Viagra, Levitra, and Cialis May increment degrees of the Reproductive Hormone Oxytocin
Aug. 27, 2007 — New research shows that erectile dysfunction drugs such as Viagra, Levitra, and Cialis may increase production of oxytocin, a reproductive hormone released during orgasm.
That intelligence arrives from men of science at the University of Wisconsin at Madison.
They tried out sildenafil (Viagra’s active element), vardenafil (Levitra’s active element), and a related chemical known as T-1032 in lab tests on rats.
The investigators open part of the rats’ pituitary gland to those chemicals (which are called PDE5 inhibitors) and to mild electric stimulation. Below those circumstances, the rats’ pituitary glands brought on a lot of oxytocin.
Causes that occur in people, too? This analyse does not answer that question.
But that issue deserves further analyse, since oxytocin is significant in several reproductive functions, write researcher Meyer Jackson, PhD, and colleagues.
Their study expresses no signs of increased oxytocin production without stimulation.
“Erectile dysfunction drugs do not induce erections impromptu; they enhance the response to sexual stimulation,” Jackson states in a news release.
“The same thing is happening in the [rats’] posterior pituitary — Viagra won’t induce the release of oxytocin on its own, but it will raise the amount of expiration you get in response to electrical stimulation,” states Jesse Jackson Technorati Profile
