Maybe you grew so fast it left stretch marks on your legs. Or your voice started cracking every time you got on the phone. Or you hated needing to wear a bra. Growing up means going through puberty.

You may have noticed some news around these weird sounding devices that measure “arousal”. They don’t. But they do measure changes in penile shape, and as such, can give users a rough estimate – in a non-invasive way – of how much blood is flowing into the penis during erection. »
An international team of scientists have isolated a gene within the Aedes aegypti mosquito that partially transforms females into males. Since only females spread diseases by feasting on human blood, the discovery could lead to powerful population control strategies.
Good morning, and get ready to get a bad case of internal shivers! This morning’s body horror is provided by toxic epidermal necrolysis, which can be induced by... so many things. So many things. »
The quick and dirty route to gaining strength is to take some kind of anabolic steroid. These drugs actually trick the body into building up muscle mass and endurance — but they can also age you far beyond your years. »

There was once a time when the cutting edge in pain relieving technology was a stick to bite down on. It was only when sticks ran short that people turned to pills. How do these work?
Crab lice (Pthirus pubis) aren’t crabs at all—they’re parasitic insects that feed exclusively on human blood, and their bites can cause intense itching in their hosts. Often, this itching happens in the pubic area, which is why they’re also known as “pubic lice”—which, it turns out, is actually a misnomer. »
Nearly 100 years ago, there was no drug to help with erectile dysfunction, but Bernard Scheinkman came up with an alternative. It’s not clear whether this nightmarish penile splint was ever manufactured — but you have to love the baroque logic of combining a cock ring, an open condom, and a shelf. »
A study published last week in the journal Biofabrication describes a new technique to build replacements for damaged three dimensional human tissues. The researchers running the study are trying to make an eardrum. But their technique, if successful, might also one day create replacements for complex reproductive… »
We know how to successfully freeze, store, and thaw human sperm. We’re still on a learning curve with human eggs. Abby Rabinowitz’s recent feature at Nautilus explores the all-too limited statistics about how well the process works and the data on why more healthy women are choosing to try it anyway. »
Viagra. Levitra. Cialis. Stendra. For millions of men with erectile dysfunction, these drugs are the action heroes of the bedroom, breaking down the barriers that keep them from a normal sex life. Here’s how they work. »

People in China discovered the cure for leprosy in the 1300s, and yet for six hundred years, the cure didn’t actually work. We’ll tell you why a known cure wasn’t good enough, and how to make it good enough. »
Sex is awesome, but getting a urinary tract infection (UTI) from sex is not. And thanks to the really short passage between their bladders and the bacteria-rich outside world, one in five women will have a UTI sometime during their lives.
Most patients receiving end-of-life care want to avoid aggressive attempts to prolong their life, but medical culture and practices often contradict these wishes.
