Events of the female hormonal cycle

hormones

major functions

to develop offspring

female:
• ovaries- primary sex organ
• ductus system- delivery female gametes (Fallopian tube, uterus, vagina)

male:
• testes- primary sex organ
• sperm- male gamete
• ductus system- delivery of sperm (epididymis, ductus deferns, and urethra)

• leutinizing hormone (LH): stimulates seminiferous tubules to secrete testosterone

• gonadotropin releasing hormone (GnRH): released by hypothalamus to release LH and FSH

• follicle stimulating hormone (FSH): sperm production and maturation, & inhibin

• testosterone – stimulates reproductive organ development and sex drive (male & female)

• inhibin – released by the testes when high levels of testosterone are present to STOP production of LH and FSH

• estrogen – primary female sex hormone released by follicle (in ovary)

• progesterone – triggers suppression of the hypothalamus from releasing GnRH, helps maintain pregnancy

produce eggs and sperm

produce hormones

follicular phase: it starts on the first day of menstruation and ends during ovulation. Each follicle houses an immature egg and matures it for the chance of pregnancy. The follicle-stimulating hormone activates the follicle phase.

luteal phase: the empty follicle develops corpus luteum. Then the corpus luteum develops progesterone, which prepares the uterus for a federalize egg.

ovulation: it releases a mature egg from the ovary (mid-cycle) and it is pushed down to the Fallopian tube to make it available to fertilization.

menstruation: the elimination of the endometrium and has fluids (blood)

Cervical cancer: begins in the cervix

Ovarian cancer: begins in the ovaries

Uterine fibroids: noncancerous tumors in women

Uterine cancer: begins in the uterus

Endometriosis: affecting a woman’s uterus

Vaginal cancer: begins in the vagina

Vulvar cancer: begins in the vulva

prostate cancer: begins in the prostate glads

breast cancer: cancer in the mammary gland
