IVF procedure yields a very high success rates as compared to other methods of Assisted Reproductive Technology (ART). For Specialized Centres and Doctors it maybe as high as 68% (please refer to ELA Blogs for more specific Success Rates by Centres in India), while for Centres with lesser experience it maybe as low as 12%. However, the outcome may also vary from couple to couple depending on following factors such as:
- Women with high maternal age (older than 40 years) have lesser chance to achieve pregnancy through IVF than a young woman due to ovarian reserve and ovarian cell issues.
- Women who were previously pregnant successfully has two times higher the chance than women who never conceived prior to IVF.
- Genetic factors like chromosomes, DNA, RNA etc. vary from person to person and one with good gene pool has more chance to conceive through IVF.
- Women with hormonal problems such as high level of PCOS (Polycystic Ovary Syndrome) have slightly lower chances of IVF success than women without such problems. However the percentage change is very minimal.
- Women with weight issues fetches lower chances of IVF success than a healthy woman.
- IVF success rates also depend on the sperm quality (count, motility etc.) of the father/donor. Those with problems with sperm are suggested to go for additional method such as ICSI (intracytoplasmic Sperm Injection), MESA (Microsurgical Epididymal Sperm Aspiration), TESA (Testicular Sperm Aspiration) etc. combined with IVF method.
