Fertility outcomes following myomectomy in an urban hospital setting.

OBJECTIVE: Infertility is rarely a consequence of myomas. However, a causal relationship may be suspected when other causes of infertility have been excluded. Uterine myomas have been reported in 27% of infertile women; 50% of women with unexplained infertility become pregnant after myomectomy. The objective of this study was to establish the impact of the surgical removal of myomas on fertility outcomes in women experiencing recurrent pregnancy loss or unexplained infertility. Fallopian tube, anovulatory disorders and male fertility factors had been appropriately excluded. DESIGN: This was a retrospective study in which we compiled data from the medical records of eight patients from 2003-2004 who underwent abdominal myomectomy for infertility or recurrent pregnancy loss. We calculated rates for subsequent spontaneous abortion, preterm delivery, cesarean delivery, malpresentation and postpartum hemorrhage. RESULTS: There were two patients who were nulliparous premyomectomy, and six had recurrent pregnancy losses. There was a cumulative success rate of 75% (six live births in eight patients) following myomectomy. One had two subsequent pregnancies. There were no spontaneous abortions. Three (37.5%) patients failed to conceive postmyomectomy, one of which was found to have bilateral tubal occlusion. Of the six pregnancies achieved, two (33%, 95% CI 2.06, 3.14) were preterm deliveries, six (100%, 95% CI 1.74, 3.50) were delivered by cesarean section and three (50%, 95% CI 3.50, 1.73) were malpresentations (two breech, one transverse lie). One patient (16%, 95% CI 2.06, 3.30) had abruptio placentae and two patients (33%, 95% CI 2.06, 3.14) experienced postpartum hemorrhage. CONCLUSION: This study suggests that there may be a beneficial effect of surgical removal of myomas on enhancing fertility and successful pregnancy outcome. However, the sample was too small to achieve statistical significance.
