The American Society of Andrology (ASA) is now 40 years old. The ASA Archives and History Committee helped the Society celebrate the 40th year anniversary and honored the founding members at the 40th Annual Meeting in Utah. This book, ÒAmerican Society of Andrology Celebrating 40 Years: 40 and ForwardÓ, traces the origin of the ASA and displays its unique diversity, including a strong recognition of Women in Andrology. It is our hope that this collection of history and photos from past meetings reminds us of the tremendous potential the future holds, as the ASA continues to advance forward.
