Fariba N, Paria P, Mehr A, Zohreh B, Hamid D., Histomorphological effects of Metformin, Pioglitazone, Repaglinide and Acarbose on polycystic ovaries in NMRI mice, Onl J Vet Res., 22 (10):919-927, 2018. Polycystic ovaries (PCO) were induced by injection of testosterone enanthate (TE) in 5 groups of 5 immature NMRI female mice each for 4 weeks then treated with Metformin, Pioglitazone, Repaglinide and Acarbose for 2-4 weeks. Five of these mice were testosterone PCO controls. Body and ovary/body weights were measured and microscopy of ovaries was evaluated. In PCO controls, we found numerous cystic follicles but reduced follicle growth. Compared with PCO controls, in those given metformin, body weights declined 17% ovary/body ratio weight 36% and ovarian diameter 38% (p<0.05). Pioglitazone induced similar effects (P < 0.05). In mice given Metformin, Pioglitazone and Repaglinide we found less oocytes, pyknosis and vascularization and fewer primordial, primary, antral, cystic and atretic follicles but more pre-antral follicles (p < 0.05). With all treatments we found less polycystic ovaries, degenerated oocytes, pycnosis and vascularization. Results suggest that Metformin and Pioglitazone best ameliorated polycystic ovary syndrome in NMRI mice.
