Fertility is a concept that denotes the ability to reproduce healthy offspring. It is applicable to a man, but most often the term is mentioned when speaking of female reproductive capabilities.

Late reproductive: from 40 to 45 years. The hormonal background is unstable, the cycle and ovulation are stable. Beginning of age-related changes in the body. Pregnancy is possible in a natural way, but bearing can require active medical care.

The stage of fading fertility: from 46 to 60 years. There comes a period of menopause. Decreased hormonal background, irregular cycle or its completion. Natural pregnancy is impossible (with very few exceptions), for the gestation will require a course of hormonal drugs
