Sex Chromosome XX and XY
Human cells have 22 pairs of matched chromosomes. The sperm has one chromosome (x or y) and the ovum has one (always X). Sex chromosomes influence biological sex determination.
Hormone produced by the ovaries. Influence the development of female cell characteristics (secondary sex characteristics) and helps regulate the menstrual cycle. Estrogen is also produced in small amounts by the adrenal gland in both sexes. Secreatroy phase of menstral cycle (2nd phase). Builds up uterus walls so egg can implant. Resp. for increased maternal beh. as demonstrated in animals w/ ovaries removed. In menopause, estrogen and progesterone drops to 0.
Hormone (steroid) produced by the ovaries and secreted by the corpus luteum and placenta. Regulates the menstrual cycle and stimulates the development of the uterine lining. Prepares the body for pregnancy. Used in birth control pills and hormone replacement therapy. Helps induce menstrual periods, regulate abnormal bleeding, and assist w/ infertility issues and PMS therapy
Androgen (testerone)
Primary hormone produced by the testes and adrenal glands in males, by adrenal glands only in females. Resp. for genitalia & arm pit hair in both sexes. Assoc. w/ increased aggression & sex drive. Test. decreases, but not to 0 as you age, less sex drive, may feel down, less aggressive
Testerone (androgen)
androgen that influences the development of male sex characteristics and sexual motivation.
Reproductive organs (male and female). Undifferentiated until 6 wks, the gonads differentiate into testes (male) & ovaries (female).
male sex organ (internal root, external shaft and glans)
female gonads that produce ova and sex hormones. Egg releases a scent to attract the sperm (guiding it)
a highly sensitive structure of the female external genitals. Same number of nerve endings as head of the penis. Purpose is sexual pleasure. external physical structure comes from same embryological organ as penis.
A stretchable canal in the female that opens at the vulva and extends about 4 inches into the pelvis.
A pear shaped organ inside the female pelvis. The fetus develops in the uterus.
The area between the vagina and anus of the female and the scrotum and the anus of the male
opening at the end of the rectum. Behind the vagina in women and testicles of men. Can be a sexual organ.
Grafenburg spot
glands and ducts located in the anterior wall of the vagina (behind pubic bone). Some women may experience sexual pleasure, arousal, orgasm, and an ejaculation of fluids (G-spot). Not in the uterus or clitoris.
menstrual period
the sloughing off of the built-up uterine lining that takes place if conception has not concerned. Issue in sex therapy. Females most fertile mid-cycle. Day 1 is 1st day of menstrual bleeding. Uterine wall is think under progesterone influence. If egg is not fertilized it will lead to sloughing off=bleeding=no child. Birth control-don't have sex mid cycle. Day 14 is best for sperm and egg. Do it right before menses.
