Definition of Macroorchidism

Macroorchidism: Abnormally large testes. To determine if the testes are too large, a device called an orchidometer is used that permits a testis to be compared to a series of plastic ovals (like miniature American footballs) of differing sizes. Macroorchidism is a diagnostic feature, for example, of the fragile X syndrome, the most common inherited form of mental retardation. The opposite of macroorchidism is microorchidism.
