It doesn’t matter what position you’re in—reverse cowgirl, missionary, standing, whatever. Sperm + egg + sticking to the uterus = pregnancy.
For a little refresher on the birds and the bees—without the corny euphemisms—check out our newest Provider Perspective, “Pregnancy 101.”

The clitoris is pure in purpose. It is the only organ in the body designed purely for pleasure. The clitoris is simply a bundle of nerves: 8000 nerve fibres, to be precise. That’s a higher concentration of nerve fibres than is found anywhere else in the body, including the fingertips, lips, and tongue, and it is twice the number in the penis. Who needs a handgun when you’ve got a semiautomatic.

Natalie Angier (via scrapparchment)

Pretty incredible, huh? In case you’re looking for ways to make the most of that “semiautomatic” pleasure center, we’ve got a Frisky Friday on 5 secrets of highly orgasmic women that could be of interest…

i-am-mario:

Get educated on sperm!

Interesting information!
*not all men have penis/can produce sperm 

That’s right, folks—sperm move faster than a jaguar and can live in the female reproductive tract for up to 5 days… This is why we keep going on and on about birth control.

The Magical Powers of Semen...

New research on β-NGF, a protein found in semen, suggests that it may be able to trigger ovulation. Scary or fascinating?

Semen is not only nutritious, but it also has a wonderful texture and amazing cooking properties. Like fine wine and cheeses, the taste of semen is complex and dynamic. Semen is inexpensive to produce and is commonly available in many, if not most, homes and restaurants. Despite all of these positive qualities, semen remains neglected as a food.

That’s the blurb on the back of the cookbook Natural Harvest: A Collection of Semen-Based Recipes by Fotie Photoenhauer, discovered thanks to this Frisky article.

Would you try it?

Flatworms are hermaphrodites, meaning they have both male and female sex organs, which triggers some seriously odd reproductive behavior. When trying to impregnate another worm, for example, a flatworm tries to pierce the skin of the other using its penis. Experts term this heated competition “penis fencing”: The first to successfully impregnate the other while fending off advances becomes the de facto male, who wins because he won’t have to expend the energy required to carry eggs.

From “The 9 weirdest animal penises on Earth,” posted to The Week on June 22nd, 2012.

Whoa. This brings fighting as foreplay to a whole new level…

Patients almost always have the same look on their face when we talk about ovarian cysts. It’s that look of, ‘OMG, I have a ticking time-bomb in my pelvis!’ I worry that they imagine a giant green blob growing larger and larger inside them, like a Chia pet, that might one day suddenly explode.

The good news is that this imaginative view of an ovarian cyst is far worse than the reality. Many women will have an ovarian cyst at some point in their lives, and most won’t even know it.

Wondering what ovarian cysts have to do with birth control? Check out our latest Provider Perspective, “Ovarian cysts: No biggie, but birth control can help,” to find out…

Insects and sex (from yesterday’s birth control reminder): Male bush cricket testicles are 14% of their body weight. That’s like a 200 lb. dude with 28 lb. testicles.

Fun Fact of the Day:

thecsph:

Did anyone know that dolphins have sex for pleasure. Looks like 9 year olds aren’t the only ones enjoying themselves at Sea World! 

That is fun.

There are a ton of mood-enhancing chemicals in semen and the vagina can absorb them. Cortisol increases affection. Estrone and Oxytocin elevate mood. Prolactin and Thyrotropin-releasing hormones are natural antidepressants. Melatonin helps regulate sleep. And Serotonin makes you feel happy. But please don’t try to fight depression with it. It doesn’t quite work like that.
Who says Sundays can’t be frisky? Check out our latest Frisky Friday to read more about the fascinating properties of semen.
