Bulbous urethra + Cowper’s glands
(bulbourethral)

Spermatogenesis
Testis (primary male sex organ)
Seminiferous tubules
Sperms
Spermatozoa
Spermatids
Secondary spermatocytes
Primary spermatocytes
Spermatogonia
Sertoli cells
Blood-testis barrier
Interstitial cells of Leydig (Leydig cells)
Androgen production & hormonal regulation
Testosterone VS Dihydrotestosterone (DHT)
Testosterone
Epididymis
Vas deferens
Seminal vesicles
Except prostate gland
Dihydrotestosterone (DHT)
Finasteride
5-reductase
Growth of prostate gland
Sebaceous gland activity
Actions of Androgens
Androgenic / Virilizing effects
Develop internal male sex organs
Male secondary sex characteristics
Increase libido & sperm synthesis
Anabolic effects
Increase red blood cells
Increase basal metabolic rate
Increase bone growth
Increase muscle mass
Hormonal Control & Feedback Regulation
Functions of Leydig & Sertoli cells
Leydig cells
Control by LH (or hCG)
Secrete androgens
Testosterone
Dihydrotestosterone (DHT)
Androstenedione (A4)
Sertoli cells
Secrete
Control by FSH
Support spermatogenesis
Male sexual responses
Erection
Parasympathetic
Nitric oxide
Lubrication
Bulbourethral and urethral glands secrete mucus
Parasympathetic
Emission
Emission (movement of semen into the urethra)
Sympathetic
Ejaculation (propulsion of semen out of the urethra)
