Ovine LH and ovine FSH stimulated progesterone production in granulosa cells isolated from the F1, F2 and F3 follicles of hypophysectomized and control (sham-operation) hens when they were collected 6 h after operation, but the steroidogenic response to LH was greater for granulosa cells from hypophysectomized hens. At 15 h after operation progesterone production by granulosa cells was stimulated by LH in all 3 follicle types of control hens, but only in the F1 follicles of hypophysectomized hens. The response to FSH at 15 h was similar for control and hypophysectomized hens. The time after hypophysectomy therefore appears to affect the LH-stimulated progesterone production by granulosa cells of the F2 and F3 follicles.
