Puberty
Biological changes that occur during youth and prepare the individual for sexual reproduction
Growth spurt hormones
Growth hormone and thyroid stimulating hormone
Growth hormone
Acts on all cells, increases cell size and number. Plateaus after puberty and decreases with old age.
Thyroid stimulating hormone
Increases in cell size and number. Brain maturation
Sexual maturation hormones
Follicle stimulating hormone, lutenising hormone and andrenocorticotrophic hormone
Follicle stimulating hormone-females
Triggers the ovaries to produce oestrogen, which causes the menstrual cycle and secondary sex characteristics to occur in females
Follicle stimulating hormone-males
Triggers the testes to produce sperm
Lutenising hormone-females
Triggers the ovaries to produce progesterone, which causes the menstrual cycle to occur in females
Lutenising hormone-males
Triggers the testes to produce testosterone which causes the male sex characteristics to occur
