Bilbourethral glands

Pair of exocrine glands near the male urethra. They secrete fluid into the urethra (Cowper glands)

Ejaculation

Ejection of sperm and fluid from the male urethra.

Ejaculatory duct

Tube through which semen enters the male urethra

Epididymis

one of a pair of long, tightly coiled tubes above each testis. It stores and carries sperm from seminiferous tubules to the vas deferens.(Plural: epididymides)

Erectile dysfunction

Inability of an adult male to achieve an erection; impotence

Fraternal twins

Two infants resulting from fertilization of two separate ova by two separate sperm cells.

Glans penis

Sensitive tip of the penis; comparable to the clitoris in the female.

Identical twins

Two infants resulting from division of one fertilized egg into two distinct embryos. Conjoined twins are incompletely separated identical twins.

Interstitial cells of the testes

Specialized cells that lie adjacent to the seminiferous tubules in the testes. These cells produce testosterone (also called Leydig cells).

Parenchyma tissue

Essential distinctive cells of an organ. In the testis, the seminiferous tubules that produce sperm are parenchymal.

Penis

Male external organ of reproduction

Perineum

External region between the anus and the scrotum in the male

Prepuce

Foreskin; fold of skin covering the tip of the penis

Prostate gland

Exocrine gland at the base of the male urinary bladder. The prostate secretes fluid that contributes to semen during ejaculation

Scrotum

External sac that contains the testes.

Prostrate

Lying down

Semen

Spermatozoa (sperm cells) and seminal fluid (prostatic and seminal vesicles secretions), discharge from the urethra during ejaculation.

Seminal vesticles

Paired sac-like exocrine glands that secrete fluid (a major component of semen) into the vas deferens.

Seminiferous tubules

Narrow, coiled tubules that produce sperm in the testes.

Spermatozoon

Sperm cell.


Plural: spermatozoa

Sterilization

Procedure that removes a person's ability to produce or release reproductive cells; removal of testicles, vasectomy, and oophorectomy are sterilization procedures.

Stromal tissue

Supportive, connective tissue of an organ, a disinguished from its parenchyma (also called stroma)

Testis

Male gonad (testicle) that produces spermatozoa and the hormone testosterone. Plural: testes

Testosterone

Hormone secreted by the interstitial tissue of the testes; responsible for male sex characteristics.

Vas deferens

Narrow tube (one on each side) carrying sperm from the epididymis toward the urethra (aka ducts deferens)
