Physiology of Puberty

Posted by e-Medical PPT Thursday, May 13, 2010
In humans, puberty is the process of physical changes by which a child's body becomes an adult body capable of reproduction. .During puberty, major differences of size, shape, composition, and function develop in many body structures and systems. The most obvious of these are referred to as secondary sex characteristics.
The onset of puberty is associated with high GnRH pulsing, which precedes the rise in sex hormones, LH and FSH. Exogenous GnRH pulses cause the onset of puberty. Brain tumors which increase GnRH output may also lead to premature puberty.
