Are men and women more alike in some populations than in others? It's possible. First, boys and girls differentiate from each other to varying degrees during adolescence, and this process of sexual differentiation is genetically influenced. There are even conditions, like Swyer syndrome, where an individual is chromosomally male (46, XY) and yet develops externally... Read More

By separating out solid fecal waste and rapidly... Read More
What is the main source of estrogen in the environment? Birth control pills? An industrial compound with estrogenic properties, like DDT, PCBs, and dioxins? No, it’s women’s urine. The stuff that gets flushed down toilets millions of times a day. There is also testosterone in wastewater but at much lower levels, being less water?soluble (Tabak... Read More
One point is often raised about male homosexuality: it has always been with us. True, but has it ever changed in its nature or prevalence? Well, more gays have been ‘coming out of the closet.’ People are practicing openly what used to be done in secret. But have there also been more fundamental changes? Such... Read More
