02/01/2016 PSY 234— Human Sexual Behavior Prof. Pointek FIRST EXAM— FEBRUARY 29 • Correct term for female reproductive organ: Vulva— vagina is only the vaginal canal • After sexual activity for females— urinate to prevent urinary tract infection. The acidity of urine will kill bacteria (drinking cranberry juice increases acidity) • Uterus: muscle, Bladder: muscle, more similar to a balloon (and loses elasticity over time) • Ovulation: the release of eggs from the ovary • Egg is fertilized in the fallopian tube, and then moves to the uterus • Eggs are alive and viable for 24 hours out of 30 days, and the sperm remains active for 3 days • Ovarian Cycle • Follicular phase— maturation of follicle (10 days) • Ovarian phase— day 14, OVULATION (24 hours) • Luteal phase— lasts for 14 days, where the lining of the uterus is in waiting (for fertilization or not) • Menstrual Cycle: • Menstrual phase— shedding of the endometrium lining (5 days) • Proliferative phase— endometrium lining building up (10 days) • Secretory phase— waiting for 14 days (similar to luteal) (14 days) • two MAIN female hormones: estrogen, and progesterone • estrogen is made in the ovaries, used to mature the follicle (follicular phase), and formation of the lining • progesterone: maintains the lining, and keeps it in place (when pregnant, progesterone stabilizes) • Path of the sperm: • Testis— sex gland, where sperm is grown and developed + testosterone • Epididymus— where sperm is held • Vas Deferens— tubes that carry the semen from the epididymus to the penis (urethra) What makes up the spem: • Seminal Vesicle— forms 60% of sperm ﬂuid, which is sugar solution (energy) • Prostate— 30-35% alkalide solution • Cowpers— 30-35% alkalide solution: this helps protect the sperm from the vaginal acidity, and create its own environment • SEMEN IS ONLY 5% OF SOLUTION • Urethra— where either perm or urine go through to exit (either or, both cannot go through at the same time) • 200 million sperm released at ejaculation, only 50 ﬁnd the egg— and only 1 fertilizes the egg
