Infertility is a reproductive disorder caused by various etiologies, representing an adverse reproductive health event for couples of childbearing age. For women, if there is no contraception and they have had sexual intercourse for at least 12 months without conceiving, a diagnosis of infertility can be made. In men, this condition is referred to as sterility. Infertility can be divided into two main categories: primary and secondary infertility. Primary infertility is when a person has never conceived despite not using contraception, whereas secondary infertility occurs when a person has previously been pregnant but fails to conceive again after 12 months of unprotected intercourse.
