Abstract: Provided are methods of diagnosing a medical condition associated with hypersensitivity to a female reproductive hormone in a subject, with the proviso that the medical condition is not estrogen dermatitis. The method is effected by administering into a skin of the subject at least one female reproductive hormone such as estriol or estrone, and monitoring a reaction to the female reproductive hormone on the skin, wherein a presence of the reaction above a predetermined threshold is indicative of the presence of the medical condition in the subject. Also provided are methods and computing platforms for treating the medical conditions associated with the hypersensitivity to the female reproductive hormone by desensitization.
