title: Characteristics and clinical outcomes of patients undergoing fertility treatment by double gamete donation.
abstract: The number of women receiving in vitro fertilization cycles with both oocyte and sperm donation (double donation; DD) has grown globally in the last decade. The aim of this retrospective study, which included 1139 DD cycles, was to describe the characteristics of patients receiving DD and the outcomes of this assisted reproductive treatment. A cluster analysis identified couple 'status' as the main variable in dividing patients into categories. Three such status groups were identified for further analysis: (i) single women (SW), that is women without a partner either male or female; (ii) women with a male partner (MP); (iii) women with a female partner (FP). SW were significantly older (43.9) than patients with a MP (40.4) and a FP (41.3). Women with a male or FP comprised fewer patients with no previous assisted reproductive technology cycles (18.4% and 25.7%, respectively) compared to SW (43.5%). The proportion of patients without children before treatment was significantly different between SW (94.7%) and women with a MP (87.2%). There were no differences in clinical outcomes among the three groups studied. Biochemical pregnancy rate was 58.2% in SW, 58.4% in women with a MP and 64.9% in women with a FP. For the same groups, clinical pregnancy rates were 50.2%, 49.4% and 55.4%, while 'take-home baby' rates were 36.6%, 38.9% and 40.3%. Multiple birth and caesarean section rates were not different among the groups, with twinning rates 21.1%, 30.4% and 36%, and caesarean section rates 25.6%, 24% and 26.4% for SW, women with MP and women with FP, respectively.
