Problems with eggs

[Cami]

The number of eggs may be low, or the quality may be poor.
(See also Overview of Infertility.)
The number and quality of eggs (ovarian reserve) may begin to decrease at age 30 or even earlier. They decrease rapidly after age 40. But age is not the only reason that the number and quality of eggs decrease. Abnormalities in the ovaries can also cause such a decrease.
In primary ovarian insufficiency (sometimes called premature menopause), the number of eggs in the ovaries decreases early. In a few women, primary ovarian insufficiency is the reason they have irregular menstrual periods or no periods.
