2010). Slight increase in resistin levels in the sham and endometriosis groups (nonsignificantly), which we have seen might be due to the inflammatory response to surgery (Asgeirsson et al. 2011). It should be considered that in our study resistin was measured in the serum, while its increase in the peritoneal fluid which has been reported is locally and could be in response to inflammation and metabolic disorder (Lehrke et al. 2004). The gene discussed is RETN; the disease is endometriosis.
