Male

• Organs and tissues
• testes, seminiferous tubules, epididymis, vas
  deferens, seminal vescicle, prostate gland
• Hormones
• testosterone, FSH, LH
• Spermatogenesis
• production of mature sperm by meiosis

Male Anatomy

• Epididymis
• Storage and maturation of spermatozoa
• Seminal Vesicle
• 60 of semen, high fructose content provides
  nourishment for sperm, alkaline
• Prostate Gland
• 25 of semen, high zinc content, alkaline,
  neutralizes acidic female tract

Testosterone

• Produced by cells in testes
• Embryonic secretion causes development of male
  sexual organs
• Secretion levels rise with onset of puberty
• Secondary sexual characteristics
• Pubic hair, growth of skeletal muscles, etc.

Structure of Testis

Sperm Production

• Termed spermatogenesis, a meiotic division
• Occurs in seminiferous tubules of testes
• Hormonal Control
• Follicle Stimulating Hormone (FSH) / pituitary
• Stimulates first division of meiosis (2n -gt n)
• Testosterone / testes
• Stimulates second division of meiosis
• Leutenizing Hormone (LH) / pituitary
• Stimulates secretion of testosterone
