The Actual State of Sexual Dysfunction in Newlywed Men Starting to Try for a Baby in Japan

We aimed to evaluate the sexual function in newlywed men or men just before marriage to better understand the current situation of the male sexual and reproductive function.

This study included 719 men visiting our hospital or clinic for fertility screening. Patient characteristics including age, sexual status, semen parameters, several symptoms, and blood analysis results were assessed. We compared several factors between patients with sexual dysfunction (SD group) and those with normal sexual function (SN group), and performed univariate and multivariate analyses to identify independent risk factors for sexual dysfunction.

Of 719 men, 139 (19.3%) were identified as having sexual dysfunction, including erectile dysfunction [ED], n = 88 [12.2%]; ejaculatory dysfunction, n = 66 [9.1%]; and decreased libido, n = 35 [4.9%]. Significant differences between the SD and SN groups were observed in age, albumin, liver enzymes, triglycerides, blood sugar, and semen volume. In a multivariate analysis, only age, body mass index, and the Beck Depression Inventory score for depression remained significant risk factors for sexual dysfunction.

It was considered that men who are older, obese, or exhibit depressive symptoms are likely to experience sexual dysfunction before the initiation of fertility treatment.
