Hormonal Onset of Puberty

• At puberty the hypothalamus secretes a releaser hormone that targets the pituitary gland
• Releaser hormones cause the release of other hormones to start and stop
• The pituitary gland is stimulated to release

  • follicle stimulating hormone (FSH)

  • Luteinising hormone (LH) in women

  • Or interstitial cell stimulating hormone (ICSH) in men

  • These hormones control the onset of puberty
