उत्तर
Reproductive age in women starts when their menstruation starts.
Explanation:
In females, the reproductive phase of life begins at puberty (10 to 12 years of age) and generally lasts till the age of approximately 45 to 50 years. If fertilisation does not occur, the released egg, the thickened lining of the uterus, and its blood vessels are shed off. This causes bleeding in women, which is called menstruation.
