Relaxes
2 ovoid glands, 2-3 cm Wide that lie in scrotum
Testes
Composed of several lobules containing
- Interstitial cells ( leydig cells

Responsible for the production of testosterone
Leydig’s cells
Testes in a fetus first form in
Pelvic cavity
Testes descend late in intrauterine life about _______, into scrotal sac
34 - 38th week
Testes that remain in pelvic cavity may not produce viable sperm and are associated with a 4-7 times higher incidence of testicular cancer
TRUE
Causes pituitary gland in brain to make and secrete hormones LH and FSH
Gonadotropin-releasing hormone
In men Lh and Fsh causes the testicle to make testosterone
True
Lh and FSH causes ovaries to make estrogen and progesterone
True
Beginning in ________ ___________ , boys need to learn ______ ____ _____ to detect tenderness or any abnormal growth in the testes
Early, Adolescence ——- Testicular Self Examination
Tube that carries away sperm from testes
Palpated as a firm swelling on the superior aspect of testes
Epididymis
Composed of three cylindrical masses of erectile tissue in the penis shaft
Penis
Two termed the
Corpus cavernosa
Third termed the
Corpus spongiosum
Outlrt for both urinary and reproductive tracts in men
Penis
Contracts trapping both Venous and arterial blood in three sections of erectile tissue and leading to distention and erection of penis
Ischeocavernosus muscle
A branch of pudendal artery, provides the blood supply for penis
Penile artery
Penile erection is stimulated by
Parasympathetic nerve innervation
Distal end of penis bulging, sensitive ridge of tisssue
Glans
Retractable casing of skin, protects the nerve sensitive glans at birth
Prepuce
Tightly coiled tube which is responsible for conducting sperm from the tubule to the vas deferens, the next step in the passage to outside
Epididymis
Epididymis is _____ ft long
20
It takes at least __________days for them to travel the length of epididymis and a total of _______days form them to reach maturity
