Understanding Success Rates

Fresh-Success-Chart

 Understanding success rates with IVF is essential to estimate your likelihood of conceiving.

 

Key factors influencing a fertility center’s IVF pregnancy rates include, the skill and experience of the reproductive endocrinologist, the skill and experience of the embryologist as well as the quality of the laboratory environment, the number of embryos transferred per case, and the nature of the cases taken on by the clinic. There are “highly complex cases” and “straight-forward cases”. 

 

It is important to look at sample size (i.e., number of treatment cycles performed per group or category). The sample size of a statistical sample is the number of observations that constitute it. The sample size is an essential feature of any study in which the goal is to make inferences about a population from a sample. Larger sample sizes generally lead to increased precision when trying to estimate an unknown parameter.

 

 The Table below shows our IVF historical pregnancy rates per embryo transfer procedure. Ultrasound confirmed pregnancies are examined at six to eight weeks by the physician. A gestational sac and heartbeat is then confirmed by ultrasound imaging.

 

IVF results are presented grouped by patient’s age. Egg Donation cycles are grouped together under a separate category (all egg donors are younger than 34 years old). 

 

Age alone is not the only factor influencing IVF outcomes. Many other factors which include presence or absence of male factor infertility and it’s severity, ovarian reserve, antral follicle count, baseline FSH and AMH levels, prior successful or unsuccessful treatments, surgeries, endometriosis, uterine anomalies,  tubal factors (such as hydrosalpinx), and genetic factors ALL will directly or indirectly affect the success of an IVF cycle.

 

Patient medical characteristics and circumstances do vary among clinics. The same is true of a clinic’s acceptance criteria and treatment approaches; therefore, these data should not be used for comparisons among clinics.
