Conventional classification of reproductive modes in female elasmobranchs fails to account for the diversity in ovarian dynamics that operate during oviparous and viviparous cycles. Delineating this diversity is crucial for understanding the endocrin

Relaxin is a 6-kd polypeptide that exerts important hormonal effects in many female mammals. Relaxin is produced by the ovary, placenta, or uterus in many mammalian species. The functions of relaxin in the male mammal are not yet firmly established,

In order to determine the regulation of the oviduct progesterone receptor inChrysemys picta, radioligand binding studies were performed to determine changes in the high and lower affinity binding sites during the seasonal cycle. Lower affinity sites

The stimulation of yolk protein synthesis by estrogen is a characteristic of female non-mammalian vertebrates; in mammals, however, vitellogenesis has been suppressed as a corollary of the evolution of viviparity. It is our hypothesis that progestero

SUMMARY The synthesis of steroids from [7α-3H]cholesterol, [7α-3H]pregnenolone and [7α-3H]progesterone by lizard and turtle ovarian tissues in vitro was studied. Progesterone, 17α-hydroxyprogesterone, dehydroepiandrosterone, androstenedione, test

These experiments demonstrate that both porcine relaxin and bovine insulin can increase the cervical cross-sectional area in Squalus acanthias. When given after estradiol priming, the magnitude of this response is greater. This effect is limited to S

Amounts of estradiol, testosterone, and progesterone in plasma were measured during the reproductive cycle of female Raja erinacea. Estradiol titers correlated directly with follicle size in females undergoing ovarian recrudescence, while highest con
