Kegel exercises strengthen the pelvic floor muscles that power orgasmic contractions and control ejaculation, and by increasing voluntary control over those muscles some people—particularly men—can le...
Laboratory studies define the female orgasm using a range of physiological markers—vaginal blood flow/engorgement, pelvic and uterine muscle contractions, and neuroendocrine changes such as prolactin ...
The most consistent and replicated neuroendocrine change after orgasm in women is an elevation in plasma prolactin that is orgasm-dependent and typically sustained for about an hour; other candidate h...
Objective physiological markers that cluster around female orgasm include rhythmic increases in pelvic and anal EMG activity, correlated cardiovascular changes (especially systolic blood pressure and ...
