Q

What are the functions of oestradiol?

A
  • Supports female secondary sexual characteristics and reproductive organs
  • Negative feedback control of LH and GnRH (except for latel follicular phase)
  • Stimulates proliferative endometrium
  • Negative control of FSH

Q

Name the target organs for testosterone and what are the effects?

A
  • Skin: hair growth, balding and sebum production
  • Brain: libido and mood
  • Muscle: increase in strength and volume
  • Kidneys: stimulation of erythropoietin production
  • Bone Marrow: stimulation of stem cells
  • Bone: accelerated linear growth closure of epiphyses
  • Male Sexual Organs: penile growth, spermatogenesis, prostate growth and function
  • Liver: synthesis of serum proteins
