Fourteen couples with long-standing infertility, associated with cervical mucus insufficiency, male subfertility, or unexplained infertility, participated in a therapeutic trial. The female partners, who were all ovulatory, were given human menopausal gonadotropin from day 2 of the menstrual cycle (controlled ovarian hyperstimulation). When plasma estradiol concentrations reached 1000 to 2000 pg/ml, human chorionic gonadotropin was given. Approximately 32 hours and again 70 hours thereafter, a masturbation specimen of the husband's sperm was capacitated in vitro and inseminated transcervically into the uterine cavity. Five women (35%) conceived following a single cycle of treatment. Four of the pregnancies are currently progressing normally; one ended in a spontaneous miscarriage in the early first trimester. The potential role of in vitro sperm capacitation and transcervical intrauterine insemination in the treatment of refractory infertility unrelated to female organic pelvic disease is discussed.

Recent studies report that superovulation combined with intrauterine insemination (IUI) is more successful than superovulation alone, IUI alone or superovulation with intracervical insemination in couples with male subfertility. Our study evaluated two superovulation protocols in the management of male factor infertility using IUI: (A) clomiphene citrate and human chorionic gonadotropin (HCG) and (B) human menopausal gonadotropin and HCG. Fifteen couples with severe oligoasthenozoospermia (OAS) were treated with protocol A in 54 cycles, and no pregnancies were achieved. Eight of the 15 couples with severe OAS subsequently received protocol B for 24 cycles and elicited no pregnancies. Thirty-seven couples with moderate OAS received protocol A for 169 cycles, and 2 pregnancies ensued (5.4% per couple and 1.12% per cycle). Twelve of the 35 nonpregnant couples with moderate OAS then received protocol B for 31 cycles, and 4 pregnancies were recorded (33.3% per couple and 12.9% per cycle).
