female sex hormones. The primary and most well-known androgen is testosterone.

Apocrine Glands: Apocrine sweat glands develop during the early to mid puberty ages
approximately around the age of 15 and release more than normal amounts of sweat for approximately
a month and subsequently regulate and release normal amounts of sweat after a certain period of time.
They are located wherever there is body hair. These glands produce sweat that contains fatty materials.
Mainly present in the armpits and around the genital area, their activity is the main cause of sweat odor,
due to the bacteria that break down the organic compounds in the sweat.

Bulbourethral Glands: male accessory sex glands that secrete mucus for lubrication

Chemotaxis: Chemotaxis is a kind of taxis, in which bodily cells, bacteria, and other single-cell or
multicellular organisms direct their movements according to certain chemicals in their environment.
This is important for bacteria to find food (for example, glucose) by swimming towards the highest
concentration of food molecules, or to flee from poisons (for example, phenol). In multicellular
organisms, chemotaxis is critical to development as well as normal function. In addition, it has been
recognized that mechanisms that allow chemotaxis in animals can be subverted during cancer
metastasis.

Corpora Cavernosa: one of a pair of a sponge-like regions of erectile tissue which contain most
of the blood in the male penis during erection

Ductus Deferens: epididymal ducts from each testis converge to form a large, thick walled,
muscular duct

Ejaculatory Ducts: two ducts, receive sperm from the ductus deferensand secretions from the
seminal vesicle; the ducts then empty into the urethra

Epididymis: comma shaped and loosely attached to the rear surface of each testis

Erectile Tissue: smooth muscle and connective tissue inside the penis that contain blood sinuses;
large, irregular vascular channels

Erection: the penis at it’s enlarged and firm state; occurs when the corpora cavernosa become
engorged with venous blood

Flagellum: the whip-like tail of a sperm, propels the sperm towards the egg in hopes of achieving
fertilization

Follicle-Stimulating Hormone (FSH): hormone that stimulates production of sertoli cells, to
make immature sperm to mature sperm

Glans Penis: distal end of the penis, covered with the foreskin

Gonadotropin-Releasing Hormone (GnRH): hormone secreted by the hypothalamus into the
pituitary gland; two types, FSH and LH

Libido: In its common usage, it means sexual desire; however, more technical definitions, such as
those found in the work of Carl Jung, are more general, referring to libido as the free creative—or
