Background: The relationship between intramural myomas and fertility remains unclear. The main debate rests on whether cavity-distorting intramural myomas (CDMs) adversely affect fertility more than non-CDMs. We aimed to compare the effects of enucleating non-CDMs and CDMs on fertility improvement in females with unexplained infertility.
Methods: We prospectively recruited 83 women undergoing myomectomy for unexplained infertility with intramural myomas between June 2008 and November 2012 and classified them into non-CDMs group (n = 45) and CDMs group (n = 38). We then compared postoperative infertility rates, spontaneous pregnancy rates, pregnancy outcomes, live birth rates, and obstetric complications. For continuous variables, we calculated the mean ± standard deviation, median and interquartile range, and analyzed the data using Student's t-test and the Mann-Whitney U-test. For categorical variables, the Pearson's Chi-square test, the continuity correction test, and Fisher's exact test were used.
Results: Patients' demographics and myoma characteristics were comparable between the two groups. The overall spontaneous pregnancy rate increased from 0% to 68.42% following myomectomy. The postoperative infertility rate was significantly higher in the non-CDMs group than that in the CDMs group (50.00% vs. 23.53%, t = 5.579, P = 0.018), whereas the postoperative spontaneous pregnancy rate was significantly lower in the non-CDMs group than that in the CDMs group (47.62% vs. 70.59%, t = 4.067, P = 0.044). Compared with the enucleation of non-CDM, the enucleation of CDM patients was a protective factor for the fertility restoration (risk ratio [RR] = 3.717, 95% confidence interval [CI]: 1.284–10.753, P = 0.015), although postoperative fertility restoration declined with age (RR = 1.141, 95% CI: 1.005–1.295, P = 0.041).
Conclusions: Intramural myomas are associated with impaired fertility. Women experiencing unexplained infertility, and possessing intramural myomas, have a better chance of conception following myomectomy, and these benefits are more obvious for younger patients and patients with CDM.
