#MOSTIMP POINTS OF MALE REPRODUCTIVE STRUCTURE
Testis→Mesodermal in origin
→Oval in shape 4-5 cm long , 2-3 cm wide and 3 cm thick
• Stages of spermatogenesis
Spermatogonial cell (2n) → Primary spermatocyte (2n) →
Spermatids (n) →Sperms (n)
× Interstitial/Leydig's cell secretes male hormone androgen
• Accessory ducts ||
Rete testis → vasa efferentia→epididymis →vasa deferens →ejaculatory duct →Urethta
Upper caput
• Epididymis Middle corpus
Lower coda
• Sperms undergoes maturation in epididymis
• Glands ||
1) seminal vesicle - secretes alkaline seminal fluid contains fructose , fibrinogen , prostaglandins
2) Prostate glands - secrets milky white & slightly acidic prostatic fluid into urethra
3) Bulbourethral gland - Secrets alkaline , viscous , mucus like secretion which help in lubrication
• Semen ||
pH - 7.2 to 7.7 [ 2.5 to 4.0 mL per ejaculation ] →approx 400 million sperms
