Gonopodial morphogenesis in female mosquitofish gambusia affinis affinis masculinized by exposure to degradation products from plant sterols


, : Gonopodial morphogenesis in female mosquitofish gambusia affinis affinis masculinized by exposure to degradation products from plant sterols. Environmental Biology of Fishes 24(1): 43-52

Female mosquitofish, Gambusia affinis affinis, were masculinized by exposure to degradation products (presumably steroids) of the plant sterol, stigmastanol. Masculinization was indicated by the induction of a male-like gonopodium in each specimen. The morphogenetic stages of gonopodial development are discussed as are the anatomical specialization produced in the mature gonopodial tip.
