This study compares the outcomes of ART treatments in single women and women in lesbian relationships. The results show that there is no significant difference in live birth rate and cumulative live birth rate between the two groups, when adjusted for age, regardless of whether using donor sperm for IVF or IUI treatments.
Purpose Assisted reproductive technology (ART) treatments with donor sperm have been allowed for women in lesbian relationships (WLR) since 2005 in Sweden, but for single women (SW), these became approved only recently in 2016. This study was conducted to compare the outcomes of ART treatments in SW vs. WLR. Methods This is a prospective controlled cohort study of 251 women undergoing intrauterine insemination (D-IUI) or in vitro fertilization (D-IVF) using donor sperm between 2017 and 2019 at the department of Reproductive Medicine, Karolinska University Hospital. The cohort comprised 139 SW and 112 WLR. The main outcomes included differences in live birth rate (LBR) and cumulative live birth rate (cLBR) between the groups. The SW underwent 66 D-IUI and 193 D-IVF treatments and WLR underwent 255 D-IUI and 69 D-IVF treatments. Data on clinical characteristics, treatment protocols and clinical outcomes were extracted from the clinic's electronic database. The outcomes of D-IUI and D-IVF were separately assessed. Results The cohort of SW was significantly older than WLR (37.6 vs. 32.4 years, P < 0.001), and more commonly underwent IVF at first treatment (83% vs. 29%, P < 0.000). Conversely, WLR underwent more frequently D-IUI as a first treatment (71% vs. 17% of SW, P < 0.001) and more often in the natural cycle (89.9% vs. 70.8%, P = 0.019), respectively. There was no statistically significant difference in the main outcome LBR between the two groups, or between the two different types of treatment, when adjusted for age. Perinatal outcomes and cLBR were also similar among the groups. Conclusions SW were, on average, older than WLR undergoing treatment with donor sperm. No significant differences were seen in the LBR and cLBR when adjusted for age between the two groups and between the two types of treatment (D-IVF vs. D-IUI).
