Impact of vasectomy on the sexual satisfaction of couples: experience from a specialized clinic.

Introduction: Vasectomy is the simplest, safest, and most effective form of definitive fertility control in men [1]. Vasectomy is used for 10% of contraception worldwide but only for 2% in Germany [2]. The aim of this study was to investigate the impact of vasectomy on the sexual satisfaction of sterilized men and their partners.

Material And Methods: Vasectomized men and their partners were surveyed by means of the IIEF (International Index for Erectile Function) and the FSFI (Female Sexual Function Index) questionnaires. A total of 294 couples were surveyed; 90 men answered the IIEF, and 74 women answered the FSFI. The results of the questionnaires were compared to a historical comparison group. The men were also surveyed with a not validated questionnaire, which was returned by 95 men. The two-sample t-test for independent samples, the chi-squared test, and the Wilcoxon-Mann-Whitney test were carried out.

Results: The vasectomized men had significantly better results than the healthy historical comparison group in the IIEF domains of erectile function, orgasm, sexual desire, and intercourse satisfaction. For the female partners of the sterilized men, there were almost no significant differences in any questions of the FSFI in comparison to the control group. A significant difference was observed only in the domain 'arousal'.

Conclusions: Vasectomy does not have a negative impact on the sexual satisfaction of the affected couples. In fact, sexual satisfaction improved for the sterilized men, while the satisfaction of the women was not reduced by the vasectomy.
