Question

About which day in a normal human menstrual cycle does rapid secretion of LH (popularly called LH-surge) normally occur?

Accepted Answer

According to the text, both LH and FSH attain a peak level in the middle of the cycle (about the 14th day). The rapid secretion of LH leading to its maximum level during the mid-cycle is called the LH surge, which induces the rupture of the Graafian follicle and ovulation .
