Homo ou hétéro, est-ce un choix ?

Is homosexuality against nature? What is the part of the innate and the acquired? To these "existential" questions, science and its latest experiments offer a new light. From conjectures to investigations, testimonies, in vivo and in utero experiments... men and women scientists express themselves, all sexual tendencies and nationalities included.
