Understanding the Age and IVF relation: How Couples’ age affects IVF Success

How Female Age Affects IVF Success

Women are born with a finite number of eggs. Both the quantity and quality of these eggs decline with age. Here’s how age impacts female fertility and IVF success:

• Under 35 Years: Women in this age group have the highest IVF success rates, often ranging between 40-50% per cycle.
• 35-40 Years: Fertility begins to decline, with success rates dropping to about 30-40% per cycle.
• Over 40 Years: The quality of eggs significantly diminishes, reducing success rates to 10-20% per cycle, and by the mid-40s, the chances of a successful pregnancy drop below 5%.

The decline in egg quality also increases the risk of chromosomal abnormalities, leading to a higher likelihood of miscarriage and genetic disorders such as Down syndrome.

Male Age and IVF Success

Although men produce sperm throughout their lives, sperm quality declines with age. Factors such as reduced motility, DNA fragmentation, and lower sperm count can impact fertilization and embryo quality. Studies suggest that men over 40 may have lower success rates with IVF compared to younger men.

How to Improve IVF Success Rates with Age

While age is a significant factor, several strategies can help improve IVF outcomes:

1. Egg or Embryo Freezing (Fertility Preservation): Women who wish to delay pregnancy can freeze their eggs at a younger age to use in later IVF cycles.
2. Preimplantation Genetic Testing (PGT): This helps identify embryos with normal chromosomes, increasing the chances of a healthy pregnancy.
3. Use of Donor Eggs: Women with diminished ovarian reserve may consider donor eggs from younger women to improve success rates.
4. Optimized Lifestyle Choices: Maintaining a healthy diet, reducing stress, avoiding smoking and excessive alcohol consumption, and managing weight can enhance fertility.
5. Advanced Sperm Selection Techniques: For older men, specialized sperm selection methods can help improve fertilization rates.

When to Seek Fertility Assistance

• If you are under 35 and have been trying to conceive for over a year.
• If you are over 35 and have been trying for more than six months.
• If you have known fertility issues, such as PCOS, endometriosis, or a history of miscarriages.
• If you are considering fertility preservation for future pregnancy plans.

Conclusion

Age is an essential factor in IVF success, but with modern fertility treatments and proactive planning, many couples achieve successful pregnancies. If you are concerned about age-related fertility issues, consulting with a fertility specialist can help you explore the best options for your journey to parenthood.

If you’re considering IVF, don’t let age be a barrier—understanding your options and taking early action can significantly improve your chances of success.
