Fertility and pregnancy outcomes in patients with bicorporeal uterus and blind hemivagina: 20 years of experience in a tertiary referral gynaecological department

Abstract Background To evaluate fertility and pregnancy outcomes in patients with uterus bicorporeal and blind hemivagina. Our second objective was to investigate factors predicting fertility and pregnancy outcomes in those patients. Material and methods We conducted a retrospective analysis in a tertiary referring gynaecological department, in France. We included all patients with uterus bicorporeal and blind hemivagina who underwent at least one surgery in our centre. Initial characteristics of the patients included were extracted from their medical charts and patients were contacted to assess their fertility and pregnancies outcomes upon their consent to participate to the study. Results Between 1989 and 2010, 79 patients fulfilled inclusion criteria and were selected for analysis. Mean follow up of those patients was of 16.15 (QI 10–21) years. Forty-six patients (58.2%) returned the survey and among them, 21 (45.7%) were fertile, 8 (17.4%) were infertile and 17 (37%) never attempted to get pregnant following initial management. Forty-nine pregnancies were included to assess pregnancies outcomes: 11 (22.5%) early miscarriages, 1 (2.0%) extra-uterine pregnancy, 2 (4.1%) second semester miscarriages and 35 (71.4%) leaded to living birth. Nineteen (54.3%) deliveries occurred by caesarean section and 14 (40.0%) by vaginal delivery. Fifteen pregnancies (42.9%) were complicated. In univariate analysis, adhesiolysis performed at the time of initial surgery was the only factor associated with infertility (p = 0.004). Conclusions Fertility seems to be perfectly conserved in those patients and they do not have increased rate of adverse pregnancies outcomes.
