hormone exposure, perhaps not as dramatically as animals because most humans are born as singletons," Vandenbergh said. Human studies of fraternal twins have shown that girls with a twin brother, who were therefore exposed to testosterone in utero, s...
Cutting the risk of coronary disease - start before birth says UK doctor

diagnosis. But Fink indicates that a test for a mutated SPG3A gene sequence will soon allow HSP specialists and geneticists to provide genetic counseling. Such testing and counseling might be valuable to couples whose family or medical history sugges...
Major stress during pregnancy linked to autism
