How Long Does One Cycle of IVF Take?

  • Overall Duration: About 4–6 weeks for a complete IVF cycle.

  • Initial Consultation & Tests: 1–2 weeks (varies per patient).

  • Ovarian Stimulation: 10–12 days of hormone injections.

  • Monitoring Appointments: Every 2–3 days during stimulation.

  • Egg Retrieval: Performed 34–36 hours after the trigger injection.

  • Fertilization & Embryo Culture: 3–5 days in the lab.

  • Embryo Transfer: Usually on day 3 or day 5 after egg retrieval.

  • Pregnancy Test: 12–14 days after embryo transfer.

 

How Many Embryos Are Transferred During IVF?

1. Standard Practice: Single-Embryo Transfer (SET)

  • Most modern IVF clinics prefer transferring one high-quality embryo at a time.

  • This approach reduces the risk of multiple pregnancies (twins or triplets), which can carry complications.

2. Based on the Age of the Woman

  • Under 35 years: Usually, one embryo is recommended.

  • 35–40 years: Sometimes one or two embryos may be considered.

  • For patients over 40 years old, doctors may consider transferring two embryos, depending on embryo quality and medical history.

3. Embryo Quality Matters

  • If the embryo is a high-quality blastocyst, a single transfer is usually enough.

  • Lower-grade embryos may require two embryos to increase the chances of implantation.

4. Previous IVF Failures

  • If a patient has had multiple failed IVF cycles, the doctor may consider transferring two embryos to improve the probability of success.

5. Patient Preference (But with Doctor Guidance)

  • Some patients request more embryos to increase chances, but clinics encourage decisions based on safety and medical evidence.

6. Risk of Multiple Pregnancy

  • Transferring more than one embryo increases the chance of twins or triplets, which may lead to:

    • Preterm birth

    • Low birth weight

    • High-risk pregnancy

    • Complications for both the mother and the babies

7. International Guidelines

  • Global reproductive organizations such as ASRM, ICMART, and ESHRE recommend single-embryo transfer, especially with blastocysts.

8. Use of Frozen Embryos (FET)

  • With frozen embryo technology, patients can safely transfer one embryo per cycle and use remaining embryos in future attempts.
