GENERAL HISTOLOGY

Detailed explanation-1: -Your ovaries secrete estrogen and progesterone. These hormones play an important role in reproductive development and menstruation. Estrogen production is highest in the first half of your menstrual cycle before ovulation.

Detailed explanation-2: -GnRH stimulates the pituitary gland to produce follicle stimulating hormone (FSH), the hormone responsible for starting follicle (egg) development and causing the level of estrogen, the primary female hormone, to rise.

Detailed explanation-3: -Estrogen and oestrogen are both English terms. Estrogen is predominantly used in American (US) English ( en-US ) while oestrogen is predominantly used in British English (used in UK/AU/NZ) ( en-GB ).

Detailed explanation-4: -Along with progesterone, estrogen plays a key role in your reproductive health. The development of secondary sex characteristics (breasts, hips, etc.), menstruation, pregnancy and menopause are all possible, in part, because of estrogen. Estrogen plays an important role in other body systems, too.
