Postcoital intra-uterine aspirate--a unique criterion for selecting patients for natural or assisted conception.

ABSTRACT

The success of any infertility management programme is reflected in its efficacy to achieve a pregnancy either spontaneously or through assistance. For this purpose some routine investigations are carried out to pinpoint the nature of problem(s) which an infertile couple is troubled with. As the basic requisite for conception to occur is the accumulation of motile spermatozoa around the egg at the site of fertilisation, proper assessment of sperm transit from the vagina to the tubal ampulla becomes a very important criterion to predict the possibility of spontaneous pregnancy. Till date postcoital test was the sole investigative tool available to serve this purpose but unfortunately it fails to furnish any information about the concentration and nature of quality of spermatozoa beyond the cervix. This results in the disparity between postcoital test results and pregnancy outcome. In the present study intra-uterine fluid was examined along with cervical mucus 4-6 hours postcoitus in the pre-ovulatory period. The objective was to gather information about the fate of spermatozoa subjected to the uterine environment after being vaginally deposited during coitus. The result of this combined test has been found to be very much informative and helpful for the fertility physician to set the criteria for timed intercourse and / or intra-uterine insemination. This simple test thus appears to play a leading role in infertility management in near feature.
