abstract

  • Homologous artificial insemination (AIH) is used to treat infertility caused by oligoasthenospermia, despite the lack of controlled studies confirming its benefit. This prospective randomized controlled trial was undertaken to determine whether intracervical (IC-AIH) or intrauterine (IU-AIH) homologous artificial insemination improves pregnancy rates in couples with infertility attributable to oligoasthenospermia alone. Twenty couples were randomized to receive IC-AIH or IU-AIH. Sixty-three insemination cycles were completed. During the same study period, 35 cycles with timed vaginal intercourse alone were assessed. Four pregnancies occurred, all following timed vaginal intercourse. No pregnancies resulted from IC-AIH or IU-AIH. This suggests that neither IC-AIH nor IU-AIH is of benefit when oligoasthenospermia is the cause of infertility. Pregnancies previously attributed to AIH may also have been conceived as a result of vaginal intercourse. This confounding effect on the results of AIH should always be considered.
