Is Female Orgasm Important for Baby Making Sex?

The female orgasm is not required for baby making, and plenty of women conceive without it. But could it help? The research isn’t clear, but some studies indicate it just may give sperm a boost. One theory is that female orgasm helps move the sperm up from the cervix to the fallopian tubes. Another is that orgasm makes you feel sleepy, which increases your odds of remaining horizontal after sex.
