Understanding IVF Clinic Success Rates: A Comparison of Fresh and Frozen Cycles
With the increasing prevalence of infertility and advancements in reproductive technology, more and more couples are turning to in vitro fertilization (IVF) as a potential solution to their fertility issues. However, with the high cost and emotional toll of IVF, it is important for couples to understand the success rates of different IVF clinics. One key factor that can greatly impact success rates is the type of cycle used – fresh or frozen. In this blog post, we will dive into the differences between fresh and frozen cycles and how they affect IVF clinic success rates.
What is IVF?
Firstly, let’s start with a brief overview of IVF. In vitro fertilization is a process where an egg is fertilized by sperm outside of the body in a laboratory setting. The resulting embryo is then transferred to the woman’s uterus, in hopes of a successful pregnancy. IVF can be used for a variety of fertility issues, including blocked fallopian tubes, male factor infertility, endometriosis, and unexplained infertility.
Fresh vs. Frozen Cycles
Fresh IVF cycles involve the retrieval of eggs from the woman’s ovaries, which are then fertilized with sperm in a laboratory. The resulting embryos are then transferred to the woman’s uterus, typically within 3-5 days. In contrast, frozen cycles involve the retrieval of eggs, fertilization in a laboratory, and then freezing of resulting embryos. These embryos are then thawed and transferred to the woman’s uterus at a later time, typically during a natural cycle or a cycle where the woman’s hormones are regulated with medication.
Success Rates
When it comes to IVF, success rates are typically measured by the percentage of live births per cycle. According to the Centers for Disease Control and Prevention (CDC), the national average live birth rate for fresh IVF cycles is around 40%. However, this rate can vary greatly depending on a number of factors, including age, cause of infertility, and the specific IVF clinic.

Fresh IVF cycles have historically been the most common and popular choice for patients. This is due to the belief that fresh embryos have a higher chance of implantation and success. However, studies have shown that the success rates for fresh cycles may not be as high as initially believed. One study found that the average live birth rate for fresh IVF cycles was only 33%. This can be attributed to a number of factors, including the potential for overstimulation of the ovaries, which can lead to lower-quality eggs and embryos.
Frozen Cycle Success Rates
On the other hand, frozen IVF cycles have been gaining popularity in recent years due to advancements in freezing technology, known as vitrification. This process allows for a higher survival rate of frozen embryos, leading to better success rates. In fact, studies have shown that the average live birth rate for frozen IVF cycles is around 37%, which is slightly higher than the rate for fresh cycles.
Factors Affecting Success Rates
As mentioned earlier, there are a number of factors that can affect IVF clinic success rates, regardless of the type of cycle used. One of the biggest factors is the age of the woman. As women age, their eggs decrease in quality and quantity, making it more difficult to achieve a successful pregnancy with IVF. This is why many IVF clinics have age limits for patients, typically around 35-40 years old.
Other factors that can impact success rates include the cause of infertility, the quality of the sperm and eggs, and the experience and skill of the IVF clinic and medical team. It is important for patients to do their research and choose a reputable and experienced IVF clinic to increase their chances of success.
Conclusion
In conclusion, understanding the differences between fresh and frozen IVF cycles and how they affect success rates is crucial for couples considering this fertility treatment. While fresh cycles have historically been the more popular choice, frozen cycles are gaining traction due to their higher success rates. However, success rates can vary greatly depending on individual factors and the chosen IVF clinic. It is important for couples to consult with a fertility specialist and carefully consider all options before deciding on the type of IVF cycle to pursue.
Summary: IVF is a popular fertility treatment, but it is important for couples to understand the success rates of different IVF clinics. One key factor that can impact success rates is the type of cycle used – fresh or frozen. While fresh cycles have been the more popular choice, studies have shown that frozen cycles may have slightly higher success rates. However, success rates can vary greatly depending on individual factors and the chosen IVF clinic.
