The Science Behind Female Ejaculation

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.

Excuse me? Farts cause erections…?

According to the article, Fart molecule could be next Viagra published in New Scientist, rats injected with an enzyme that produces hydrogen sulfide in human penises caused erections in the randy little critters. Hydrogen sulfide (H2S) smells like bad flatulance and rotten eggs.

Hydrogen sulfide relaxes blood vessels in the same way as Nitric oxide (NO). Erections occur because the arteries relax and allow blood to flow into the erectile tissue (corpora cavernosa).

What will they come up with next?

Masturbation can be good for the over-50s

A recent UK Independent article Masturbation can be good for the over-50s, reported on a study published in the British Journal of Urology International that showed a link between masturbation and increased risk of prostate cancer. The study examined the sexual habits of men diagnosed with prostate cancer under the age of 60 against a control group. Younger men engaging in sexual activity (sex and masturbation) at least 20 times a month appear to be at an increase risk of prostate cancer. Interestingly, the risk decreased in men over 50 who engaged in sexual activity at least 10 times a month.

The researchers have no explanation as to why masturbation, as opposed to sexual intercourse, is a marker for increased risk of prostate cancer. Seems like men of any age should just relax and enjoy themselves…by themselves or otherwise.
