This is a review of all significant research into the causes of homosexuality, both male and female.

The writers objectively review the scientific studies of gay people and present the findings clearly and in a readable style.
Many interesting questions are asked: What might cause someone to be gay? Does homosexuality run in families? Does childhood behaviour predict adult sexuality?

I recommend this book particularly to gay people. It explains causes of homosexuality and every gay person should have knowledge of this area.

I also recommend this book to anyone who wants to be informed about gay people and sexuality in general. This is an important book that deserves attention and a wide audience.
