Cause


Infertility has many causes that involve either the woman's, the man's, or both partners' reproductive systems. Some causes include:

Rates of infertility and miscarriage increase with age. A woman's fertility peaks in her late 20s and gradually begins to decline in her early 30s. A more pronounced drop in fertility and increase in miscarriage risk begins around her mid-30s, primarily due to the aging egg supply. Male fertility also decreases with age but it is a more gradual decline than in women.
