Chapter 15 - Male Reproductive System Flashcards
Any hormone that produces male characteristics; root andr/o means “male”
androgen
A small gland beside the urethra below the prostate that secretes part of the seminal fluid. Also called Cowper gland
bulbourethral gland
Sexual intercourse
coitus
Surgical removal of the end of the prepuce (foreskin)
circumcision
The duct that conveys spermatozoa from the epididymis to the ejaculatory duct. Also called vas deferens
ductus deferens
Ejection of semen from the male urethra
ejaculation
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
ejaculatory duct
A hormone secreted by the anterior pituitary that acts on the gonads.
follicle-stimulating hormone (FSH)
A coiled tube on the surface of the testis that stores sperm until ejaculation (root: epididym/o)
epididymis
The stiffening or hardening of the penis or the clitoris, usually because of sexual excitement
erection
A mature reproductive cell, the spermatozoon in the male and the ovum in the female
gamete
The bulbous end of the penis
glans penis
A sex gland; testis or ovary
gonad
Cells located between the seminiferous tubules of the testes that produce hormones, mainly testosterone. Also called cells of Leydig (LI-dig).
interstitial cells
The channel through which the testis descends into the scrotum in the male
inguinal canal
The type of cell division that forms the gametes; it results in cells with 23 chromosomes, half the number found in other body cells
meiosis
The male organ of copulation and urination (adjective: penile)
penis
A hormone secreted by the anterior pituitary that acts on the gonads
luteinizing hormone (LH)
An endocrine gland at the base of the brain
pituitary gland
The fold of skin over the glans penis; the foreskin
prepuce
A gland that surrounds the urethra below the bladder in males and contributes secretions to the semen (root: prostat/o)
prostate gland
Period during which the ability for sexual reproduction is attained and secondary sex characteristics begin to develop
puberty
The thick secretion that transports spermatozoa (roots: semin, sperm/I, spermat/o)
semen
A double pouch that contains the testes (root: osche/o)
scrotum
A sac-like gland behind the bladder that contributes secretions to the semen (root: vesicul/o)
seminal vesicle
Cord attached to the testis that contains the ductus deferens, blood vessels, and nerves enclosed within a fibrous sheath
spermatic cord
Cell in a seminiferous tubule that aids in the development of spermatozoa; sustentacular (sus-ten-TAK-u-lar) cell
Sertoli cell
Mature male sex cells (plural: spermatozoa) (root: sperm/i, spermat/o)
spermatozoon
The male reproductive gland (plural is also called testicles)
testis
The main male sex hormone
testosterone
The duct that carries urine out of the body and also transports semen in the male
urethra
The duct that conveys spermatozoa from the epididymis to the ejaculatory duct. Also called ductus deferens
vas deferens
Erectile dysfunction is also known as:
impotence
Decreased capacity to produce offspring
infertility
