Abstract
Unexplained infertility is a term applied to an infertile couple whose standard investigations are normal and whose infertility duration is over two years; therefore, the diagnosis of unexplained infertility is one of exclusion. Unexplained infertility is not an absolute condition but a relative inability to conceive, and while many of these couples may conceive without treatment, treatment will often hasten conception. The incidence varies from 8% to 30%. The standard investigation include detection of ovulation, semen analysis and tubal patency test. Different treatment options in unexplained infertility include: expectant management; clomiphene citrate (CC), or gonadotropins used for ovulation induction; intrauterine insemination (IUI) alone or combined with ovulation induction; and in vitro fertilization and its modifications. The success rates of treatment vary considerably with patient selection, including the age of the woman, the infertility duration and the type of treatment. The ultimate goal of all infertility treatments is the delivery of a healthy baby.
