It is well known that female fertility declines with age, but new research reveals that the male partner’s age also plays a significant role in IVF treatment chances. While stories of celebrities fathering children into their sixties or even seventies are not uncommon, the data presents a clearer picture about fertility that couples should be aware of.
Key Findings from Recent Research
During the 33rd Annual ESHRE meeting in Geneva this past July, scientists presented findings from nearly 20,000 IVF treatment cycles conducted in the USA from 2000 to 2014. The study revealed that as male partners age, the birth rates for women in the same age group decrease. For instance:
- Women Aged 35-40: Success rates dropped from 70% with a younger partner to 54% when the partner was over 40.
Additionally, data from the UK indicates that couples where the male partner is over 40 are, on average, 30% less likely to conceive within the first 12 months of trying.
Impact of Male Age on Fertility
Dr. Laura Dodge from Harvard, a key researcher in the study, notes that higher male age not only prolongs the time to conception but is also associated with a higher risk of miscarriage. Although the exact causes remain unclear, decreased sperm quality is a significant factor, along with age-related diseases that may further impact fertility.
Pro Tips for Men: If you’re concerned about sperm quality, consider maintaining a healthy lifestyle by:
- Eating a balanced diet
- Exercising regularly
- Avoiding smoking and excessive alcohol consumption
The Dominant Role of Female Age
It’s important to highlight that female age is still the more significant factor in fertility. The study indicates that the relative decrease in success rates between women below 30 and those over 40 is 46%, more than double that of men in the same age groups (20%).
Conclusion
Understanding the impact of both partners’ ages on IVF success is crucial for couples planning to conceive. By staying informed and adopting healthy lifestyle choices, couples can enhance their chances of successful conception.
