Male Reproductive System
Lecture 8
Anatomy
• Testis or testicle = main male sex organs,
paired, oval shaped, enclosed in a sac called
the scrotum.
– Seminiferous tubules = coiled tubes within the
testes where sperm have their beginning.
– Epididymis = a pair of coiled tubes atop the
testes that carry the mature sperm up to the vas
deferens.
• Vas deferens = duct that carries sperm to the
urethra.
Anatomy
• Seminal vesicles = main glands at the base of the
bladder, open into the vas deferens. Secrete a
thick fluid which forms part of the semen.
• Prostate gland= encircles the upper urethra,
secretes a fluid that aids in the movement of sperm
and ejaculation.
• Scrotum = sac suspended on both sides and just
behind the penis.
• Penis = male organ of urination or copulation.
• Semen = composed of sperm, seminal fluid & other
fluid

Vas/o = vessel, duct.
Vesicul/o = seminal vesicles.
Andr/o = male.
Sperm/o spermat/o = spermatozoa, sperm.
Prefix & Suffix

Medical Terms
• Balanitis = inflammation of the glans penis.
• Balanorrhea = excessive discharge from the
glans penis.
• Benign Prostatic Hypertrophy [BPH] =
nonmalignant excessive development of the
prostate gland.
• Epididymitis = inflammation of an epididymis.
• Prostatitis = inflammation of the prostate gland.
• Prostatolith = stone in the prostate gland.
Medical Terms
• Prostatovesiculitis = inflammation of the prostate
gland and seminal vesicles.
• Erectile dysfunction = inability to attain or maintain
an erection sufficient for sexual intercourse.
• Hydrocele = scrotal swelling.
• Phimosis = narrowing of constriction of the
opening of the prepuce (foreskin) of the glans
penis.
• Prostatic cancer = cancer of the prostate gland.
Medical Terms
• Varicocele = enlarged veins of the spermatic cord.
• Testicular torsion = twisting of the spermatic cord
causing decreased blood flow to the testis.
• Orchioplasty = surgical repair of a testis.
• Orchiectomy = excision or surgical removal of one
or both testes. (castration).
• Prostatectomy = excision of the prostate gland.
• Vasectomy = excision of a duct, sterilization.
• Circumcision = removal of the prepuce.

Aspermia = absence of sperm.
Oligospermia = scanty sperm (in semen).
Spermatolysis = dissolution of sperm.
AIDS = acquired immune deficiency.
Artificial insemination = introduction of semen into
the vagina by artificial means.
• Chlamydia = STD, painful urination & discharge,
male and female can acquire.
• Coitus = sexual intercourse male & female
Complementary Terms
• Gonads = male & female sex glands.
• Gonorrhea = STD, bacterial organism affects
the mucous membranes.
• Heterosexual = attracted to the opposite sex.
• Homosexual = attracted to the same sex.
• Human papilloma virus = prevalent STD,
benign cancerous growths in the male &
female genitals (venereal warts).
• Prosthesis = artificial replacement of an absent
body part.
Complementary Terms
• Puberty = period when secondary sex
characteristics develop.
• STD= sexually transmitted disease.
• Sterilization = renders an individual unable
• to produce offspring.
