Administration of bovine FSH (10 IU/lizard/alternate day for 30 days) in the postbreeding quiescent phase of the ovarian cycle caused a significant increase in the mean number of oogonia and oocytes, the relative weight of the oviduct, and the liver and serum estradiol levels compared to those of controls. In addition, the FSH-treated Lizards showed a vitellogenic growth of follicles and development through to preovulatory follicles. However, the administration of corticosterone simultaneously with FSH (10 IU FSH + 40 mu g corticosterone/lizard/alternate day for 30 days) did not result in these changes and the ovaries resembled those of controls. The results indicate the absence of ovarian refractoriness to gonadotropic stimulation during the quiescent phase of the reproductive cycle and inhibition of FSH-induced ovarian recrudescence by corticosterone. It is suggested that corticosterone treatment reduces FSH-induced steroidogenic activity of the ovary, leads to impairment in vitellogenin secretion by the liver, and results as well in the failure of vitellogenic follicular growth in Mabuya carinata.
