Reduction in penis size and plasma testosterone concentrations in juvenile alligators living in a contaminated environment.

General and comparative endocrinology - 1 Jan 1996

Abstract excerpt

The development of the male reproductive ducts and external genitalia in vertebrates is dependent on elevated androgen concentrations during embryonic development and the period of postnatal growth. We have observed that a population of juvenile alligators living on Lake Apopka exhibit significantly smaller penis size (24% average decrease) and lower plasma concentrations of testosterone (70% lower...
