There are some questions in life that you just’re higher off not understanding the reply to — like how scorching canines are made, or what’s actually in beef jerky. But when you’re one in every of the 27,100 folks googling, “Why is the penis mushroom formed?” per thirty days, you deserve an evidence. Trust, the reply is far more unhinged than you in all probability suppose.

According to evolutionary theories, some penises are formed with their signature mushroom-like head due to what’s referred to as the semen displacement speculation. This speculation suggests the mushroom form can scoop out different males’s semen from the vagina. (Yes, you learn that proper.)

It’s all based mostly on the concept that males in the end wish to be the one to impregnate their companion and that having the ability to scoop out different males’s semen throughout intercourse with their in-and-out thrusts will increase that chance.

New Jersey-based urologist Anika Ackerman, MD, says that the semen displacement principle is a results of “evolution and male competitors” and was studied by researchers in 2003. The researchers used a silicone vagina and a latex penis to imitate intercourse. They have been capable of show that “the form of the penis allowed it to scoop out a semen-like substance,” says Dr. Ackerman. She provides that 90 % of the cornstarch and water combination (the makeshift semen) was eliminated with only one thrust.

Dr. Ackerman says this research validated the displacement principle because it proved a man’s coronal ridge (aka the head of the penis that shapes into the mushroom) would drag out different males’s semen and permit their very own to stay once they’re completed.

Though this can be laborious to consider, and actually, it simply seems like misogynistic BS, intercourse researcher Sarah Melancon

, PhD, says it is a actual evolutionary principle. But it isn’t rooted in one hundred pc truth. She explains that there are loopholes, particularly if you take a look at how the physique ovulates: “Sperm can dwell as much as 5 days protected by cervical mucus. Otherwise, the vagina is very acidic and sperm will die inside hours.” With that in thoughts, “semen displacement would subsequently solely be a difficulty if a feminine is having intercourse with a number of males inside a interval of hours or throughout ovulation,” she says.

Personally, I’d prefer to suppose penises are mushroom formed in a years-long effort to create pleasurable sensations for each males and girls throughout intercourse. Daniel Boyer, MD, agrees: “The form is primarily a bodily adaptation to extend effectivity and facilitate profitable mating.” The mushroom aesthetic additionally offers the penis a extra interesting look. It makes it much less “Hey, take a look at this lengthy factor” and extra “Look at this factor that vaguely resembles a meals that would have you ever tripping very quickly.”

So no matter what technique or principle you consider, you now have all the data it’s essential drunkenly carry it up at joyful hour with your folks. Enjoy.
