How Age Affects Fertility and IVF Success Rate


Posted July 8, 2025 by Rudhravenu

Know about success rate of In Vitro Fertilization (IVF) according to age.

 
Age is one of the most influential factors when it comes to fertility and the success rate of assisted reproductive treatments like IVF (In Vitro Fertilization). While modern medicine has made it possible for many individuals to conceive later in life, the natural decline in reproductive potential with age still plays a critical role. Understanding how age affects fertility can help couples make informed decisions and seek timely treatment from the right IVF centre in Coimbatore.

Female Fertility and Age
Women are born with a fixed number of eggs, and this number gradually decreases with age. Not only does the quantity decline, but the quality of eggs also reduces, making it harder to conceive naturally or even through IVF. The most fertile years for a woman are generally between the early 20s to early 30s. After 35, the decline in fertility becomes more noticeable, and by the age of 40, it becomes significantly challenging to achieve pregnancy.
Key Changes That Occur with Age:
• Decrease in ovarian reserve: Fewer eggs are available as a woman ages.
• Decline in egg quality: Older eggs are more likely to have chromosomal abnormalities.
• Increased risk of miscarriage: The chances of pregnancy loss rise after the mid-30s.
• Hormonal changes: These can affect ovulation and implantation.

Male Fertility and Age
Although men can produce sperm throughout their lives, sperm quality also declines with age. After the age of 40, there is often a decrease in sperm count, motility (movement), and morphology (shape). Additionally, older sperm can carry a higher risk of genetic mutations, which may affect embryo development or increase the risk of certain birth defects.

IVF Success Rate by Age
IVF offers hope for many couples struggling to conceive, especially those affected by age-related fertility issues. However, age still significantly impacts the chances of IVF success.
IVF Success Rate Chart by Female Age (Average Data):
Age Group Success Rate (per IVF cycle)
Under 35 40% to 50%
35 to 37 30% to 40%
38 to 40 20% to 25%
41 to 42 10% to 15%
Above 43 Less than 5%
The decrease in success rate is primarily due to lower egg quality and reduced implantation potential in older women. IVF using donor eggs is often recommended for women over 40 to improve the chances of a successful pregnancy.

How to Improve IVF Outcomes Despite Age
While age is a factor that cannot be changed, there are several ways to optimize fertility and improve IVF outcomes:
• Early Fertility Assessment: Women in their early 30s or those with irregular cycles should consider checking their ovarian reserve.
• Egg Freezing (Oocyte Cryopreservation): This is ideal for women who wish to delay childbearing while preserving younger, healthier eggs.
• Healthy Lifestyle: A balanced diet, regular exercise, and avoiding smoking or alcohol can enhance fertility.
• Use of Donor Eggs or Sperm: In cases of poor egg or sperm quality, donors can offer a higher chance of success.
• Advanced IVF Techniques: Methods like ICSI, blastocyst transfer, and preimplantation genetic testing (PGT) can improve outcomes.
