RESUMO
The effects of water extracts of Cynomorium coccineum and Withania somnifera on ovarian follicular development and serum levels of FSH and LH were studied in immature 17-day-old and 25-day-old-Wistar rats. Water extracts of the plants were given to the animals per os in a dose of 47 mg/100 g body weight for 6 days. Serum levels of FSH and LH were measured by ELISA. Folliculogenesis was studied with a light microscope. In 25-day-old rats, extracts of both plants elicited significant changes in gonadotrophin levels coupled with a significant increase in ovarian weight and profound folliculogenesis. Numerous primary, secondary, tertiary and antral follicles were present. A distinct zona pellucida was not seen and the oocyte was often detached. In 17-day-old animals there was a significant increase-in body weight but without significant changes in the ovarian weight and folliculogenesis.
