Glutathione also acts as an antioxidant, neutralizing inflammatory molecules called free radicals or ROS that can damage cellular structures. Glutathione is a tripeptide composed of three amino acids, glutamate, glycine, and cysteine. NAC supports detoxification primarily through its role as a precursor to glutathione, a powerful antioxidant involved in the body's natural detoxification processes. NAC is used as a precursor for glutathione and possesses both antioxidant and mucolytic properties. However, if the body experiences a deficiency in these precursor amino acids, cysteine becomes essential and must be obtained through dietary sources. This designation implies that the body can synthesize cysteine from two other amino acids, namely serine and methionine. Oxidative stress may lead to dysfunction in endocrine glands, contributing to hormone imbalances (13, 27). Hormones are also metabolized and eliminated through these systems, emphasizing the important role of the liver in maintaining optimal hormone balance (19). Antioxidant defenses work in tandem with these pathways, neutralizing ROS, safeguarding the liver from oxidative stress, and maintaining overall cellular health. This delicate equilibrium is influenced by hormone production, transport, and metabolism. This study was approved by the ethics committee of the Azad Medical University. RJ, MN, KP and NH contributed in conception, design, statistical analysis and drafting the manuscript. The primary data for this study is available from the authors upon direct request. The association between sperm DNA damage and ROS is the basis for the use of antioxidants in the hope of reducing sperm DNA damage. N-acetylcysteine (NAC) is a thiol-based antioxidant that plays an important role in the protection of cellular constituents against oxidative damage. Based on our findings and other studies 19, 22, medical therapy with oral antioxidants can improve the quality of semen parameters. Correlation between sperm parameters and chromatin status with total antioxidant capacity (TAC) and malondialdehid (MAD) After NAC treatment, sperm motility correlated positively with TAC and negatively with MDA. Mean of seminal MDA decreased significantly after treatment with NAC compared to before treatment. Conclusively, LC/LAC and NAC showed a greater improvement in sperm motility and normal morphology. We researched PubMed, EMBASE, and Cochrane Library databases and references to related articles. All authors were responsible for data collection, data analysis and data interpretation in the manuscript. The authors would like to thank the Clinical Research Development Unit of Baqiyatallah Hospital, for all their support and guidance during carrying out this study. Second, all possible subgroup and bias-controlling analyses were performed to obtain reliable results on the effects of NAC on the reproductive biomarkers. Therefore, future studies must focus on the proper design to diminish the possible sources of bias. Possible uses range from improving athletic performance to managing blood sugar levels and treating chronic lung problems. N-acetylcysteine (NAC) is a supplement that may help with various conditions. Statistical analysis was performed by the paired t-test. "Uncommon side effects of NAC supplements may include diarrhea, gas, nausea, stomach pain, indigestion, and heartburn," he says. NAC is generally well tolerated and rarely presents any side effects, Dr. Gladd says. "Furthermore, NAC may enhance male fertility by improving semen parameters," he adds. Several studies have investigated the effectiveness of NAC in the reproductive performance of females. However, the elimination of publication bias using trim and fill analysis revealed that NAC also could decrease E2 levels and endometrial thickness. Sensitivity analysis revealed that the overall effect size did not depend on one individual study. Subgroup analysis was not performed due to the low number of studies. Research directly investigating whether does NAC decrease testosterone? It directly neutralizes free radicals, reducing oxidative stress within the body. NAC works primarily by increasing glutathione levels. NAC’s range of benefits often overshadows concerns about its potential impact on testosterone. It’s a powerful antioxidant and precursor to glutathione, a crucial antioxidant produced within the body. No, NAC does not directly increase testosterone production. Does NAC directly increase testosterone production? Based on available evidence, the answer to the question, does NAC decrease testosterone? Its role is primarily supportive, helping the body recover and potentially aiding in the restoration of natural testosterone production. NAC is sometimes used during post-cycle therapy (PCT) due to its antioxidant and liver-protective properties. After a cycle of anabolic steroids, individuals often experience a suppression of their natural testosterone production. It’s best to start with a lower dose and gradually increase it as needed, monitoring for any side effects. Forest plots showing results in sperm parameters on the sperm motility.
