Infertility is a fertility disorder due to various disease causes. It is generally called infertility when there is no pregnancy for more than 12 months in the absence of measured intercourse. Infertility is generally divided into two categories: primary infertility and secondary infertility. Primary infertility is a condition in which there has never been a history of pregnancy and no pregnancy has occurred without contraception. Secondary infertility is a condition in which there is a history of previous pregnancies, that is, a previous birth of a child, but no pregnancy occurs after 12 months of intercourse without contraception. There are many factors that can cause infertility, such as pelvic factors, which can cause infertility when there are adhesions and inflammation in the fallopian tubes and when pelvic inflammatory disease is present. There are also uterine factors, including endometriosis, which can cause infertility. In addition, infertility may occur when sperm quality is poor or ovulation is impaired. If the condition is actively treated, there is still a possibility of pregnancy.
