Infertility refers to the inability of a person or a couple to conceive or carry a pregnancy to term after a significant period of trying to conceive. It is typically diagnosed when a couple has been trying to conceive for one year or longer (or six months or longer for women over the age of 35) without success. Infertility can be caused by a variety of factors, including issues with the reproductive system, hormonal imbalances, genetic factors, lifestyle and environmental factors, and certain medical conditions.
It can affect both men and women, and may be temporary or permanent. Infertility can have emotional, psychological, and social impacts on individuals and couples, and it may require medical intervention or fertility treatments to improve the chances of conceiving.
