Breast enlargement

{{Short description|Techniques to increase the size of human breasts}}

Breast enlargement is the enlargement of the breasts. It may occur naturally as in mammoplasia or may occur artificially through active intervention. Many women regard their breasts, which are female secondary sex characteristics, as important to their sexual attractiveness, as a sign of femininity that is important to their sense of self. Due to this, when a woman considers her breasts deficient in some respect, she might choose to engage in some activity intended to enhance them.{{cite web|url=http://www.sexarchive.info/ATLAS_EN/html/secondary_characteristics.html |title=Secondary sex characteristics |publisher=.hu-berlin.de |access-date=2011-10-31}}

Actual and potential methods to achieve larger breasts include:

• Surgical breast augmentation, such as with breast implants or fat transfer.
• Pharmacological or hormonal breast enhancement, through administration of medications such as estrogen or breast enlargement supplements.{{cite book|author1=Gunther Göretzlehner|author2=Christian Lauritzen|author3=Thomas Römer|author4=Winfried Rossmanith|title=Praktische Hormontherapie in der Gynäkologie|url=https://books.google.com/books?id=TIs2WhfYzZ4C&pg=PA385|date=1 January 2012|publisher=Walter de Gruyter|isbn=978-3-11-024568-4|pages=385–}}{{cite book|author1=R.E.

• Increasing the food energy intake by eating more and/or more energetic foods. By increasing food energy intake, more adipose tissue will be created, part of which will consist of adipose tissue located near the breast area.{{cite journal| pmid=7416252 | doi=10.1002/ajpa.1330530113 | volume=53 | issue=1 | title=Contribution of breast volume and weight to body fat distribution in females | date=July 1980 | journal=Am.

• Mechanical breast enhancement.{{cite journal|last1=Schlenz|first1=Ingrid|last2=Kaider|first2=Alexandra|title=The Brava External Tissue Expander: Is Breast Enlargement without Surgery a Reality?|journal=Plastic and Reconstructive Surgery|volume=120|issue=6|year=2007|pages=1680–1689|issn=0032-1052|doi=10.1097/01.prs.0000267637.43207.19|pmid=18040206|s2cid=45740913 }}
