Explain Thelarche, Define Thelarche, Meaning of Thelarche • Created on: 2018-12-31 • Source Link: https://en.wikipedia.org/wiki/Thelarche • ------ • Description: Thelarche is the onset of secondary breast development, usually occurring at the beginning of puberty in girls. Its etymology is from Greek θηλή , “nipple” and ἀρχή , “beginning, onset”. Thelarche is usually noticed as a firm, tender lump directly under the centre of the nipple . Thelarche is also referred to as a breast bud , or more formally as Tanner stage 2 breast development . Thelarche may occur on one side first, or both sides simultaneously. Thelarche is the first physical change of puberty in about 60 percent of girls, usually after 8 years of age. It is a result of rising levels of estradiol. It is typical for a woman's breasts to be unequal in size, particularly while the breasts are developing. Statistically it is slightly more common for the left breast to be the larger. In rare cases, the breasts may be significantly different in size, or one breast may fail to develop entirely. Although breast development can occur as a part of normal male puberty, it is termed gynecomastia, and the term thelarche is not used with reference to male breast development. When thelarche occurs at an unusually early age, it may be the first manifestation of precocious puberty. If no other changes of puberty or sex hormone effects occur, it is referred to as isolated premature thelarche, and generally requires no treatment. • ------ • To see your favorite topic here, fill out this request form: https://docs.google.com/forms/d/e/1FA... • ------ • Source: Wikipedia.org articles, adapted under https://creativecommons.org/licenses/... license. • Support: Donations can be made from https://wikimediafoundation.org/wiki/... to support Wikimedia Foundation and knowledge sharing.
