Does Estrogen Cause Big Lips?
Yes, higher estrogen levels are associated with fuller lips. This is supported by several studies and observations.
Multiple sources suggest a correlation between higher estrogen levels and fuller lips in women. This is believed to be a biological indicator of health and fertility, making full lips an attractive trait.
- Higher estrogen, fuller lips: One source explicitly states that "the higher the level of estrogen, the larger the eyes and the fuller the lips." [Source 1]
- Fertility indicator: Full lips are considered an evolutionary indicator of female fertility, linked to elevated estrogen levels. [Source 3, Source 8]
- Hormone Replacement Therapy (HRT): Some individuals report increased lip fullness as a result of HRT, suggesting a connection between estrogen levels and lip size. [Source 4]
- Labial Adhesions: Conversely, low estrogen levels, particularly in infants and toddlers, can cause labial adhesions (the inner lips of the vulva sticking together). [Source 3, Source 9, Source 10]
It's important to note that genetics and individual variation play a role in lip size. While estrogen influences lip fullness, it's not the sole determining factor.
Further Considerations
While the evidence strongly suggests a link between estrogen and lip fullness, it's crucial to remember that many factors contribute to facial features and that this relationship doesn't imply causation in every case. Lip size is a complex trait influenced by multiple genetic and hormonal factors.
