations where deciding to stop is a legitimate and sometimes courageous choice. Reasons to take a break or to stop trying include emotional exhaustion, practical limits, deteriorating ovarian reserve making continued attempts less likely to succeed, or simply a sense that the right path forward is something different. These conversations are individual, and there is no universal right answer. Your fertility team should be willing to discuss them openly.

Special Topics

Recurrent IVF failure

When several IVF cycles have not resulted in pregnancy, additional investigations may be considered — closer look at the uterus (sometimes with hysteroscopy), expanded immune or thrombophilia testing in some centres, genetic screening, and review of the cycle protocols. The evidence base for many of the additional investigations and treatments offered for “repeated implantation failure” is variable, and a careful discussion of what is supported by evidence is important.

Fertility preservation before cancer treatment

For women and men facing cancer treatments that may affect future fertility (such as chemotherapy or radiation to the pelvis), fertility preservation before treatment is increasingly offered. For women, this typically involves a short course of ovarian stimulation followed by egg or embryo freezing. For men, sperm banking is straightforward. Discussing fertility preservation with both the cancer team and a fertility specialist soon after a cancer diagnosis is important, because treatment delays for fertility preservation are usually short and the option may not be available once cancer treatment has started.

IVF in older women

Age is the single largest factor in IVF success with one’s own eggs. For women in their late 30s and early 40s considering IVF, success rates are lower than in younger women but still meaningful. For women in their mid-40s and beyond, success with their own eggs becomes very low, and donor eggs become the option that is much more likely to result in a live birth. Many countries also have legal or regulatory upper age limits for IVF, which vary substantially. These are practical considerations to discuss with your fertility specialist.

Frequently Asked Questions

How many IVF cycles will I need?

This varies widely. Some women conceive on the first cycle; many need two or three; some need more. Cumulative success rates rise with successive cycles for several attempts before plateauing. Your fertility specialist can give a personalised estimate based on your specific situation.

Is IVF painful?

Most women describe IVF as uncomfortable rather than painful. Daily injections are usually a brief sting. Ovarian stimulation can cause bloating and abdominal heaviness toward the end. Egg retrieval is performed under sedation; the recovery includes some cramping. Embryo transfer is usually painless. The emotional discomfort of the two-week wait is often described as harder than the physical aspects.

Can I work during IVF?

Most people continue working through IVF, with some flexibility for monitoring appointments and for a few days around egg retrieval. The day of retrieval and the following day are usually best taken off. Embryo transfer typically does not require time off, although some clinics suggest taking the day. Each cycle is individual, and listening to your body matters.

Are IVF children healthy?

Large studies over the decades since IVF began have been broadly reassuring. Most IVF-conceived children are healthy. There is a small increase in some pregnancy-related risks (slightly higher rates of low birth weight, preterm birth) that is partly attributed to the underlying infertility and partly to IVF itself. The use of ICSI and PGT has been studied extensively, with reassuring outcomes overall. Your fertility specialist can discuss the specifics of your situation.

Is there an age limit for IVF?

Two things are worth distinguishing here. Biologically, success with one’s own eggs declines steeply with age, and by the mid-40s the chance of a live birth from one’s own eggs is very low. Donor egg IVF can succeed at older ages because the biology depends on the donor’s eggs rather than the recipient’s. Legally and regulatorily, many countries set upper age limits for IVF treatment. In India, the Assisted Reproductive Technology (Regulation) Act sets an upper age limit of 50 years for the female partner and 55 years for the male partner. Different countries have different rules. The right approach for an older patient depends both on biology and on local regulations, and is best discussed with a fertility specialist who knows the local framework.

Will I have twins?

The risk of twins or higher-order multiples depends on how many embryos are transferred. With single embryo transfer (now the international trend in most situations), the twin rate is very low — comparable to the natural rate of identical twins. Transferring two embryos increases the twin rate substantially. Multiple pregnancies carry higher risks, which is why single embryo transfer has become standard in most appropriate situations.

What happens to embryos I don’t use?

Embryos remaining after a successful pregnancy — or that the patient does not wish to use — can be kept frozen for future cycles, donated to research, donated to other patients (where this is regulated and possible), or allowed to lapse from storage. This is a personal decision and one that is best made with time and counselling. Fertility clinics ask patients to make decisions about embryo disposition at consent, but these decisions can usually be revisited later.

Can stress affect IVF success?

This is a common worry. The research on stress and IVF outcomes is mixed; most large studies have not found that stress significantly affects success rates. Patients should not feel that managing stress is a job they are failing if a cycle does not work. That said, mental health and emotional wellbeing matter for their own sake throughout treatment.

What is the difference between IVF and ICSI?

IVF and ICSI both involve fertilizing eggs outside the body. In conventional IVF, sperm and eggs are combined in a dish and fertilization occurs naturally. In ICSI, a single sperm is injected directly into each egg. ICSI is used when sperm quality is reduced or in certain other situations. The rest of the IVF cycle — stimulation, retrieval, embryo culture, transfer — is essentially the same.

Conclusion

IVF is a well-established treatment that can help build a family in situations where natural conception has not been possible. It involves a sequence of weeks of medications, monitoring, procedures, and waiting, and it asks a great deal of patients emotionally and physically. For many people, IVF leads to a healthy pregnancy and child. For others, it does not, or it takes multiple attempts.

The most useful preparation for IVF is understanding what to expect at each stage, asking detailed questions of your fertility team, and going into the cycle with realistic expectations. A good fertility specialist will tailor the treatment to your individual situation, explain the choices at each step, give an honest estimate of your chances of success, and support you through the cycle. The decisions along the way — how to stimulate, when to retrieve, whether to do ICSI or PGT, fresh or frozen transfer, how many embryos to transfer, when to try again, and when to stop — are all best made together with that team, with information and time to think.
