South African Egg Donation IVF Success Rate

Success Rates Of Donor Egg IVF Reviewed

A note regarding “success rate”

The most important factor to consider when reviewing success rates is the cariables that exist in the publication of success rates. Success rates may be documented and claimed based on the following:

  • The success rate % and on how many actual transfers this % is based. i.e: 50% and 10 egg donation IVF’s versus 50% on 200 procedures.
  • Whether the success rate % is based on a heartbeat at 6 weeks, pregnancy or live births.
  • If the success rate is based on the embryo transfer using fresh or frozen/thawed embryos will result in different statistics.
  • Whether fresh embryo transfer is based on day 3 or day 5 transfer.

Finally it must be noted that the success rate of any IVF cycle will always be influenced by a patient’s medical characteristics, the quality of the sperm, the condition of the uterus and the treatment protocol.
