Proper discussion and research on female sexuality and in particular, female ejaculation has been a long time coming. Female ejaculation is often dismissed as myth and mainly attributed to loss of bladder control at the time of orgasm. This is of course still true for some cases, but not all.
Laboratory analysis of fluid expelled from a small group of females who claim to experience female ejaculation tells a different story. A recent report, Everything you always wanted to know about female ejaculation (but were afraid to ask) in New Scientist describes how researchers found significant quantities of the protein prostate-specific antigen (PSA) present in in the fluid. Prostate cells in the male prostate gland produce PSA which is present in serum and semen.
Ultrasounds of the women who experienced female ejaculation showed evidence of a structure surrounding the urethra that is similar to the male prostate gland. The area of the female prostate is located near the G-Spot and is most sensitive to sexual arousal. It appears that stimulating the G-Spot also stimulates the female prostate resulting in ejaculation.
