Why do your muscles contract and pulse during an orgasm (specifically women)?

853 viewsBiologyOther

During orgasm, the muscles in the genital area contract and pulse, I know it’s pelvic floor muscles.. What I don’t understand is WHY they do that during orgasm. I believe it’s a release of tension or what have you… But why do other muscles of the body not contract, pulse, and feel pleasurable to that extent when they experience relief of tension?

Some research suggests the contraction of the pelvic muscles might help introduce semen to the cervix more directly and aid in conception, but it could just be one of those “just because” things.

First of all, the main reason for the contractions is to facilitate ejaculation.

Second, there is enough similarity between male and female genitalia that these contractions are also present in females, even though they don’t need to ejaculate. I guess you could say evolution didn’t bother to prevent females from experiencing muscular contractions during orgasm as well because there was no motivation to eliminate it.

They are similar because if you learn about how genitalia is formed in a fetus, they start off the same but diverge to form the male or female genitalia that we are familiar with. If you want to read more about how genitalia is formed, look up Genital Tubercle.

Things are the way they are because of evolution. But that doesn’t mean everything has a “purpose.” The other answers have provided the main reasons people think it happens, to facilitate getting the sperm to the egg. But I just wanted to make the point that there of lots of unnecessary and redundant things that evolved in the human body that are there simply because they don’t cause too many problems, so there’s no pressure for evolution to get rid of them.

That would be the cervix Contracting’s to get closer to the sperm pooling outside it. Dipping in the pool to enhance the chance of pregnancy!

lol I sound like some kind of orgasm expert!

“X” is an unknown value

“SPURT!” Is a drip under pressure!

I’ve seen some videos of the cervix during orgasm from a study done in Europe that shows the cervix throbbing and actually pulsating to allow for more semen to enter the uterus. The muscle almost dips into the ejaculated for more sperm uptake.

Have never looked into this, but isn’t there a release of oxytocin? That is a hormone that also stimulates muscle contractions during labor.

I saw a documentary about sex when I was younger but I don’t think it was for younger kids, but I remember it showing when a woman orgasms the muscle “dips” down into the semen and slorps it up. The visual of the dip and slorp will never leave me

I think someone already said it, but it’s definitely to move fluid… In the male, the muscles contract and relax to pump out semen… In the woman they do the same thing to move the semen up the virginal canal …

Your body needs a reward system for beneficial behavior, and there are only a few limited things that your body can do that feels good.

The pleasure specifically is thought to be a motivator for women to engage in sex. Without it, sex would be pretty awful for women, getting your insides pounded and such. One of the bits of evidence for this is that females in a species (I believe the study was on cats) were more likely to copulate the closer their clitoris was to their vagina (and therefore more likely to be stimulated during the act).
