PPARG and endometriosis: The authors observed that rosiglitazone negatively influenced the induction of endometriosis as both post-treatment spherical volumes of lesions (64.00 mm3 (interquartile range (IQR): 354.42) vs. 41.60 mm3 (IQR: 37.87), p = 0.018) as well as explant weights were significantly smaller among animals treated with the PPAR-γ agonist.
