Hypothyroidism, Oxidative Stress and Reproduction
In women, both hyperand hypo-thyroidism may result in menstrual disturbances. In hyperthyroidism the most common manifestations are simple oligomenorrhea and anovulatory cycles. Hypothyroidism results in changes in cycle length, amount of bleeding, and usually is associated with abnormal menstrual cycles characterized mainly by polymenorrhea and anovulatory cycles (Krassas et al., 1999). Also s...
متن کاملEnergy intake, oxidative stress and antioxidant in mice during lactation.
Reproduction is the highest energy demand period for small mammals, during which both energy intake and expenditure are increased to cope with elevated energy requirements of offspring growth and somatic protection. Oxidative stress life history theory proposed that reactive oxygen species (ROS) were produced in direct proportion to metabolic rate, resulting in oxidative stress and damage to ma...
متن کاملArsenic and Oxidative Stress in Pentylenetetrazole-induced Seizures in Mice
Background and Objective: Chronic arsenic toxicity is a widespread problem; the role of brain oxidative stress has been suggested in the genesis of epilepsy and in the post-seizure neuronal death. However, studies investigating the effects of arsenic on seizure and related mechanisms are limited. The purpose of this study was to examine the effect of prolonged exposure to sodium arsenite on oxi...
متن کاملOxidative Stress and Antioxidant Defense
Reactive oxygen species (ROS) are produced by living organisms as a result of normal cellular metabolism and environmental factors, such as air pollutants or cigarette smoke. ROS are highly reactive molecules and can damage cell structures such as carbohydrates, nucleic acids, lipids, and proteins and alter their functions. The shift in the balance between oxidants and antioxidants in favor of ...
متن کاملRole of oxidative stress in female reproduction
In a healthy body, ROS (reactive oxygen species) and antioxidants remain in balance. When the balance is disrupted towards an overabundance of ROS, oxidative stress (OS) occurs. OS influences the entire reproductive lifespan of a woman and even thereafter (i.e. menopause). OS results from an imbalance between prooxidants (free radical species) and the body's scavenging ability (antioxidants). R...
