The Male Reproductive System

psychic—energy an individual has to put toward personal development, or individuation.

Luteinizing Hormone (LH): hormone that stimulates Leydig cells in the testes to produce
testosterone

Oviduct: the passage in females from the ovaries to the outside of the body.

Penis: external genital organ of the male

Prostate Gland: male accessory sex gland that secretes an alkaline fluid, which neutralizes acidic
vaginal secretions

Puberty: the period of maturation and arousal of the dormant and nonfunctional reproductive
system; usually occurs in males between the ages of 10 and 15

Scrotum: skin covered sac that houses the male testicals; keeps the testicals away form the body
so that it can stay a few degrees cooler than the body, for better sperm production

Seminal Vesical: male accessory sex glands that supply fructose to ejaculated sperm and secrete
prostaglandins

Seminiferous Tubules: highly coiled tubules within the testes that produce spermatozoa

Sertoli Cell: A Sertoli cell (a kind of sustentacular cell) is a 'nurse' cell of the testes which is part
of a seminiferous tubule.

It is activated by follicle-stimulating hormone, and has FSH-receptor on its membranes.

Its main function is to nurture the developing sperm cells through the stages of spermatogenesis.
Because of this, it has also been called the "mother cell." It provides both secretory and structural
support.

Sexual Homology: sex organs that evolve from the same tissues in both male and females

Sperm: main reproductive cell in males

Spermatogenesis: sperm production

Testes: located in the scrotum, produces testosterone which stimulates production of sperm

Testosterone: male sex hormone secreted by the leydig cells of the testes, vital for the production
of sperm

TURP: transurethral resection of the prostate. During TURP, an instrument is inserted up the
urethra to remove the section of the prostate that is blocking urine flow. This is most commonly caused
by benign prostatic hyperplasia (BPH). A TURP usually requires hospitalization and is done using a
general or spinal anesthetic. It is now the most common surgery used to remove part of an enlarged
prostate.
