In recent years, research has increasingly focused on how age affects male fertility and the potential genetic risks associated with fathering children later in life. While sensational headlines sometimes exaggerate the risks, the underlying science offers important insights for men, couples, and families planning for the future.
Male Fertility and Aging
It is commonly known that women experience a decline in fertility after the age of 35. However, men are not immune to the effects of aging on reproductive health. Scientific studies indicate that after the age of 40–45, men may experience:
- Reduced sperm quality: Sperm motility and morphology can decrease over time.
- Increased DNA fragmentation: Older sperm may carry more genetic errors.
- Changes in hormone levels: Testosterone production naturally declines with age, which can affect sperm production.
While men can technically father children at older ages, these changes can affect conception and may contribute to higher risks of certain genetic conditions in offspring.
