GENERAL HISTOLOGY

Detailed explanation-1: -In women, ovulation of mature follicles on the ovary is induced by a large burst of LH secretion-the preovulatory LH surge. Residual cells within ovulated follicles proliferate to form corpora lutea, which secrete the steroid hormones-progesterone and estradiol.

Detailed explanation-2: -The hypothalamus secretes GnRH in a pulsatile fashion, which triggers FSH and LH release from the anterior pituitary. These, in turn, act on the granulosa and theca cells in the ovary to stimulate follicle maturation and trigger ovulation.

Detailed explanation-3: -Ordinarily, it’s secreted at very low levels throughout your menstrual cycle. But once a developing egg follicle reaches a certain size-usually around the midpoint of your cycle-LH secretion surges to really high levels. This hormone surge is what triggers ovulation about 24 to 36 hours later.
