The combined prevalence of minimal, moderate, and complete ED is approximately 40 percent in males at age 40, and reaches nearly 70 percent by 70 years of age. The rapid increase in blood volume fills the erectile chambers, and the increased pressure of the filled chambers compresses the thin-walled penile venules, preventing venous drainage of the penis.

In males, FSH and LH work together to trigger their testes to begin producing testosterone. As puberty approaches (usually between ages 10 and 14), the hypothalamus produces gonadotropin-releasing hormone (GnRH), which triggers FSH and LH. These hormone levels peak midpregnancy as the first ovarian follicle or seminiferous tubule (coiled tubules within the testes) mature in the fetus. Hormones are chemicals that coordinate different functions in your body by carrying messages through your blood to your organs, muscles and other tissues.|In addition, a continuous increase in vaginal sexual arousal may result in higher genital sensations and sexual appetitive behaviors.
