  • Title: In vitro sensitivity of rat ovarian follicles to the direct action of various hormones applied in particular stages of sexual cycle.
    Author: Gregoraszczuk E.
    Journal: Folia Histochem Cytobiol; 1987; 25(1):17-22. PubMed ID: 3114015.
    Abstract:
    The direct action of various hormones on the ovary of adult rat ovaries has been investigated. The ovaries were surgically exposed at particular stages of sexual cycle i.e. in estrus, metestrus, diestrus and proestrus, and were injected with various doses of gonadotropic hormones. Injected ovaries were excised 56 hrs after injection and examined histologically. The reactivity of the ovaries to hormone applied was dependent on stage of the cycle. The considerable increase of the amount of t1 and t2 follicles was observed after injection of gonadotropins in estrus stage. In metestrus stage the influence of gonadotropins on the follicles more advanced in development was pronounced. Numerous follicles t3 appeared in diestrus under the influence of all used hormones.
