Outline
  • Male Anatomy
  • Female Anatomy
  • Spermatogenesis
  • Oogenesis
  • Menstrual Cycle
  • Fertilization
  • Pregnancy and Childbirth

4
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

5
Male Anatomy
6
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

7
Epididymis

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
12
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

  • Hormones
  • estrogen, FSH, LH, progesterone, HCG, oxytocin
  • Egg production oogenesis
  • Menstrual cycle
  • Pregnancy, the placenta, and childbirth
