โDoctors used to prescribe orgasms for fertility: In the early 1900s, many gynecologists believed in the sperm retention, or โup suckโ, theory. This theory stated that when a woman had an orgasm, the contractions in her vagina helped move the sperm closer to the egg and thereby increase the odds of conceiving. However, a study in the 1960โs indicated that orgasm doesnโt actually increase the chances of conception in humans.โ
