IVF Process FAQ
Common questions about the IVF treatment process, from initial consultation to embryo transfer.
How long does one IVF cycle take?
A typical IVF cycle takes 4-6 weeks from the start of medication to embryo transfer. This includes 10-14 days of ovarian stimulation, egg retrieval, 3-6 days of embryo development, and the transfer procedure.
What happens during egg retrieval?
Egg retrieval is a minor surgical procedure performed under sedation. Using ultrasound guidance, a thin needle is inserted through the vaginal wall to aspirate follicles and collect eggs. The procedure typically takes 15-30 minutes.
How many embryos should be transferred?
Many reproductive endocrinologists discuss single embryo transfer (SET) when a patient has a good-quality blastocyst and a clinical profile where SET is appropriate. It can reduce the risk of multiple pregnancy, but your clinic should guide the recommendation for your age, embryo history, and treatment plan.
What is the difference between Day 3 and Day 5 transfer?
Day 3 embryos are cleavage-stage embryos, while Day 5 embryos are usually blastocysts. Many clinics review embryo development, lab history, and patient-specific factors before recommending a Day 3 or Day 5 transfer.
How many IVF cycles does it typically take?
Outcome averages vary by age, diagnosis, embryo source, clinic lab, and treatment history. Cumulative rates can rise across multiple cycles, but published averages cannot predict your individual path. Your clinic can help interpret the estimate that best matches your situation.
Can I exercise during IVF?
Light to moderate exercise is generally safe during early stimulation. However, once follicles grow larger (typically after day 5-6 of stims), high-impact activities should be avoided due to the risk of ovarian torsion.
What are the side effects of IVF medications?
Common side effects include bloating, mood changes, breast tenderness, headaches, and injection site reactions. More serious but rare complications include OHSS (ovarian hyperstimulation syndrome).
How soon after retrieval can I return to work?
Most patients take 1-2 days off after retrieval. Mild cramping and bloating are normal. Strenuous activities should be avoided for about a week.
What is a frozen embryo transfer (FET)?
A FET involves thawing and transferring a previously cryopreserved embryo. Some people find FET cycles less physically demanding than a fresh retrieval cycle, but timing, medications, and expected outcomes depend on your clinic protocol and history.
Does IVF increase the risk of birth defects?
Large studies show IVF babies have a very slightly increased risk of certain conditions, but the absolute risk remains low. Most experts attribute this to underlying infertility factors rather than the IVF process itself.
