| Question | Answer |
|---|---|
| androgen | Any hormone that produces male characteristics (root andr/o means “male”) |
| bulbourethral gland | A small gland beside the urethra below the prostate that secretes part of the seminal fluid; also called Cowper gland |
| circumcision | Surgical removal of the end of the prepuce (foreskin) |
| coitus | Sexual intercourse |
| ductus deferens | The duct that conveys spermatozoa from the epididymis to the ejaculatory duct; also called vas deferens |
| ejaculation | Ejection of semen from the male urethra |
| ejaculatory duct | The duct formed by union of the ductus deferens and the duct of the seminal vesicle; it carries spermatozoa and seminal fluid into the urethra |
| epididymis | A coiled tube on the surface of the testis that stores sperm until ejaculation (root: epididym/o) |
| erection | The stiffening or hardening of the penis or the clitoris, usually because of sexual excitement |
| follicle-stimulating hormone | A hormone secreted by the anterior pituitary that acts on the gonads; in males, FSH stimulates Sertoli cells and promotes sperm cell development; in females, it stimulates ripening of ova in the ovary |
| gamete | A mature reproductive cell, the spermatozoon in the male and the ovum in the female |
| glans penis | The bulbous end of the penis |
| gonad | A sex gland; testis or ovary |
| inguinal canal | The channel through which the testis descends into the scrotum in the male |
| interstitial cells | Cells located between the seminiferous tubules of the testes that produce hormones, mainly testosterone; also called cells of Leydig (LI-dig) |
| luteinizing hormone | A hormone secreted by the anterior pituitary that acts on the gonads; in males, it stimulates the interstitial cells to produce testosterone; in females, it stimulates ovulation and corpus luteum formation |
| meiosis | The type of cell division that forms the gametes; it results in cells with 23 chromosomes, half the number found in other body cells (from the Greek word meiosis meaning “diminution”) |
| penis | The male organ of copulation and urination (adjective: penile) |
| pituitary gland | A small endocrine gland at the base of the brain; the anterior lobe secretes growth hormone and hormones that stimulate other glands; the posterior lobe releases ADH and oxytocin manufactured in the hypothalamus (root: pituitar/i); hypophysis |
| prepuce | The fold of skin over the glans penis; the foreskin |
| prostate gland | A gland that surrounds the urethra below the bladder in males and contributes secretions to the semen (root: prostat/o) |
| puberty | Period during which the ability for sexual reproduction is attained and secondary sex characteristics begin to develop |
| scrotum | A double pouch that contains the testes (root: osche/o) |
| semen | The thick secretion that transports spermatozoa (roots: semin, sperm/i, spermat/o) |
| seminal vesicle | A sac-like gland behind the bladder that contributes secretions to the semen (root: vesicul/o) |
| Sertoli cell | Cell in a seminiferous tubule that aids in the development of spermatozoa; sustentacular (sus-ten-TAK-u-lar) cell |
| spermatic cord | Cord attached to the testis that contains the ductus deferens, blood vessels, and nerves enclosed within a fibrous sheath |
| spermatozoon | Mature male sex cell (plural: spermatozoa) (roots: sperm/i, spermat/o) |
| testis | The male reproductive gland (roots: test/o, orchi/o, orchid/o); plural is testes (TES-teze); also called testicle |
| testosterone | The main male sex hormone |
| urethra | The duct that carries urine out of the body and also transports semen in the male (root: urethr/o) |
| vas deferens | The duct that conveys spermatozoa from the epididymis to the ejaculatory duct; also called ductus deferens |
| benign prostatic hyperplasia (BPH) | Nonmalignant enlargement of the prostate; frequently develops with age |
| cryptorchidism | Failure of the testis to descend into the scrotum |
| epididymitis | Inflammation of the epididymis; common causes are UTIs and STIs |
| erectile dysfunction (ED) | Inability of the male to perform intercourse because of failure to initiate or maintain an erection until ejaculation; impotence |
| herniorrhaphy | Surgical repair of a hernia |
| impotence | Erectile dysfunction |
| infertility | Decreased capacity to produce offspring |
| inguinal hernia | Protrusion of the intestine or other abdominal organ through the inguinal canal or through the wall of the abdomen into the scrotum |
| orchitis | Inflammation of a testis; may be caused by injury, mumps virus, or other infections |
| prostatectomy | Surgical removal of the prostate |
| prostatitis | Inflammation of the prostate gland; often appears with UTI, STI, and a variety of other stresses |
| sexually transmitted infection (STI) | Infection spread through sexual activity; also called sexually transmitted disease (STD) and formerly venereal (veh-NE-re-al) disease (VD) (from Venus, the goddess of love) |
| sterility | Complete inability to produce offspring |
| urethritis | Inflammation of the urethra; often caused by gonorrhea and chlamydia infections |
| vasectomy | Excision of the vas deferens; usually done bilaterally to produce sterility; may be accomplished through the urethra (transurethral resection) |
