Two of the most significant differences between puberty in females and puberty in males are the age at which it begins, and the major sex steroids involved, the androgens and the estrogens. Although there is a wide range of normal ages, females typically begin the process of puberty around age 10½ and end puberty around 15–17; males begin ...
Despite the apparent necessity of GH/IGF-1 signaling in pubertal breast development however, women with Laron syndrome, in whom the growth hormone receptor (GHR) is defective and insensitive to GH and serum IGF-1 levels are very low, puberty, including breast development, is delayed, although full sexual maturity is always eventually reached.

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]
As puberty begins and sex hormone levels rise, differences appear, though some changes are similar in males and females. Male levels of testosterone directly induce the growth of the genitals, and indirectly (via dihydrotestosterone (DHT)) the prostate. Estradiol and other hormones cause breasts to develop in females.
Research on women and testosterone has been limited, but as more is done, experts are seeing that the hormone affects the female sex drive, just as it does the male. It also plays an essential ...
Male development can only occur when the fetal testis secretes key hormones at a critical period in early gestation. The testes begin to secrete three hormones that influence the male internal and external genitalia: they secrete anti-Müllerian hormone (AMH), testosterone, and dihydrotestosterone (DHT). Anti-Müllerian hormone causes the ...
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 ...
