Step-by-step solution
During the follicular phase (A), the secretion of gonadotropins (FSH and LH) increases gradually. This stimulates follicular development as well as the secretion of estrogens by the growing follicles (III). During the ovulatory phase (B), the rapid secretion of LH leads to its maximum level during the mid-cycle. This is called the LH surge (I), which induces the rupture of the Graafian follicle and thereby the release of the ovum. During the luteal phase (C), the remaining parts of the ruptured follicle transform i
