A marked decline in sexual activity has been reported in stroke patients. Little information, however, is available on clinical correlates of sexual dysfunction, changes in the sexual life of spouses of stroke patients, and abnormalities of nocturnal penile erections.
In this prospective 6-month follow-up study, we assessed the impact of stroke on libido, sexual arousal, coital frequency and satisfaction with sexual life in 50 stroke patients (38 men, 12 women, aged 32 to 65 years) and in their spouses. We also measured nocturnal penile erections of the male patients using a strain gauge attached around the penis.
All the analyzed aspects of sexuality, i.e., libido, coital frequency, erection, ejaculation, vaginal lubrication, orgasm and satisfaction with sexual life, were commonly decreased as a consequence of stroke both in the patients and in their spouses. Fourteen (28%) patients at 2 months post-stroke and 6 (14%) patients at 6 months had ceased having sexual intercourse. Nocturnal erections at 2 months post-stroke were normal in 17 (45%) of the 38 male patients and impaired in 21 (55%) patients, but all of the patients had some nocturnal erections. Sexual dysfunction correlated significantly (P<0.05) with the presence of the sensory hemisyndrome.
Sexual dysfunction and dissatisfaction with sexual life seems to be common both in male and female stroke patients and in their spouses. Decreased libido, sexual arousal and satisfaction are related particularly to the presence of the hemisensory syndrome. The etiology for sexual dysfunction after stroke is multifactorial including both organic and psychosocial factors.
据报道，中风患者的性活动显著下降。然而，关于性功能障碍的临床相关因素、中风患者配偶性生活的变化以及夜间阴茎勃起异常的信息却很少。
在这项为期6个月的前瞻性随访研究中，我们评估了中风对50名中风患者（38名男性，12名女性，年龄32至65岁）及其配偶的性欲、性唤起、性交频率和性生活满意度的影响。我们还使用附着在阴茎周围的应变仪测量了男性患者的夜间阴茎勃起情况。
中风导致患者及其配偶的所有被分析的性方面，即性欲、性交频率、勃起、射精、阴道润滑、性高潮和性生活满意度普遍下降。中风后2个月有14名（28%）患者、6个月有6名（14%）患者停止了性交。38名男性患者中，17名（45%）在中风后2个月的夜间勃起正常，21名（55%）患者受损，但所有患者都有一些夜间勃起。性功能障碍与感觉性半身综合征的存在显著相关（P<0.05）。
性功能障碍和对性生活的不满在男性和女性中风患者及其配偶中似乎都很常见。性欲、性唤起和满意度的下降尤其与半身感觉综合征的存在有关。中风后性功能障碍的病因是多因素的，包括器质性和心理社会因素。
