Overview

Hypogonadism is a medical term for a defect of the reproductive system which results in lack of function of the gonads (ovaries or testes).

Historical Perspective

Hypogonadim was first reported by Dr. Maestre de San Juan in a case of small testes and loss of smelling sense in patient. Dr. Kallmann after that, in 1944, identified this syndrome and it was named based on his name. Dr. de Morsier reported various cases of hypogonadism with abscent olfactory bulbs in the 1950s.

Classification

Hypogonadism may be classified according to the etiological site into three subtypes primary, secondary or combined. It can also be classified according to the age into two adult and child. Based on the causes, it can be classified into acquired or congenital.[1]
