Oxidative Stress in Pregnancy.

Area of Science:

• Reproductive biology and toxicology
• Maternal-fetal medicine
• Biochemistry

Background:

• Pregnancy naturally increases susceptibility to oxidative stress (OS), characterized by elevated reactive oxygen species (ROS) and reactive nitrogen species (RNS).
• Elevated OS during pregnancy is linked to adverse outcomes including pre-eclampsia, intrauterine growth restriction, and fetal death.
• Trace elements like copper, zinc, manganese, and selenium are vital for the body's antioxidant defense mechanisms.

Purpose of the Study:

• To review the mechanisms of oxidative stress in pregnancy.
• To highlight the utility of oxidative stress markers in evaluating pregnancy complications.
• To discuss the role of animal models in studying pregnancy-related oxidative stress.

Main Methods:

• Review of existing literature on oxidative stress in pregnancy.
• Analysis of the role of specific trace elements in antioxidant defense.
• Examination of commonly used oxidative stress markers (e.g., MDA, SOD, GPx, GSH).

Main Results:

• Oxidative stress significantly impacts placental function and fetal development.
• Various oxidative stress markers provide indirect assessments of pregnancy complications.
• Animal models are essential for investigating the complex mechanisms of OS in pregnancy due to ethical and practical limitations in human studies.

Conclusions:

• Understanding oxidative stress mechanisms and utilizing appropriate markers are critical for managing pregnancy complications.
• Animal models offer valuable insights into the pathogenesis and potential interventions for pregnancy-related oxidative stress.
• Further research using these models can improve diagnostic and therapeutic strategies for adverse pregnancy outcomes.
