It lived around 75 million years ago, during the Cretaceous period, and was around 8 metres long. Both birds and crocodiles have âcloacasâ , so itâs likely that dinosaurs did too. Cloacas are one opening that deals with intestinal, reproductive, and urinary tracts.In most early bird species, males had a penis that only emerged from the cloaca to deliver sperm when they had sex.

Alopecia areata â an autoimmune disease that affects up to 2% of the population. It causes round patches of hair loss and can lead to total baldness. In many cases, the hair regrows. There are about 50 different hair loss disorders among men and women.
The hormonal process of testosterone converting to DHT, which then harms hair follicles, happens in both men and women. Under normal conditions, women have a minute fraction of the level of testosterone that men have, but even a lower level can cause DHT- triggered hair loss in women. Certainly when those testosterone levels rise, DHT is even more of a problem. DHT levels can be elevated and be within what doctors consider ânormal range.
