It was the most complex penis transplant ever performed.
Oh, how modern technology spoils us.
A man recovering from penile cancer is the first American citizen to receive a penis transplant. The operation, a first in the United States, was performed by doctors at the at Massachusetts General Hospital in Boston. According to the doctors involved, more transplants will occur in the coming years. This is still, however, an experimental procedure at the forefront of medicine.
Ahh, the phallus. In most sexually-reproductive species, half of the individuals lack one, while the other half is constantly trying to share theirs as much as possible with the first group, with varying degrees of success — bragging, fighting or impressing their way to the continuation of the species. Marvelous!
A breakthrough study authored by Harvard University developmental biologists has finally resolved the mystery of how sexual organs appeared for the first time in vertebrates. According to their findings, shortly after our sea-dwelling ancestors migrated on land, creatures were pressured to quickly evolve genitalia – which they didn’t require up until then. These sexual organs, at least for snakes and lizards, originated
A female insect has developed a spiky penis which it uses to get in charge . It’s a role reversal, basically: not only do the females have a penis, but the males have a vagina. The males still have sperm, but the female extracts it from the male vagina using its penis. Sounds strange, doesn’t it? Researchers thought so too. What
The case of birds missing out on a proper penis has been a longstanding mystery in evolutionary biology. Roughly 97% of avian species sport little or nothing like a real phallus, yet they still reproduce via internal fertilization. A new study, conducted by Martin Cohn, a developmental biologist at the University of Florida in Gainesville and published in Current Biology
It’s been long theoretized by most women, and not only, that there is a connection between the penis and the brain – and research done by Gill Bejerano, a biologist at Stanford University School of Medicine, and colleagues seems to support that theory, at least in a way. Let’s look at our close relatives, the chimpanzees. Humans and chimps share
