Differences in female and male perception of information and decision-making in single-embryo transfer in in vitro fertilization in Sweden

The aim of this study was to evaluate the information and the factors that contribute to the decision to accept and choose single embryo transfer (SET) in females and males. Fifty-four females and males undergoing SET were interviewed separately using a structured questionnaire. The women were significantly more satisfied with the information than the men (odds ratio 3.3), but the decision to accept SET was nevertheless more difficult for women (OR 3.1). Only one-third of both female and males were aware of the increased maternal risks with twin pregnancies. There was a tendency that the women who accepted SET had previous children, shorter duration of infertility, and were younger. Cryopreservation of embryos and a good pregnancy chance were important irrespective of gender. The female needs more support to choose SET. The male needs better information and further involvement in decision-making. The females were more aware of the fetal risks, but the awareness of the increased maternal risks with twin pregnancies was low.
