GENERAL HISTOLOGY

Detailed explanation-1: -The LH surge increases intrafollicular proteolytic enzymes, weakening the wall of the ovary and allowing for the mature follicle to pass through. The surge also causes the luteinization of thecal and granulosa cells forming the Corpus Luteum, which is responsible for progesterone synthesis levels.

Detailed explanation-2: -Luteinising hormone stimulates the corpus luteum to produce progesterone, which is required to support the early stages of pregnancy, if fertilisation occurs.

Detailed explanation-3: -Ovulation marks the end of the follicular phase and the beginning of the luteal phase. During the luteal phase, the dominant follicle that released the mature egg changes into a structure called the corpus luteum. The corpus luteum produces important pregnancy hormones.

Detailed explanation-4: -Luteinizing hormone stimulates egg release (ovulation), which usually occurs 16 to 32 hours after the surge begins. The estrogen level decreases during the surge, and the progesterone level starts to increase. During the luteal phase, luteinizing hormone and follicle-stimulating hormone levels decrease.
