How Does Age Affect IVF Success Rates?

In vitro fertilisation (IVF) has provided hope to many couples facing infertility, but the success rates of IVF treatments can vary significantly based on several factors, including the age of the woman undergoing the procedure. Understanding how age affects IVF success rates is crucial for making informed decisions about fertility treatments. Here, we explore the impact of age on IVF success, particularly in the context of accessing the best IVF treatment in Delhi.

The Biological Clock and Fertility

1. Egg Quality and Quantity

Women are born with a finite number of eggs, which decline in quantity and quality as they age. When a woman reaches her mid-30s, the number of viable eggs decreases more rapidly. This decline becomes more pronounced after age 35 and even more after age 40.

• Egg Quality: As women age, the likelihood of chromosomal abnormalities in eggs increases, which can affect embryo quality and increase the risk of miscarriage.
• Egg Quantity: The ovarian reserve, or the number of eggs remaining in the ovaries, diminishes with age, making fewer eggs available for retrieval during an IVF cycle.

2. Hormonal Changes

Age-related hormonal changes can also impact fertility. For instance, levels of follicle-stimulating hormone (FSH) and luteinising hormone (LH) can fluctuate, affecting the regularity and quality of ovulation. Higher FSH levels often indicate a reduced ovarian reserve and can predict lower IVF success rates.

IVF Success Rates by Age

1. Women Under 35

IVF success rates for women under 35 are generally higher than those for older age groups. This age group typically has more healthy eggs, leading to higher implantation and pregnancy rates.

• Success Rate: Approximately 40-50% per cycle.

2. Women Aged 35-37

Women in this age bracket experience a slight decline in IVF success rates. However, many still achieve successful pregnancies, especially with the help of advanced reproductive technologies.

• Success Rate: Approximately 30-40% per cycle.

3. Women Aged 38-40

For women aged 38 to 40, the success rates of IVF begin to decline more noticeably. The reduced ovarian reserve and increased risk of chromosomal abnormalities contribute to this decline.

• Success Rate: Approximately 20-30% per cycle.

4. Women Over 40

Women over 40 face the most significant challenges with IVF success. Combining fewer eggs, lower egg quality, and hormonal changes reduces the likelihood of successful implantation and pregnancy.

• Success Rate: Approximately 10-20% per cycle, decreasing further with each year beyond 40.

Factors Influencing IVF Success in Older Women

1. Use of Donor Eggs

One effective strategy for older women is the use of donor eggs. Donor eggs typically come from younger women with healthy ovarian reserves, significantly improving the chances of a successful pregnancy.

• Success Rate with Donor Eggs: It is similar to the rates for women under 35, around 40-50% per cycle.

2. Preimplantation Genetic Testing (PGT)

PGT is a technique used to screen embryos for chromosomal abnormalities before implantation. This testing can help ensure that only healthy embryos are transferred, increasing the chances of a successful pregnancy and reducing the risk of miscarriage.

3. Advanced Maternal Age and Complications

Older women are more likely to experience complications during pregnancy, such as gestational diabetes, hypertension, and preterm birth. Comprehensive prenatal care and monitoring are essential to manage these risks effectively.

The Role of Advanced IVF Techniques

1. Assisted Hatching

Assisted hatching is a technique for helping embryos hatch from their protective outer layer and implant into the uterine lining. This method can be particularly beneficial for older women or those with previous failed IVF cycles.

2. Intracytoplasmic Sperm Injection (ICSI)

ICSI involves injecting a single sperm directly into an egg to facilitate fertilisation. This technique can be helpful for couples with male infertility issues and can enhance the fertilisation process in older women.
