Not only is the age at which a woman becomes a mother being delayed, but this is also associated with a delay in parenthood. The negative effects of age on male fertility are less well known than on female fertility, but it is clear that in the case of men the effect on fertility is not as drastic.
Nevertheless, it is advisable for a man to become a father before the age of 40. Advanced paternal age is associated with:
- Decreased sperm quality.
- Longer time to achieve gestation.
- Risks to the baby.
However, this does not mean that a man cannot father a healthy baby after the age of 40.
