Metyrosine attenuated ovarian IR injury in rats; hypothesis-generating and should not yet change practice.
The aim of this study is to investigate the effect of metyrosine on ischemia-reperfusion (I/R) induced ovarian injury in rats in terms of biochemistry and histopathology. Rats were divided into: ovarian I/R (OIR), ovarian I/R+50 mg/kg metyrosine (OIRM) and sham (SG) operations. OIRM group received 50 mg/kg metyrosine one hour before the application of the anesthetic agent, OIR and SG group rats received equal amount of distilled water to be used as a solvent orally through cannula. Following the application of the anesthetic agent, ovaries of OIRM and OIR group rats were subjected to ischemia and reperfusion, each of which took two hours. This biochemical experiment findings revealed high levels of malondialdehyde (MDA) and cyclo-oxygenase-2 (COX-2) and low levels of total glutathione (tGSH), superoxide dismutase (SOD) and cyclo-oxygenase-1 (COX-1) in the ovarian tissue of OIR group, with significant histopathological injury. In metyrosine group, MDA and COX-2 levels were lower than the OIR group whereas tGSH, SOD and COX-1 levels were higher, with slighter histopathological injury. Our experimental findings indicate that metyrosine inhibits oxidative and pro-inflammatory damage associated with ovarian I/R in rats. These findings suggest that metyrosine could be useful in the treatment of ovarian injury associated with I/R.

Yapça et al. (2023) studied Ischemia-reperfusion (I/R) induced ovarian injury. Metyrosine vs. Distilled water (OIR group) and sham operation was evaluated on Biochemical markers (MDA, COX-2, tGSH, SOD, COX-1) and histopathological injury. Metyrosine administration prior to ischemia-reperfusion reduced ovarian oxidative and pro-inflammatory damage, lowering MDA and COX-2 while increasing tGSH, SOD, and COX-1 levels in rats.
