WebJan 5, 2024 · At the start of each estrous (animal) or menstrual cycle (human), in response to a surge of luteinizing hormone (LH) from the pituitary gland, a limited number of primordial follicles are triggered to develop into primary follicles, preantral follicles, antral follicles and reach to preovulatory follicle stage. Webconnexin, Cx37, is present from the primary follicle stage onward, restricted to the interface between oocytes and cumulus granulosa cells (Simon et al., 1997), although it should be noted that Wright et al.
