Questions Fully Solved Rated A+(2025-
2026) Edition.
male reproductive organs - Answer Primary: two testes
Secondary internal accessory: epididymides, ductus deferentia, seminal vesicles, prostate gland,
bulbourethral glands
Secondary external: scrotum, penis
functions of the male reproductive organs - Answer - to develop and maintain male sex cells
(sperm)
- to transport sperm and fluids to outside of body
- to synthesize male sex hormones
testes - Answer - produce sperm
- produce male sex hormones
- originate from masses of tissue behind the parietal peritoneum, when testosterone is
produced before birth they decent into the scrotum
structure of testes - Answer - tunica albuginea: tough, fibrous capsule enclosing each testis
- lobules: compartments in testis, separated by connective tissue septa
- seminiferous tubules: high coiled tubules inside lobules, lined with a stratified epithelium
containing spermatogenic cells that give rise to sperm cells
- interstitial cells (cells of leydig): lie between seminiferous tubules, produce and secrete male
sex hormones
- rete testis: channels that transport sperm from testis to epididymis
- epididymis: coiled tube on surface of testis that transports sperm from rete testis to ductus
deferens
epididymis - Answer - narrow tightly coiled tubes at top of each testis
- connected to ducts in the testis
- run between testis and ductus deferens
- promote maturation in sperm cells
, - part of spermatic cord
- each extends from the epididymis to the ejaculatory duct
- psuedostratified columnar epithelium
seminal vesicles - Answer - attached to a ductus deferens near base of the urinary bladder
- secrete alkaline fluid which regulates pH in male and female tracts
- secrete fructose and prostaglandins
- contents empty into ejaculatory duct
- contributes most of volume of semen
prostate gland - Answer - surrounds proximal portion of the urethra
- lies inferior to urinary bladder
- ducts of gland open into urethra
- composed of tubular glands in connective tissue
- contains smooth tissue
- secretes thin, milky alkaline fluid
- secretion enhances sperm motility
- contributes to volume of semen
bulbourethral glands - Answer - cowpers glands
- inferior to prostate gland
- secrete mucus like fluid into urethra
- fluid released in response to sexual stimulation
- lubricates end of penis
scrotum - Answer - pouch of skin and subcutaneous tissue located behind penis
- dartos muscle: contracts and relaxes in response to temperature changes to keep testes at
optimal temperature for sperm production and survival
penis - Answer - conveys urine and semen through urethra to outside of body
- becomes erect for insertion into vagina during sex
