procedureThe menstrual cycle proceeds in five steps: (1) The pituitary gland produces FSH, which signals the ovaries to produce estrogen. (2) When estrogen reaches a specific level for a set duration, the pituitary gland produces LH. (3) LH triggers ovulation, causing the ovary to release an egg into the fallopian tube.
