Evaluation of high vaginal insemination at oocyte recovery in patients undergoing in vitro fertilization

Abstract

The value of high vaginal insemination at the time of oocyte recovery for in vitro fertilization (IVF) has been assessed. A previous study reported a dramatic increase in the incidence of pregnancy in women after high vaginal insemination (53%) compared with those without insemination (23%). Of 306 patients undergoing IVF, 97 (32%) became pregnant and 20 (21%) miscarried. Those patients with tubal damage numbered 187. Sixty (33%) became pregnant and 10 (17%) miscarried. The data were assessed according to the numbers of conceptuses replaced, the age of the patient, and whether a spontaneous luteinzing hormone surge or human chorionic gonadotropin was a trigger for ovulation, each with a significant effect on the outcome of treatment. No significant effect of the use of high vaginal insemination was found.
