Book ChapterDOI
Regulation of Male Gonaducts and Sex Accessory Structures
TL;DR: This chapter shall review briefly the development of the male genital tract (including the gonaducts and associated glands as well as derivatives of the urogenital sinus), secondary sexual characters and the hormonal factors influencing development, structure and function.
Journal ArticleDOI
Androgen receptors in two androgen-mediated, sexually dimorphic characters of frogs.
TL;DR: The presence of androgen receptors in both male and female tissues is consistent with results from hormone experiments in which androgen supplements induce the expression of a nuptial pad and enlarge the external oblique muscles in castrated males and ovariectomized females.
Journal ArticleDOI
Histology and histochemistry of androgen-stimulated nuptial pads in the leopard frog, Rana pipiens, with notes on nuptial gland evolution
TL;DR: Nuptial pads are digital specializations of male frogs that cycle with the reproductive season and are considered to function in mating and gland secretions were analyzed histochemically in androgen-stimulated overwintering leopard frogs to provide information on gland function and physiological control.
Journal ArticleDOI
Induction of cloacal and dermal skin glands of tiger salamander larvae, (Ambystoma tigrinum): effects of testosterone and prolactin.
TL;DR: Treatment of male and female tiger salamander larvae with testosterone induced precocious formation of ventral cloacal glands and stimulated proliferation and differentiation of mucous and granular glands in the ventral dermis of the skin.
Journal ArticleDOI
Sexual dimorphism and testosterone responsiveness in hypaxial muscles of the northern leopard frog, Rana pipiens
TL;DR: In overwintering males, exogenous testosterone cypionate stimulated a significant increase in mass and protein content of the abdominal oblique and rectus abdominis muscles.
