Inadequate luteal phase and benign breast disease.

The Authors compare E2 and Progesterone plasma levels in the luteal phase of twelve normally menstruating women whose basal body temperature curves were biphasic and in which breast micronodularity and mastodynia were present, with those of ten breast disease-free controls. The significant difference (p less than 0.001) found in Progesterone levels gives strength to the opinion that Progesterone supply therapy can effectively improve both mastodynia and the clinical picture objectively documented.
