Estrogen Resistance

Estrogen Resistance or Estrogen insensitivity syndrome or EIS is an extremely rare intersex trait only known to affect one person so far. Individuals with estrogen resistance have defective estrogen receptors (ER) and cannot achieve their goal.

The reported AMAB-CTM individual with EIS was abnormally tall, as estrogens were unable to act close to the epiphyseal line, and put them at risk for osteoporosis, and sterile, which suggest that in humans, estrogens are necessary for reproduction. One with this condition cannot impregnate anyone, as they are infertile.

Flag
The flag was coined by Mod Hermy through Pride-color-schemes Tumblr account on June 15th of 2017. It is made to represent an orchid, as orchids are often used as a symbol for intersex individuals.
