What to watch with Progesteron and allergy?

The relationship between progesterone and allergies is not well established. Progesterone, a key female hormone, can modulate immune responses—sometimes anti-inflammatory, sometimes potentially exacerbating allergic reactions, especially in women with cyclical allergy symptoms. Some mechanistic and small observational studies suggest links to histamine release, but evidence is weak. The provided context contains no direct data on progesterone and allergy. Consumer blood tests for progesterone (e.g., from MyBody-X) have limitations: levels fluctuate with menstrual cycle, and single measurements are not diagnostic. Allergy tests (IgE) may also be influenced by hormonal status. If you are using progesterone therapy (e.g., for HRT or fertility) and have allergies, consult a healthcare provider for personalized management. Evidence: unclear. Sources: none from context.
