Frequently Asked Questions and Articles on Sex

If you’re female, is sex healthy?
A wide range of psychological and physiological health factors benefit from penile-vaginal intercourse, but other sexual activities don’t seem to provide the same benefits, and masturbation and anal intercourse might even be detrimental to health. (Sorry.)
Do herbal aphrodisiacs work?
It depends on the product touted to be an aphrodisiac, but some of them do apparently increase sexual desire; it is a relatively under-researched topic though, and we don't know why they increase sexuality.
Is semen high in protein?
Yes. Semen is 50% protein by weight and contains a variety of nutrients to protect the sperm cells from damages.
Does ejaculation affect testosterone levels?
Ejaculation results in changes in prolactin (increase) and dopamine (temporary decrease), but does not result in changes in testosterone. Although prolactin and dopamine are both involved with testosterone, they do not appear to influence testosterone levels acutely.
