The value of the postcoital test in predicting the fertilization of human oocytes

Abstract

The relevance of the postcoital test (PCT) in relation to the fertilization rate of oocytes was determined in an analysis of 66 couples in an in vitro fertilization (IVF) program. The test is routinely performed in the workup of all IVF patients and is accurately timed to the immediate preovulatory period by daily hormonal; cervical mucus, and ultrasound monitoring. Cases demonstrating antispermatozoal antibodies in the serum of either partner, in cervical mucus, or in semen were excluded. There was no significant difference in the fertilization rate of oocytes whether the PCT result was negative, equivoral, or positive, and the finding was the same in both normospermic and oligospermic groups. It is concluded that the PCT is of no value in predicting the outcome of IVF and, conversely, IVF should be considered as a therapeutic option for couples with a negative PCT.
