Does a woman become infertile if she hasn't been sexually active for a long time?

No, a woman does not become infertile simply due to a lack of sexual activity over time. Infertility is typically related to various medical factors, such as hormonal imbalances, age, or reproductive health issues, rather than sexual activity itself. However, age can impact fertility, as a woman's reproductive capabilities decline as she gets older. It's always best to consult a healthcare professional for personalized advice regarding fertility.
