title: Prognostic value of postcoital test in unexplained infertility.
abstract: A series of 70 couples with suspected unexplained infertility and who became pregnant after 262 monitored cycles, were reviewed. In each cycle, the postcoital test was scheduled near ovulation time as judged by prior basal body temperature shifts and by cycle length. Postcoital test was graded as excellent, good, fair, bad, and negative. A mean of 26.7% of pregnancy rate per cycle resulted and a mean of 3.74 cycles were needed to obtain a pregnancy. Pregnancy rate was higher (P less than 0.01) for cycles with excellent postcoital test and lower for cycles with bad test. There were no statistically significant differences (P greater than 0.05) in percentage of pregnancies between cycles with either excellent, good, or fair postcoital test. On the other hand, there was statistically significant decrease (P less than 0.05) in the percentage of pregnancies when cycles had bad postcoital test.
