The gradual increase in estrogen secretion during the follicular phase is the result of

A) declining FSH levels.
B) granulosa cells converting androgens to estrogen.
C) positive feedback on the anterior pituitary.
D) an LH surge.
E) luteal development.

Estrogen Secretion

Estrogen Secretion refers to the production and release of estrogen hormones by the ovaries, which are vital in regulating the reproductive system and secondary sexual characteristics in females.

Follicular Phase

The phase of the menstrual cycle during which follicles in the ovary mature, ending with ovulation.

Granulosa Cells

Specialized cells within the ovary that surround developing eggs (oocytes) and secrete hormones necessary for oocyte maturation and regulation of the menstrual cycle.
