[1] His discoveries were important for the field of reproductive endocrinology, the development of hormonal contraceptives, and treatments for infertility.
Ernst Knobil was born in Berlin and lived in Paris before emigrating with his family to the United States in 1940.
In 1989, Knobil became the Ashbel Smith Professor at the University of Texas-Houston Health Science Center.
[5] Knobil is also credited with discovering the key role of pulsatile gonadotropin-releasing hormone and estrogen feedback during the menstrual cycle.
This work today forms the basis of reproductive endocrinology[6] and enabled development of the world's first hormonal contraceptives.
