Male Reproductive System

Male Hormone Testosterone - Hormone that produces male secondary sex characteristics. Both physical and emotional changes. Produced in the testes LH: Causes the testes to produce testosterone / it comes from the pituitary gland

Emotional Changes Angry Say things they don’t mean to say Insecure or edgy

Physical Changes Increase in height Longer and heavier bones Broader shoulders Deep voice Hair growth Enlargement of the penis, scrotum, and testes Formation of sperm

Male Reproductive System Penis: male sex organ used for reproduction and urination Scrotum: a sac-like pouch that hold the testes. (regulate temperature) Testes: male reproductive gland that produces sperm. Seminiferous Tubules – part of the testes that produce the sperm Sperm: male reproductive cells Epididymis: place where sperm mature.

Male Reproductive System Vas Deferens: two long tubes that act as a passageway for sperm. Seminal Vesicles: two glands that secrete nourishing fluid & helps sperm to move Cowper’s Gland: Secretes a clear, lubricating fluid for sperm Prostate Gland: Gland that produces fluid to protect and keep sperm alive. Ejaculatory Duct: Short, strait tube that passes into the prostate gland and opens into the urethra.

Erection: penis swells with blood and elongates. Ejaculation: passage of semen from penis. (muscular contractions) Semen: sperm and fluids.

Others… Circumcision: removal of the foreskin from the penis Sterile: can not produce offspring Mumps can cause this after puberty Temperature of the testicles Hernia: intestine pushes into the scrotum Vasectomy: cut the Vas Deferens

What are the main functions of the male reproductive system? Produce the sperm Release the sperm to the female
