Puberty• HORMONES: substances that act in the body like
messengers• PUBERTY: period of time in the mid teens when
reproductive hormones signal the body so can prepare for reproduction
• Pituitary gland in brain releases follicle stimulating hormone (FSH) to the gonads (ovaries and testes) to tell them to produce gametes (eggs and sperm)
• Testosterone in males and estrogen in females signals development of SECONDARY SEX CHARACTERISTICS such as hair growth, body structure changes, voice changes

Male Reproductive System• Designed to produce as many healthy sperm as
possible • TESTES: produce sperm cells, located outside of the
body in a sac called the SCROTUM• Sperm need to be slightly cooler than the rest of the
body so the scrotum can move to stay at ideal temperature
• SEMINIFEROUS TUBULES: produce about 350 to 500 million sperm a day
• EPIDIDYMIS: coiled tube take takes the sperm out of the testes and into the body
• The epididymis enters the body and is then called the VAS DEFERENS, this takes the sperm in a loop around the bladder

Male Reproductive System 2• PROSTATE GLAND and SEMINAL VESICLES add
thick sugary fluid to the sperm to provide energy for the sperm to swim
• SEMEN: sperm + sugary fluid from prostate gland and seminal vesicles
• URETHRA: tube through the center of the penis that carries sperm and urine outside the body
• Vas deferens joins the urethra• A muscular valve prevents urine and sperm from
exiting at the same time• Sperm has a head with a nucleus inside, a hat filled
with enzymes and a tail for swimming
