Infertility refers to the condition where, after a couple has married and cohabited for more than a year, despite having regular sexual intercourse without any contraception, they are unable to conceive naturally. There are many factors that can cause infertility, including factors related to the male, the female, or both. Male factors account for about 40% of infertility cases, female factors account for about 50%, and combined factors account for about 10%. Female infertility includes ovarian infertility, fallopian tube infertility, uterine infertility, cervical infertility, vaginal infertility, immunological infertility, and more.
