Human Reproductive Systems

• Our species lives on.

2
Male Sexual Development

• Testosterone is the male reproductive hormone
• Secreted in small amounts until puberty
• Puberty begins when
• Hypothalamus ? Pituitary ? increased FSH AND LH
  ? GONADS (TESTES)
• GONADS ? TESTOSTERONE
• Testosterone produces male 2ndary sex
  characteristics

• Sperm produced
• Scrotum
• Protective sac around testes
• Keeps testes cool
• Epididymus
• Stores sperm while they mature

Female Sexual Development

• Estrogen is the female reproductive hormone
• Puberty begins when
• Hypothalamus ? Pituitary ? increased FSH AND LH
  ? GONADS (OVARIES)
• GONADS ? ESTROGEN
• Estrogen produces female 2ndary sex
  characteristics

8
Female Reproductive Parts

• Ovaries
• Female Reproductive Gland
• Eggs (ova) produced here
• Also contain follicles
• Place where eggs mature
• Fallopian tubes (Oviduct)
• Tubes that carry an egg from ovary to uterus
• Place of fertilization
• Uterus
• Mostly muscle
• Receives egg (fertilized or not)
