Presentation transcript:

 Forms new individuals  Species survival

 9-15 yrs old  Hypothalamus → pituitary → FSH and LH FSH: follicle-stimulating hormone LH: luteinizing hormone  FHS/LH Male: testosterone Females: estrogen  Sexual maturation

 Testis  Epididymis  Vas deferens  Urethra  Penis

 FSH + LH → testosterone in testis Testosterone: male sex hormone  FSH + testosterone → sperm in seminiferous tubles  Stored in epididymis and vas deferens  Path of sperm

 Gamete  Single cell  Semen (sperm and seminal fluid)

 Steroid  Female sex hormone  Produced in ovaries  Sexual maturation  Help prepare for pregnancy  Pregnancy

 Ovaries  Fallopian tubes  Uterus  Vagina

 Born with immature eggs  400 released in lifetime  Occurs in ovaries  Follicles help mature
