Breast enlargement may occur naturally through 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.
Methods used in an effort to achieve larger breasts include:
- Surgical breast augmentation, such as with breast implants or fat transfer.
- Hormonal breast enhancement, through administration of hormones such as estrogen and insulin-like growth factor 1 (IGF-1).
- Herbal breast enlargement supplements, pills or other ingested substances containing herbs asserted to increase breast size hormonally.
- Mechanical breast enhancement, such as through use of the BRAVA Breast Enhancement and Shaping System, a clinically-effective external breast tissue expander.
- Mark Eden bust developer, a fraudulently marketed method and device.
