GENERAL HISTOLOGY

Detailed explanation-1: -FSH stimulates granulosa cells in the ovarian follicles to synthesize aromatase, which converts androgens produced by the thecal cells to estradiol.

Detailed explanation-2: -As the dominant follicle matures, so does the egg inside that will eventually be released when you ovulate. The dominant follicle releases more estrogen into your body. The increased estrogen thickens your uterus lining so that a fertilized egg (embryo) can implant there.

Detailed explanation-3: -As the follicle grows it produces oestradiol. As oestradiol levels rise this induces the hypothalamus and pituitary gland to make high levels of LH (and some FSH) at the midpoint of the cycle to induce ovulation.

Detailed explanation-4: -The menstrual cycle is regulated by hormones. Luteinizing hormone and follicle-stimulating hormone, which are produced by the pituitary gland, promote ovulation and stimulate the ovaries to produce estrogen and progesterone.
