MICROANATOMY

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: -Circulating estrogen levels increase until they activate the hypothalamic-pituitary axis producing a surge release of luteinizing hormone (LH). This is the estrogen positive feedback that triggers ovulation.

Detailed explanation-3: -Leutinizing hormone (LH), the other reproductive pituitary hormone, aids in egg maturation and provides the hormonal trigger to cause ovulation and the release of eggs from the ovary.

Detailed explanation-4: -After a dominant egg has grown large enough for ovulation and your body has produced a large amount of estrogen, LH production, which is low throughout your cycle, ramps up and up over a period of days until it ‘peaks’ or ‘spikes, ‘ signaling for your body to release the dominant egg in hopes of achieving pregnancy.
