Endometrial histology after first trimester spontaneous abortion.

The endometrial histology after spontaneous abortion was investigated by performing an endometrial biopsy in the two menstrual cycles subsequent to miscarriage in 12 women. In the first cycle, 66% (8/12) of the biopsies had the following abnormalities: (1) proliferative endometrium (n = 4), (2) proliferative glands and decidualized stroma (n = 1), (3) endometritis (n = 1), and (4) luteal insufficiency (n = 2). In the second cycle, 20% (2/10) of the biopsies demonstrated luteal insufficiency. Forty-five percent (10/22) of the first two cycles after spontaneous abortion demonstrated abnormal endometrial histology, with the first appearing more abnormal than the second (P = 0.06). Two conceptions occurred during the study period; both were uneventful term pregnancies. These findings suggest that a large proportion of the first two menstrual cycles after spontaneous abortion and curettage are abnormal, with the first cycle being more frequently abnormal than the second.

A randomized, controlled trial of clomiphene citrate and intrauterine insemination in couples with unexplained infertility or surgically corrected endometriosis.

This study was initiated to test the hypothesis that treatment with clomiphene citrate (CC) and intrauterine insemination (IUI) results in increased fecundity when compared with periovulatory intercourse in couples with either unexplained infertility or surgically corrected endometriosis. Sixty-seven couples entered a randomized, prospective trial comparing CC/IUI with observation. During the study, there were 14 pregnancies in 148 treated cycles (fecundity = 0.095) compared with 5 pregnancies in 150 untreated cycles (fecundity = 0.033). Using life-table analysis and the log-rank test, the difference in fecundities was statistically significant. Pregnancy outcome was not significantly different between the two groups. When comparing conception with nonconception cycles during treatment, no differences between the size of the lead follicle or the number of dominant follicles was detected. We conclude that treatment with CC/IUI improves fecundity in couples with unexplained infertility or surgically corrected endometriosis.
