In the spontaneous menstrual cycle, the mid-cycle gonadotrophin surge causes maturation of the cumulus-oocyte complex, mucification of cumulus cells and expansion of the cumulus oophorus, resumption of meiosis and maturation of the cytoplasm of the oocyte. Whether this is an effect purely of luteinizing hormone (LH) or whether follicle stimulating hormone (FSH) also plays a role is unknown. The effect of an artificially induced FSH surge at the time of human chorionic gonadotrophin (HCG… CONTINUE READING
