Gonads – testicles – male sex glands – produce testosterone and sperm Seminiferous tubules – structures in testes were sex cell produced Epididymis – on back half of testes – stores sperm Urethra – tube that extends from bladder – joins w/ vas deferens Seminal Vesicle – releases clear, alkaline fluid – nourishes sperm w/ fructose – adds to mobility Prostate Gland – alkaline fluid – protects from acidic areas in urethra & vagina

5. MALE Cowpers Gland –(bulbourethral gland) lubricates urethra w/ clear viscous mucus Semen – ejaculated fluid - contains Sem V, Prostate, Cowper

6. Male Reproductive System

7. SPERM Acrosome – cap structure that covers the head – contains enzymes that help sperm locate and penetrate ova membrane Head – contains genetic material from male – 23 chromosomes Mitochondria – midpiece – helps supply energy – converts fructose from Sem. Ves Tail - movement -
