Abstract
We evaluated the effect of in vitro fertilization (IVF) on sexual function in men, particularly for erectile dysfunction. A prospective case-control study at a tertiary medical center. The study group comprised men of infertile couples that required IVF to conceive. The control group comprised men of couples who conceived spontaneously. The effects of IVF on sexual and erectile function were assessed based on the International Index of Erectile Function (IIEF-15) and the Self-Esteem and Relationship (SEAR) questionnaires. Participants were followed up to 1 year postpartum. Compared to the control group (378), for the IVF group (356), mean IIEF-15 scores were significantly lower: prior to pregnancy (31.7±4.5 vs 64.4±7.2, p <0.0001), at mid-pregnancy (37.3±5.1 vs 66.4±5.5, p <0.0001) and up to one year postpartum (42.3±4.9 vs 68.6±4.3, p <0.0001). Compared to the control group, in the IVF group, mean SEAR scores were significantly lower at these 3 respective time points (29.9±6.3 vs 66.5±8.3; 34.1±5.8 vs 66.9±7.2; and 40.9±6.7 vs 67.3±5.6; p <0.0001). At the 3 time points, for the IVF compared to the control group, the median monthly sexual intercourse rate was lower; and both the use of phosphodiesterase-5 inhibitor and psychologist/sexologist care were higher. The prevalence of erectile dysfunction among men participating in IVF in order to conceive is significantly higher compared to couples that conceived spontaneously, thus leading to an extremely high rate of phosphodiesterase-5 inhibitor use.
