Now, a new study brings an interesting new theory into the mix: In a literature review recently published in the Journal of Evolutionary Zoology, a pair of developmental evolutionary specialists posit that as the female reproductive system evolved, so did the role of the orgasm. But similar to vestigial organs like tonsils or appendix, the orgasm remained. The secret lies in ovulation, the mechanism that causes ovaries to discharge eggs for reproduction. In some species, like cats and rabbits, physical stimulation is needed to prompt the egg to be released—a phenomenon called induced ovulation. But in humans, ovulation happens spontaneously without stimulation , often on a regular schedule.

Trying to conceive Do orgasms help you get pregnant? But do women? We asked the experts whether achieving climax can help with conception. May 22, Photo: Stocksy A few years ago, I ran a mommy-and-baby group once a month in Toronto. The number of participants ebbed and flowed, depending on the subject of the meeting—everything from sharing birth stories to returning to work after mat leave—but no theme got a better turnout than sex.
Can A Woman’s Orgasm Increase Chances Of Pregnancy?
March 8, The ovaries and fallopian tubes mostly just hang out quietly in the pelvis, minding their own business, and the uterus only expands with pregnancy and is happy to shrink back to normal size after the baby is gone. But as David Elad of the Department of Biomedical Engineering at Tel Aviv University, Israel, has recently discovered, the uterus, like everything else on Earth, is subject to the laws of motion. Understanding those movement, Elad points out, can also have a major impact on the success or failure of in vitro fertilization and the possibility of successful pregnancies for infertile couples.
The reasons for the interest in female ejaculation have been questioned by feminist writers. De Graaf In the 17th century, the Dutch anatomist Reinier de Graaf wrote an influential treatise on the reproductive organs Concerning the Generative Organs of Women which is much cited in the literature on this topic. De Graaf discussed the original controversy but supported the Aristotelian view. In the lower part, near the outlet of the urinary passage, this membrane is pierced by large ducts, or lacunae, through which pituito-serous matter occasionally discharges in considerable quantities. Between this very thin membrane and the fleshy fibres we have just described there is, along the whole duct of the urethra, a whitish membranous substance about one finger-breadth thick which completely surrounds the urethral canal
