Scientists have discovered four species of Brazilian insects in which the females possess a penis and the males possess a vagina. This announcement, made today in the journal Current Biology, represents the first documented instance of a “female penis” in the animal kingdom.
Contrary to popular belief, the presence or absence of certain sex organs isn’t the determining factor when deciding which animal of a species is female and which is male. In fact, biologists don’t use sex chromosomes either. They actually rely on the size of an animal’s gametes — sperm in males and oocytes in females. As the rule goes, females are the sex that contribute the largest gametes, whereas males are the sex that contribute the smallest gametes and therefore expend the least amount of energy on producing these cells. So, in this particular instance of sex-role reversal, the convention still applies: the female in these species of insect produces the largest gametes — egg cells. She simply also happens to sport a penis that she introduces into the male’s vagina during copulation.
When it’s time to mate, the female mounts the male and penetrates his vagina-like opening using her gynosome — the term used to designate her female-penis. This mating behavior lasts for an impressive 40 to 70 hours, thanks to the female’s inflatable, spiny penis that anchors itself to the male’s internal tissues. During this time, the female Neotrogla gathers large quantities of sperm that she uses to fertilize her eggs. “Because the female’s anchoring force is very strong, a male’s resistance may cause damage to his genitalia,” Yoshizawa said. “Therefore, it is very likely that entire mating processes are controlled actively by females, whereas males are rather passive.”
Michael Siva-Jothy, an entomologist at the University of Sheffield, UK, who didn’t participate in this study, said in an email to The Verge that the findings are “really, really exciting.” Examples like this, he noted, allow researchers to examine various factors that drive how these traits evolve. When asked how the female penis might have evolved, however, Siva-Jothy was stumped. “This is so bizarre,” he said. “I don’t know where to begin.”

Actually you’re not considered dead when your heart stops beating. This is why many medical professionals still try to revive those whose hearts have stopped. Because medicine and science has found that death is not considered when your heart as stopped, but once all brain activity has ceased. Which is why they usually have around six minutes before there is no chance to revive. Because when the heart has stopped, your brain cells are deprived of oxygen and start to die.
Fetuses do not have regular brain activity until 25 weeks. At this point in gestation the only time an abortion would be performed is out of medical necessity to save the mother’s life, or to spare the fetus from a short and painful life. These only make up 1% of all abortions. And therefore by this argument, but with the knowledge of what is actually classified as death, a fetus isn’t ‘alive’ until roughly 25 weeks. Far after 99% of abortions are performed.
Please do actual research before trying to use emotional manipulative photos of babies that are born and NOT fetusesbefore parading it out and believing it as fact. Because you are only seriously misinforming yourself, and many others and furthering contributing to a movement that tries to control women’s bodies, when what they do with it does not affect you.
If you are so adamant about helping lives, try doing things for those who are in need and are actually sentient beings. Volunteer at a soup kitchen, donate to an organization that helps feed hungry children, support adoption of older children who are in foster care and are more likely to age out. But this? This does nothing.
