New studies have confirmed that a new experimental penis spray when applied five minutes before sex helps men to overcome problems of premature ejaculation.

The ingredients of the spray called, PSD502, are anesthetics lidocaine and prilocaine. It, however, does not numb the feeling because of the presence of a special ingredient in the spray which allows it to penetrate quickly under the skin, says Ira Sharlip, MD, clinical professor of urology at the University of California, San Francisco.

The drug is considered to be safe for the female partners as well as for men themselves. The percentage of women who reported decreased feeling in the vagina is as low as 5%.

Sharlip says, "There is some burning sensation in the vagina in about 5% of partners, it infrequently causes problems in female partners because it is absorbed so quickly there is little left on the skin. The risk of transfer is small."

Sharlip was among the three investigators who presented the studies of PSD502 at theis week’s meeting of the Sexual Medicine Society of North America Inc. in San Diego.

The results of the studies clearly show that men are able to postpone ejaculation about five times longer. These findings confirm those of a previous study done earlier this year.
