Relationship between getting older and ability to reproduce among females
Female fertility is affected by age and is a major fertility factor for women. A woman's fertility is in generally good quality from the late teens to early thirties, although it declines gradually over time.[1] Around 35, fertility is noted to decline at a more rapid rate.[1] At age 45, a woman starting to try to conceive will have no live birth in 50–80 percent of cases.[2] Menopause, or the cessation of menstrual periods, generally occurs in the 40s and 50s and marks the cessation of fertility, although age-related infertility can occur before then.[3] The relationship between age and female fertility is sometimes referred to as a woman's "biological clock."[4]
