What happens to your body during Puberty?

Biological events at puberty are set in motion by the onset of pursatile activity in the hypothalamic-anterior pituitary axis.In turn,this pursatile,or bursting activity causes the testes and ovaries to secrete their respective sex hormones, testosterone and estrogen that are responsible for the development of secondary sexaul characteristics.

Pulsability of the hypothalamic-pituitary axis is required for normal reproductive function as illustrated by the treatment of person with delayed puberty caused by GnRH deficiency.

In boys, Puberty is associated with activation of the hypothalamic-pituitary axis,leydig cell proliferation in the testis and increased synthesis and secretion of testosterone by the Leydig cells.There is growth of the testes,largely because of an increased number of seminiferous tubule.There is growth of the sex accessory organs such as the prostate.There is pronounced linear growth spurt and the epiphyses close when the adult height is attained.
