Puberty is the process of physical changes through which a child's body matures into an adult body capable of sexual reproduction.It is initiated by hormonal signals from the brain to the gonads: the ovaries in a female, the testicles in a male.
The following is a list of hormones found in Homo sapiens.Spelling is not uniform for many hormones. For example, current North American and international usage uses [citation needed] estrogen and gonadotropin, while British usage retains the Greek digraph in oestrogen and favours the earlier spelling gonadotrophin.
Among researchers who study puberty, the Tanner scale is commonly considered the "gold standard" for assessing pubertal status when it is conducted by a trained medical examiner. [5] In HIV treatment, the Tanner scale is used to determine which regimen to follow for pediatric or adolescent patients on antiretroviral therapy (adult, adolescent ...
Gonadarche marks the beginning of puberty and it is the process in which gonads, or the primary reproductive organs, mature, following stimulation of gonadotropin hormone-releasing hormone (GnRH) release in the hypothalamus. [6] The release of GnRH triggers a release of hormones that activate the maturation of the ovary and testis. [3]
Loss of function of LH receptors can cause male pseudohermaphroditism. In females mutations would have analogous effects. Hormone replacement can be used to initiate puberty and continue if the gene mutation occurs in the gene coding for the hormone. Chromosomal mutations tend to affect the androgen production rather than the HPG axis.
Starting puberty significantly early — younger than age 8 in girls, 9 in boys — may have health effects lasting into adulthood, including higher risks of breast cancer, diabetes and heart disease.
The Post also pointed to debate over puberty blockers in Europe, with "[m]ultiple European health authorities" reviewing scientific evidence for puberty blocker use in minors and "conclud[ing ...
An important sexual hormone of males is androgen, particularly testosterone. [6] The testes release a hormone that controls the development of sperm. This hormone is also responsible for the development of physical characteristics in men, such as facial hair and a deep voice.
