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
Average Ages of Puberty in the Male and Female of Various Species

|---|---|---|---|---|---|---|---|---|---|
| Male | 2-3 Years | 11 Months (7-18) | 3-5 Years | 9 Months (5-12) | 14 Months (10-24) | 9 Months (8-10) | 2-3 Years | 7 Months (6-9) | 7 Months (5-8) |
| Female | 1 Year | 11 Months (9-24) | 3 Years | 12 Months (6-24) | 18 Months (12-19) | 8 Months (4-12) | 6-12 Months | 7 Months (4-14) | 6 Months (5-7) |
