Puberty is the process of aquiring reproductive capability. The onset depends on the ability of specific hypothalamic neurons to produce GnRH in sufficient quantities to both promote and support gametogenesis.
- In the female, hypothalamic GnRH neurons must develop the ability to respond to positive oestradiol feedback in order to produce sufficient GnRH to cause ovulation.
- Develepment of hypothalamic neurons is influenced by:
- Development of a threshold body size.
- Exposure to environmental and social cues.
- Genetics
