Reproductive System
By: Coraima Lagunas
Anatomy of male and female reproductive structures & their functions
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)
disorders
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
Events of the female hormonal cycle
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)
hormones
• 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
major functions
to develop offspring
produce eggs and sperm
produce hormones
