IVF Success Rates & Statistics | PFCLA IVF Clinic Blog

Are you considering IVF and wondering about your chances of success? Understanding IVF success rates and statistics are crucial in making informed decisions about your fertility journey. In this blog post, we’ll delve into the factors that influence in vitro fertilization success rates, explore the average success rates at different ages, and provide valuable insights to help you navigate the process. Whether you're just starting your research or preparing for your first IVF cycle, this information will equip you with the knowledge you need to make confident choices. 

What is IVF?

In Vitro Fertilization (IVF) is a medical procedure that involves fertilizing eggs with sperm outside of the body. This process is done in a laboratory setting, and the resulting embryos are then transferred to the uterus with the hope of implantation and pregnancy. 

IVF is often chosen by couples or individuals facing infertility challenges. Some common reasons for opting for IVF include: 

• Blocked fallopian tubes: This prevents eggs from reaching the uterus for fertilization. 
• Endometriosis: A condition where tissue like the uterine lining grows outside of the uterus, which can interfere with fertility. 
• Male infertility: Issues such as low sperm count or poor sperm quality can make natural conception difficult.
• Advanced maternal age: As women get older, their fertility declines, making it harder to conceive naturally. 
• Previous failed fertility treatments: If other methods like intrauterine insemination (IUI) have been unsuccessful, IVF may be considered. 
• Genetic testing: IVF can allow for preimplantation genetic testing (PGT), which helps identify embryos with certain genetic disorders before they are transferred. 

IVF Success Rates & Statistics

IVF has become an increasingly popular fertility treatment as more people seek to start families. In the United States, it remains the dominant option, accounting for 99% of all cycles in 2021, with hundreds of thousands of IVF cycles performed annually. 

Thanks to advancements in technology and medical practices, IVF success rates have improved significantly. Factors like enhanced egg retrieval, embryo culture, and transfer techniques have contributed to higher chances of success. However, individual outcomes can still differ based on age, infertility cause, and overall health. 

IVF Success Rates by Age

IVF technology has made significant advancements since its inception in 1985. Success rates have improved, with women under 35 now experiencing live birth rates of almost 55%. This represents a significant increase of approximately 266.7% since the technology was first introduced. 

The CDC recorded over 400,000 fertility treatment cycles that year, with the average age of women undergoing ART increasing to 36.4. 

The success of IVF is evident in the rise of live births. The CDC reports a significant increase in live births from embryo transfers since 2015. However, it's important to note that individual clinic success rates can vary. PFCLA, for instance, has demonstrated a higher live birth rate compared to the national average.

IVF Success Rates for Different Techniques

There are various IVF techniques available, each tailored to the specific needs of the patient. The different methods may be more suitable depending on factors such as sperm quality and fertility challenges. It's essential to consult with a fertility specialist to determine the best IVF approach for your individual situation.

Comparing Fresh vs Frozen Embryo Transfers

The decision between fresh embryo transfers (ET) and frozen embryo transfers (FET) is a critical one in the IVF process. While both methods have their advantages, understanding the data can  

A recent study examined the maternal and neonatal outcomes of women undergoing their first fresh or frozen embryo transfer. The study included 720 women of advanced maternal age who underwent a first fresh ET (n = 375) or FET (n = 345) between January 2016 and April 2021. 

Key Findings: 

• Live birth rates: There was no significant difference in live birth rates between FET and fresh ET. 
• Clinical pregnancy rates: FET had slightly lower clinical pregnancy rates compared to fresh ET. 
• Birthweights: FET resulted in slightly higher birthweights. 
• Preterm births: FET was associated with a lower risk of preterm births. 

Comparing Single vs Multiple Embryo Transfers

Historically, Multiple Embryo Transfer (MET) was associated with higher success rates due to the increased likelihood of implantation. However, studies have shown that Single Embryo Transfer (SET) can achieve similar outcomes, especially when combined with preimplantation genetic testing (PGT). For instance, a study published in the Journal of Developmental Medicine & Child Neurology (DMCN) found no significant difference in live birth rates between SET and MET when high-quality embryos are transferred. 

Multiple Births 

One of the primary concerns with MET is the increased risk of multiple births, such as twins or triplets. These pregnancies can pose significant health risks for both mother and babies. SET significantly reduces the risk of multiple births, leading to improved outcomes for both mother and child. 

Factors to Consider 

When deciding between SET and MET, several factors should be considered: 

• Embryo quality: High-quality embryos have a better chance of implantation, making SET a viable option even with a single embryo. 
• Age: Younger women may have higher success rates with SET, while older women may benefit from transferring multiple embryos. 
• Health history: Women with a history of recurrent miscarriages or fertility issues may opt for MET to increase their chances of success. 
• Personal preferences: Ultimately, the decision should be made in consultation with a fertility specialist based on individual circumstances and preferences. 

By prioritizing Single Embryo Transfer, PFCLA aims to provide patients with the best possible outcomes while minimizing the risks associated with multiple births

What Factors Impact IVF Success Rates?

As there is a significant correlation between a woman's age and the likelihood of a successful IVF treatment. This trend is likely due to several biological factors, including: 

• Decreasing egg quality: As a woman ages, her ovarian reserve diminishes, and the quality of her eggs may decline. This can reduce the chances of fertilization and implantation. 
• Increased risk of chromosomal abnormalities: Older eggs are more prone to genetic errors, which can lead to miscarriages or the birth of children with chromosomal conditions. 
• Uterine changes: The lining of the uterus, where the embryo implants, can become thinner and less receptive to implantation as a woman ages. 
• Hormonal imbalances: Hormonal fluctuations can affect the fertility process, particularly as a woman approaches menopause. 

Despite these challenges, many women over 35 successfully conceive through IVF. However, the success rates are generally lower compared to younger women. It's important for individuals considering IVF to discuss their age and other relevant factors with their healthcare provider to make informed decisions about their fertility journey.

Tips to Improve Your Chances of Success with IVF

Improving IVF success rates often involves a combination of factors, including: maintaining a healthy lifestyle, managing stress, choosing a reputable clinic, and following your doctor's recommendations. Additionally, factors like age and underlying health conditions can influence outcomes.
