Ananova:  
Women more likely to have sex when fertile

Women are much more likely to have sex during the fertile
part of their monthly cycle, says new research.

Allen Wilcox, a US reproductive epidemiologist who led the
study, said: "If you're a couple trying to get pregnant, that's
great news. There's a hidden biological process working in
your favour."

The work also indicates that having unprotected sex once is
more likely to result in pregnancy than previously thought.

"If you are not trying to pregnant the news is not so good,"
Wilcox told New Scientist.

There has been plenty of anecdotal evidence that couples
were friskier at the fertile time of the month but research
tended to focus on couples who were trying to conceive.

Wilcox's study focused on 68 sexually-active women who
were using birth control.

Even though the women had no plans to have a baby, they
were 24% more likely to have sex in the six days leading up
to ovulation, the most fertile time of their menstrual cycle.

Wilcox's team also discovered couples were most likely to
have sex at weekends, presumably because the working
week is not as accommodating to romantic plans.
