    Puberty usually begins around ages 10—11 in females and around ages 11—12 in males. [7] Body weight and nutrition status is evidenced to have an effect on puberty onset as well, due to some input from adipose tissue hormonal signaling. [8] Puberty involves both the processes of gonadarche and adrenarche. [6]

  5. Mini-puberty - Wikipedia

    en.wikipedia.org/wiki/Mini-puberty

    Mini-puberty is a transient hormonal activation of the hypothalamic-pituitary-gonadal (HPG) axis that occurs in infants shortly after birth. This period is characterized by a surge in the secretion of gonadotropins (LH and FSH) and sex steroids (testosterone in males and estradiol in females), similar to but less intense than the hormonal changes that occur in puberty during adolescence.

    These changes are largely influenced by hormonal activity. Hormones play an organizational role, priming the body to behave in a certain way once puberty begins, [16] and an active role, referring to changes in hormones during adolescence that trigger behavioral and physical changes. [17]

  7. Secondary sex characteristic - Wikipedia

    en.wikipedia.org/wiki/Secondary_sex_characteristic

    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.

    en.wikipedia.org/wiki/Hormone

    A hormone (from the Greek participle ὁρμῶν, "setting in motion") is a class of signaling molecules in multicellular organisms that are sent to distant organs or tissues by complex biological processes to regulate physiology and behavior. [1] Hormones are required for the correct development of animals, plants and fungi. Due to the broad ...
