* induced ovulation: sexual receptivity occurs in spontaneouscycles, but ovulation does not occur without copulation (cats,rabbits, ferrets)

Psychology experiments about preferences for faces and voices
Professor Simon Baron Cohen, a psychologist and Director of the Autism Research Center at Cambridge University, has a special interest in male/female brain types, particularly in relation to autism, and wanted to find out whether levels of testosterone in the womb affected behavior. Luckily, the University hospital is a regional center for amniocentesis (a procedure in which fluid is taken from the amniotic sac for analysis) and once the necessary tests had been done, it was their policy to freeze the remainder of the sample. Baron Cohen and his team contacted women whose samples were still in the deep freeze, who now had toddlers and were happy to bring them in for an assessment of their behavior. The researchers found that the higher the levels of prenatal testosterone in the amniotic fluid, the less eye contact the toddlers made, and the smaller their vocabulary. These toddlers were seen again when they were four years old. By this time, those children that had had the highest level of prenatal testoerone had lower social skills and more restricted interests than those who had had lower levels of testosterone in their bath of amniotic fluid.
