Understanding IVF Success Rates and Their Effect on Your Treatment

The process of choosing the right fertility clinic will be shaped by a number of factors, including the practice’s in vitro fertilization (IVF) success rates. At the Fertility Center of San Antonio, we are proud of our impressive record in helping our clients become parents. Understanding IVF success rates can be confusing at first, and at our San Antonio, TX, practice, we want to ensure that all our patients are fully educated on the IVF process. We have compiled some helpful tips on what the numbers mean in an IVF success report, and what to look for in the charts. To learn more about our IVF processes and statistics, please reach out to us today.

Total IVF Cycles Performed Per Year

Initially, you will want to verify that a fertility clinic is performing an adequate number of IVF cycles every year. The total number of cycles performed annually is a sign that the clinic is experienced and proficient in IVF. The general consensus is that a clinic should be averaging more than two cycles a week, or about 120 a year. At the Fertility Center of San Antonio, we perform over 500 IVF cycles a year, or about 10 a week.

Fresh vs. Thawed Embryos

During a fresh IVF cycle, a woman’s eggs are taken from the ovaries, inseminated in the lab, matured in an incubator, and implanted back into her uterus. In this case, the embryologist or doctor chooses the healthiest embryos for implantation.

A fresh cycle differs from a thawed embryo cycle, which uses frozen and thawed embryos. Success rates tend to be lower with thawed embryos compared to fresh embryos. Due to the extra steps involved in the freezing and thawing process, there is a greater potential for mishandling or damage to the embryos.

Non-donor vs. Donor Eggs

The majority of women will use their own eggs (non-donor) as part of an IVF cycle. Conversely, patients can use eggs donated from another woman. The decision to use donated eggs is often linked to age, and tends to be a more common practice for patients 40 and older.

Age-related Success Rates

In addition to identifying whether you will be using frozen, thawed, non-donated, or donated eggs, you will also want to identify your age group. Considerations about IVF and age include:

  • Under 35: this group has the most favorable chances of IVF success
  • 35-37: this segment still has favorable statistics for successful IVF results
  • 38-40: this age group has a somewhat favorable IVF outcome; good statistics in this group are a strong sign of high quality care
  • 41 and over: in this age category, fertility doctors may recommend egg donation, since IVF with non-donated eggs can be challenging

Percentage of Transfers Resulting in Live Births

The percentage of transfers resulting in live births is the best way to evaluate a fertility clinic's IVF success rate. This statistic indicates how many completed cycles resulted in a live birth - or pregnancy carried to term. This number excludes retrieval without transfers, or IVF cycles that were started but not finished for any number of reasons. The Fertility Center of San Antonio boasts success rates that are higher than the national average.
