title: Olfaction: attracting both sperm and the nose.
abstract: Odorant receptor genes are expressed not only in the nose but also in testes, where they have been hypothesized to play a role in sperm chemotaxis. New data demonstrate that human odorant receptor hOR 17-4 may play similar roles in both tissues, lending support to the idea that chemical attraction is important for reproduction.
