Introduction
This section gives a very brief overview of genital postnatal changes that occur in neonatal, childhood and through to puberty. For sexual development at puberty, we will use resources available online from Endocrinology: An Integrated Approach (NCBI Bookshelf).
Newborn
Puberty
Latin, pubertas = "adulthood"
In the teen years the endocrine changes that signal sexual development trigger changes in primary sex organs and the development of secondary sexual characteristics.
Puberty can occur over a broad range of time and differently for each sex:
|
- Links: Puberty Development | Tanner stages
Female - Hypothalamus Pituitary Gonad (HPG) Axis
Male - Testosterone
Male Testosterone and Anti-Müllerian Hormone (AMH) relative levels[1]
