Effect of the LH:FSH Ratio in the Late Luteal Phase on Follicular Growth of the Next Menstrual Cycle
It is well known that gonadotropins play important roles in the development of ovarian follicles. Recently, the accuracy for measuring various hormones has been improved by using the specific purified monoclonal antibodies (MCA) (1, 2). It has also been pointed out that the growth of the main follicle begins during the late luteal phase of the last menstrual cycle (3, 4). The present study was performed to elucidate whether the serum gonadotropin levels in the late luteal phase affected follicular growth in the following menstrual cycle.
