You need to be careful when you compare IVF success rates from clinic to clinic.  There are many factors that can make a clinic appear more successful than it really is.  Here is an overview from one clinic that outlines what to consider:

“IVF  Success Rates: Why do they differ so much between clinics?

Couples considering IVF can best evaluate and compare in vitro fertilization clinics when they have a good understanding of the success rates at programs in their area.

Some IVF centers have low pregnancy success rates. Other centers may have high success rates, but also a high rate of triplet or higher pregnancies.

Couples considering IVF treatment should get a written statement of their clinic’s recent success rates and evaluate them in relation to other clinics.

The four biggest variables affecting a program’s IVF success rates are:

  • The quality of the laboratory environment and the skill  of the embryology staff
  • The skill and experience of the reproductive endocrinologist doctor (fertility specialist)
  • The average number of embryos transferred per case
  • The cases taken on by the program for IVF treatment. There are “high-yield” patients and “low-yield” patients. Some couples are more likely to have successful IVF because of egg quantity and quality, female age, or other issues.”

I am not familiar with this clinic specifically but the variables listed are important.  When looking at statistics you also want to look at Fresh transfers vs. Frozen, the age of the patients and whether donor eggs were used.  These can have a huge impact on success rates.

Personally we did three cycles of IVF:

#1  Fresh Embryo Transfer, I was 29, my eggs, my husband’s sperm, 2 embryos transferred to GC (Gestational Carrier) RESULT: Pregnant – one embryo miscarried the other ended up being ectopic

#2 Fresh Embryo Transfer, I was 30, my eggs, my husband’s sperm, 2 embryos transferred to GC (Gestational Carrier) RESULT:Pregnant both embryos miscarried

#3 Frozen Embryo Transfer, I was 35 (but my eggs were frozen 5 years from when I was 30), my eggs, my husband’s sperm, 2 embryos transferred to Different GC (Gestational Carrier) and we were at a different clinic: RESULT: Pregnant-twin girls born at 26 weeks gestation (our GC ended up having Pre-eclampsia)

There are few things I would invest that much time and money into with such unpredictable odds (30-50% success rate) but when it came to having children we thought the risk was worth it.
