A prospective study of intrauterine insemination of processed sperm from men with oligoasthenospermia in superovulated women.
The effectiveness of intrauterine insemination (IUI) was compared with that of intracervical insemination (ICI) in 49 infertile couples, in whom the major cause for infertility was oligoasthenospermia. All women had ovulation stimulated with either a clomiphene citrate (CC)-human gonadotropin combination or human gonadotropins alone. The ovulatory dose of human chorionic gonadotropin (hCG) was given after adequate estradiol levels were reached. The timing of inseminations was standardized--IUI was 28 hours after hCG and ICI was immediately after hCG administration. Only one insemination per month was performed with either IUI or ICI. The first treatment cycle was assigned randomly to be either IUI or ICI, and subsequent inseminations were alternated. A total of 182 cycles were completed, with 96 IUIs and 86 ICIs. Pregnancy occurred in eight patients, seven with IUI (14.3%) and one with ICI (2.0%); the difference is significant at P less than 0.05. The pregnancy rate per treatment cycle was 7.3% versus 1.2% (P less than 0.001). This study supports the use of IUI with processed sperm in the treatment of infertility due to oligoasthenospermia.
