Impact of infertility duration on male sexual function and mental health.

Our study is the first time to use the infertility duration as an independent variable and group this variable to analyze its impact on the sexual function and mental health of men from infertile couples comprehensively and systematically. The increased infertility duration is an independent risk factor for the occurrence of sexual dysfunction but not for mental disorders. In the process of infertility treatment, sexual health and mental health cannot be ignored, especially for patients with prolonged infertility.
