Introduction
This section gives a very brief overview of renal and 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).
Renal - Nephron Development
After nephron development has completed and concomitant with the development of the renal papilla in the newborn, the thin ascending limb of Henle’s loops is generated as an outgrowth from the S3 segment of the proximal tubule and from the distal tubule anlage of the nephron.[1] (birds and mammals)
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[2]
