|
Penis
|
male sex organ (internal root, external shaft and glans)
|
|
|
Ovary
|
female gonads that produce ova and sex hormones. Egg releases a scent to attract the sperm (guiding it)
|

Clitoris
|
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.

|
Vagina
|
A stretchable canal in the female that opens at the vulva and extends about 4 inches into the pelvis.
|
|
|
Uterus
|
A pear shaped organ inside the female pelvis. The fetus develops in the uterus.
|
|
|
Perineum
|

anus
|
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.
