Probability of Soft-IVF Pregnancy

Since 1985, we have seen close to two thousand babies born. Helping you fulfill your dreams of bringing a new baby into your lives is the sole purpose of Bay IVF’s existence.

Whether your Soft-IVF treatment will be successful depends on several factors, starting with the most important:

  1. Your fertility potential (primarily egg quality)
  2. Excellence of embryology laboratory
  3. Optimized ovarian stimulation
  4. Pure luck


  • The quality of one’s eggs and sperm is the most important factor influencing the probability of success. To optimize your fertility potential, it is very important that you adhere as closely as possible to the reproductive health recommendations.

  • Our state-of-the-art embryology laboratory is directed by Eve Shen, one of the most senior gamete embryologists in the country. Your eggs, sperm, and embryos will receive the highest quality of care.

  • We individualize your treatment protocol. Your ovarian stimulation will be monitored and adjusted as necessary to yield the best quality eggs possible.

  • There are many factors in the field of advanced reproductive medicine which are either unknown or only partially understood. At a certain level, the treatment outcome is beyond one’s control.


Please note that the most influential factor, your fertility potential (especially egg quality), is independent of the performance of a reproductive medicine clinic.

You should expect the same probability of a successful outcome per a transferred embryo with Soft-IVF as with the conventional In Vitro Fertilization.

This table shows the reported nationwide In Vitro Fertilization pregnancy probability.


In Vitro Fertilization Pregnancy Probability


Patient Age

 34 and Younger
35 to 37 38 to 40

   34%       22%   
Number of Embryos Transferred
1.6 1.8 2.0


Since Soft-IVF usually results in the development of fewer embryos compared with conventional In Vitro Fertilization, the cumulative Soft-IVF pregnancy probability will, on the average, be lower than that of conventional In Vitro Fertilization.

The following graph illustrates the approximate increase in successful outcome probability after two and three cycles of Soft-IVF embryo transfer.

Increase Likelihood of Successful Outcome

Cumulative Probability of IVF


In this example, we used an arbitrary 35% successful outcome probability per Soft-IVF embryo transfer. Your actual likelihood of pregnancy could be higher or lower.
