Inability to conceive where no cause has been found despite routine testing of semen, ovulation, and pelvic anatomy by laparoscopy.Uterus: Womb. The reproductive organ that houses, protects and nourishes the developing embryo and fetus.

Means that no cause of infertility was found in either the woman or the man.

Infertility for which no obvious cause has been found after the following tests have been done with normal results: a sperm count or postcoital test; a test of ovulation, such as a serum progesterone that is satisfactorily high; and a laparoscopy (used to show that the tubes are open and that there is no endometriosis or other obvious abnormality). Although a hysterosalpingogram (HSG) can substitute for laparoscopy in excluding blockage of the fallopian tubes, an HSG can miss peritubal adhesions and will miss endometriosis. Infertility should not be considered unexplained unless a thorough, careful laparoscopy has been done.

Infertility whose cause cannot be readily determined by conventional diagnostic procedures; this occurs in about 10% of all infertile couples.

Infertility for which the cause cannot be determined with current diagnostic techniques
