seminiferous tubules
sperm formation begins here; in testis
epididymis
sperm maturation and storage
vas deferens
rapid transport of sperm
bulbourethral gland
produce lubricating mucus
LS, FSH
secretions of anterior lobe of pituitary gland; controlled by hypothalamus; cause Leydig cells to secrete testosterone
spermatagonia -> 1, 2 spermatocyte -> early spermatid -> late spermatid -> immature sperm
PSA test
of prostate specific antigens
ovaries
oocyte production and maturation, sex hormones
uterus
chamber where new individual develops
cervix
mucus secretion that enhanvces sperm mvt into uterus
follicular
stage 1 menstrual; endometrium breaks down and rebuilds; oocyte maturation
ovulation
stage 2 menstrua; release of oocyte from ovary
luteal
stage 3 menstrual; corpus luteum forms; endometrium thickens
GnRH
hypothalamus (hormone)
oral contraceptives
- contain synthetic estrogen, progesterone
- hypothalamus fails to signal start of development of an ovarian follicle
- ovulation ceases
vasectomy
vas deferns cut to prevent sperm from reaching urethra
prostate enlargement
as men grow older; gland presses on urethra, causing urination and bladder problems
HPV
virus easily spread by skin-to-skin contact during sex; causes cancer
high FSH levels
more likely twins
ruptures to release oocyte
uterus lining
release an oocyte
ovaries
FSH levels
high until ovulation, then drops
estrogen, progesterone levels
low until ovulation, then shoots up
tubal ligation
remove short section from each oviduct (tie or ligate other ends)
