Giving Birth Through a Penis

Consider the sex life of the spotted hyena, depicted in three shocking photographs at New York's Museum of Sex (MoSex).

``When the male inserts himself into the female, it looks like a mid-air refueling,'' Joan Roughgarden, a professor of evolutionary biology at Stanford University, said in an interview.
