"O-Shot™" May Improve Female Sexual Response

LA JOLLA, Calif., Jan. 17, 2012 /PRNewswire/ -- Using growth factors derived from a woman's own blood, physician researchers Drs. Samuel Wood and Charles Runels have developed a simple, office-based procedure that appears to markedly improve the quality of a woman's sexual response. The preliminary results of this procedure, which involves the injection of platelet-derived growth factors (PDGFs) into a specific area on the upper wall of the vagina and the clitoris, were recently presented at the annual meeting of the A4M, the largest regenerative biomedicine convention in the country.

"The most important factor in the success of this procedure is the correct placement of the injections. When these same growth factors were injected into the putative 'G-Spot,' we saw minimal or no improvement in sexual function, but when injected into an area distinct from the traditionally defined G-Spot, the response has been surprising, robust and consistent," said Dr. Wood.

"This area of responsiveness is distinct enough from the ill-defined 'G-Spot' that we felt it deserved its own name. The name we chose is the 'O-Spot' ("Orgasm Spot™') and we have termed the procedure involving the injection of growth factors into this area the 'O-Shot' (Orgasm Shot). This area appears to be critical in determining whether a woman is able to achieve a vaginal orgasm, something experienced consistently by fewer than 20% of women," explained Dr. Runels.

"It is important to note that there are many potential causes of sexual dysfunction, which affects an estimated 40% of all women, and so all patients should receive a complete evaluation prior to receiving this or any other treatment. Based on over 20 years of research on the use of PDGFs for other medical conditions, the administration of PDGFs appear to safe, and with the use of a local anesthetic the O-Shot itself is associated with minimal discomfort. But because it has not been yet been studied in a comprehensive way, all women should undergo this procedure only as part of a clinical research trial." noted Dr. Wood.

"We recognize that this data is preliminary and must be confirmed by rigorous scientific research before making it widely available to patients. We are now initiating a multicenter clinical trial to definitively examine the effectiveness of this procedure. We are currently adding additional collaborating physicians to the study and are open to considering other candidates. Acceptance criteria include having an excellent understanding of female anatomy, being highly skilled at performing precise medical procedures and having an outstanding reputation among their peers," said Dr. Benito Villanueva, Medical Director at La Jolla Centre for Sexual Health and O-Shot™ Director of Physician Training.

The O-Shot is one of several procedures that involve using platelet-derived growth factors to non-invasively treat common medical problems. The first such procedure was the "Vampire Facelift," which has been featured in numerous diverse media outlets including the New York Times, and the television shows "Dr. Oz" and "The Doctors."

Samuel Wood, M.A., M.D., Ph.D., M.B.A. is a renowned reproductive endocrinologist and stem cell scientist. He is the medical director of Reproductive Sciences Center and the Scientific Director at La Jolla Centre for Sexual Health. He has been featured in numerous print and broadcast media stories and is a listee in Marquis "Who's Who in America" and "Who's Who in the World."

Charles Runels, M.D. is a cosmetic physician, best-selling author and the inventor of several PDGF-based therapies including the "Vampire Facelift."

Benito Villanueva, M.D., has been practicing medicine for over 20 years and has developed a sterling reputation in the field of sexual health and treatment. He is the Medical Director of La Jolla Centre for Sexual Health.
