Preparing for IVF: tests, treatment steps and getting ready for embryo transfer
Share
IVF can feel like a new language: AMH, follicles, ICSI, blastocysts, progesterone and embryo transfer. A clear plan can make the process less overwhelming. This guide explains what you may be asked to check, what happens during treatment, and which questions are worth bringing to your clinic. Your own plan should always come from your fertility team.
Before IVF: understand the reason and the goal
In vitro fertilisation (IVF) means eggs are collected and fertilised with sperm in a laboratory. An embryo may then be transferred into the uterus or frozen for a later attempt. The best approach depends on your age, medical history, ovarian response, sperm factors and previous treatment. Ask why IVF is recommended for you rather than another option, what a “full cycle” includes, and how the clinic will measure success: live births, not only positive tests.
What tests and checks might happen first?
Not every patient needs every test. Your clinic may review:
- Your history and cycle: previous pregnancies or losses, operations, conditions such as PCOS or endometriosis, cycle regularity, medications and any prior fertility treatment.
- Ovarian response: ultrasound assessment of antral follicles and sometimes AMH or other hormones to help plan stimulation. These tests help predict response to medication; they cannot guarantee egg or embryo quality.
- Sperm: semen analysis, with further assessment when results or history suggest it. Ask whether conventional IVF or ICSI is recommended and why.
- Uterus and pelvic health: ultrasound and, when indicated, assessment of the uterine cavity or conditions that could affect the plan. Tubal information may still matter, for example if a fluid-filled tube is suspected.
- Safety and preconception health: infectious-disease screening required by the clinic, review of vaccinations, prescribed medicines and supplements, and other tests guided by your history.
- Consent and practical plans: how eggs, sperm and embryos may be used, stored or discarded, whether donor material is involved, and who to contact if a decision changes.
Ask the clinic which results are essential before starting, which are optional, and what a result would actually change in your treatment.
What happens in an IVF cycle?
- Stimulation: fertility hormones encourage several follicles to grow. Your clinic chooses the protocol and medicine doses, then monitors your response with scans and sometimes blood tests.
- Timing and egg collection: a trigger medicine helps time maturation before egg retrieval. The clinic gives precise instructions for the trigger and collection; follow those rather than a generic timetable online.
- Fertilisation: eggs and sperm are brought together in the laboratory, or ICSI may be used when appropriate. Ask what the recommendation is based on.
- Embryo development: the laboratory observes how fertilised eggs develop over the following days. Not every egg will fertilise, and not every fertilised egg will become an embryo suitable for transfer or freezing.
- Transfer or freezing: the team may recommend a fresh transfer or freezing embryos for a later cycle, depending on safety, the uterine environment and your circumstances.
- Aftercare: you receive instructions about any medication and the date to take a pregnancy test. Testing too early can be misleading.
Why preparation for transfer matters as much as embryo selection
It is natural to hope for the “best-quality embryo.” Embryologists assess development and appearance to help choose an embryo, but a strong grade is not a guarantee of genetic normality, implantation or a baby. A lower-graded embryo may still lead to a pregnancy. Ask what your clinic’s grading means and what it cannot tell you.
Transfer preparation also includes the right timing, an appropriate uterine lining, a clear medication plan and attention to any relevant uterine findings. In a frozen embryo transfer, your clinic may monitor a natural cycle or prepare the lining with medication and time progesterone to the planned transfer. In a fresh cycle, the team also considers your response to stimulation and whether transferring now is advisable. Do not adjust progesterone or other medication yourself: timing is part of the treatment plan.
Ask: Is the uterine cavity adequately assessed for my history? What is the transfer-day plan? Which embryo is recommended, and why? What happens if the lining, hormone timing or your health is not as expected? Would freezing and transferring later be safer or more appropriate? There is no single universal “perfect” lining measurement or add-on that ensures implantation.
One embryo or more?
Transferring more embryos can increase the risk of twins or a higher-order multiple pregnancy, with additional risks for parent and babies. HFEA notes that transferring one embryo and freezing other suitable embryos is often best practice. Ask your clinic for its recommendation for your age, embryo circumstances and personal history, and how it balances chance of a live birth with safety.
Medicines, risks and symptoms worth knowing
Protocols can involve medicines that control the timing of ovulation, hormones that stimulate follicle growth, a trigger before egg collection, and progesterone support around transfer. Your team should explain each medicine, its purpose, cost, timing and side effects. People with a strong ovarian response, including some with PCOS, may need a plan to reduce the risk of ovarian hyperstimulation syndrome (OHSS). IVF also carries risks such as ectopic pregnancy and multiple pregnancy. Seek urgent medical advice from your clinic for significant abdominal pain or swelling, vomiting, faintness, breathing problems or other concerning symptoms.
A practical question list for your clinic
- Why is IVF the best option for me now? What alternatives exist?
- What are your live-birth outcomes for patients like me, and what do those figures include?
- Which tests would change my plan, and which would not?
- What stimulation protocol do you recommend, and how will you manage OHSS risk?
- Why conventional IVF or ICSI in my case? What happens if fertilisation is lower than expected?
- How are embryos assessed? What is the plan for fresh versus frozen transfer, and for any remaining embryos?
- How will you assess and prepare the uterus and time progesterone before transfer?
- How many embryos do you recommend transferring, and why?
- Are any extra tests or treatment “add-ons” being suggested? What evidence shows a better live-birth outcome for someone like me, what are the risks, and what do they cost?
- What is included in the written price: medicines, monitoring, collection, ICSI, freezing, storage and later frozen transfers?
- Whom do I call out of hours, when do I test, and what support is available if the cycle is cancelled or does not work?
Do you need every add-on?
No. Extra tests and procedures can sound reassuring, but HFEA says that for some add-ons there is not enough evidence that they improve outcomes for most patients. There may be a specific reason for one in your case; ask what that reason is, what the evidence shows for live birth, and whether the money and effort would be better spent on standard care or another cycle. You are allowed time to decide.
Prepare the person, not only the protocol
Review preconception folic acid, medications, smoking or alcohol, sleep and any long-term conditions with your own clinician. Arrange practical help for appointment days and ask for counselling or emotional support if you need it. IVF can be physically and emotionally demanding. You do not have to be perfectly calm to deserve good care, and stress alone is not an explanation for a failed transfer.
