The types of infertility, with their respective frequencies, are tubal and pelvic pathology (35%), male problems (35%), anovulation (15%), unexplained infertility (10%) and other infrequent problems (5%). While anovulation, mild/moderate endometriosis, unexplained infertility and moderate oligozoospermia can be treated with mild ovarian stimulation and timed intercourse and/or intrauterine insemination (IUI), no treatment options are available for nonoperable tubal problems or treatment failures with IUI.\n- Type\n- Research Article\n- Information\n- Copyright\n- © 2001 Cambridge University Press","source_license":"CC0","license_restricted":false}
