Serono was a biotechnology company headquartered in Geneva, Switzerland. It was acquired by the German pharmaceutical company Merck in 2006. The company was founded as the Serono Pharmacological Institute by Cesare Serono in 1906 in Rome, Italy. A key step in its development was the discovery of a method of extracting urinary gonadotropins by Dr. Piero Donini. Serono was incorporated in 1987 and the holding company, Ares-Serono S.A., changed its name to Serono S.A. in May 2000.
