Women's desire for sex linked to hormonal levels
SANTA BARBARA, Calif., April 26 () -- U.S. scientists have confirmed what many women and researchers have long suspected -- a woman's libido has a lot to do with her hormones.Lead author James Roney, a professor at the University of California, Santa Barbara, and colleagues demonstrated hormonal predictors for sexual desire.The findings, published in the journal Hormones and Behavior,[url=http://www.leedpe.com/]cheap christian louboutin shoes[/url], found when hormone levels and sexual desire were factored against the menstrual cycles of undergraduate students,[url=http://www.leedpe.com/]christian louboutin pigalle[/url], the researchers observed a measurable increase in progesterone levels at the same time the subjects noted decreases in sexual motivation.When a woman's cycle is high in estrogen she might feel a greater desire for sex, but when the cycle has higher levels of progesterone -- the second half of the menstrual cycle -- this hormone has a desire-deadening affect.Roney noted the findings don't present a full model, and he'd like to replicate his results with women of different age groups."Undergraduate [women] might be unique for a lot of reasons," he said. "Their hormone levels tend to be a bit different from those of women even just a little bit older. And married women in their 30s are likely to be more consistently sexually active, and that might change the patterns in some ways."
