Male Reproductive System

1. Male Reproductive System Lecture 8

2. 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.

3. 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

4. Combining forms • Balan/o = glans penis. • Epididym/o = epididymis. • Orchid/o = testis, testicle or test/o, orchi/o. • prostat/o = prostate. • Vas/o = vessel, duct. • Vesicul/o = seminal vesicles. • Andr/o = male. • Sperm/o spermat/o = spermatozoa, sperm.

5. Prefix & Suffix • Trans- = through, across, beyond. • -ism = state of

6. 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.

7. 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.

8. 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.

9. Complementary Terms • Andropathy = diseases of the male. • 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

10. 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.

11. Complementary Terms • Puberty = period when secondary sex characteristics develop. • STD= sexually transmitted disease. • Sterilization = renders an individual unable • to produce offspring.

12. Abbreviations • AIDS= acquired immune deficiency syndrome. • BPH= benign Prostatic hypertrophy. • HIV= human immunodeficiency virus. • HPV= human papilloma virus. • PSA = Prostatic specific antigen. • STD= sexually transmitted disease.
