Study Notes
Hormones and Functions
- Ovaries produce hormones such as estrogen, progesterone, and inhibin; androgens are produced but not in significant amounts.
- Broad ligament functions to support and stabilize the uterus, ovaries, and fallopian tubes within the pelvic cavity.
Granulosa Cells
- Granulosa cells synthesize inhibin and activin stimulated by follicle-stimulating hormone (FSH) and luteinizing hormone (LH).
- Inhibin regulates FSH secretion, while activin enhances FSH action and promotes follicle development.
Androgens in Females
- Androgens are produced in small amounts by the adrenal glands and ovaries, converted to estrogens in peripheral tissues through aromatization.
Ovarian Functions
- Ovaries are responsible for hormone production, oocyte development, and menstrual cycle regulation but do not secrete testosterone.
Supporting Ligaments
- Supporting structures in the female reproductive system include the broad ligament, round ligament, and uterosacral ligament, which provide physical support.
Hormonal Pulses
- Gonadotropin-releasing hormone (GnRH) is released in pulses from hypothalamic neurons, stimulating the anterior pituitary to secrete FSH and LH.
Theca Cells
- Main function of theca cells is to produce androgens, which are essential for estrogen synthesis in the ovaries.
