Hormones are substances that transfer signals between the body's cells and organs and regulate bodily functions. In the 1930s Adolf Butenandt contributed to the mapping of several hormones that specifically apply to men and women, respectively. After determining the composition of the female sex hormone estrogen, he was able to determine the structure for this hormone and a related hormone, estriol. He was also able to produce a male sex hormone in pure form for the first time and to determine its chemical composition. It was named androsterone.
