How does puberty affect the male and female reproductive systems?
The onset of puberty is within 9 to 14 years of age in males and between 8 to 13 years of age in females. It begins with the secretion of GnRH by the hypothalamus. The gonadotropin-releasing hormone affects pituitary gland to secrete FSH and LH. These hormones regulate the function of reproductive organs and stimulate the production of testosterone in testicles, as well as estrogen and progesterone in ovaries. The puberty ends when secondary sexual characteristics occur. At this point begin the period of adolescence.
