The researchers think that the supplements may have an antioxidant effect in the testes. The FSH and LH levels, on the other hand, went down. The supplements had a positive effect on the sperm quantity, motility and the number of sperm cells. NAC group took 600 milligrams of N-acetyl-cysteine. Doctors had already determined that they had a low sperm count or that they had low quality sperm cells. Read summaries of the latest studies across 25 categories, or pick the categories that matter most to you. Combination therapy and NAC did not affect blood testosterone levels. While testosterone levels were higher in the TAD Group, no statistically significant difference was found between the groups. We advocate their use for male infertility treatment. The hypothetical action of NAC originates from its ability to stimulate and sustain intracellular levels of reduced glutathione and also to detoxify ROS . 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) In physiological conditions, spermatozoa produce little ROS, which are required for sperm physiology (sperm hyperactivation, capacitation, acrosome reaction) and also for natural fertilization . Many environmental, physiological, and genetic factors have been implicated with sperm functions and infertility . ROS may have either endogenous or exogenous origin and may cause defective spermatogenesis and male infertility . Oxidative stress markers, i.e. total antioxidant capacity (TAC) and malondialdehyde (MDA), as well as hormonal profile (LH, FSH, Testosterone and Prolactin) were determined by ELISA kit. Mona et al. showed that NAC administration before the chemotherapy could improve reproductive functions and the gonadal hormone disturbance in female rats through its protective effects against oxidative stress(Reference Helal30). However, the elimination of publication bias using trim and fill analysis revealed that NAC also could decrease E2 levels and endometrial thickness. Sensitivity analysis demonstrated that the overall effect size regarding the effects of NAC on LH did not depend on one individual study. Subgroup analyses for the effects of N-acetylcysteine on ovulation and sex hormones profile (95 % confidence intervals) In the presence of publication bias, trim and fill analysis was used to simulate a model without publication bias presenting a new effect size by inserting new fictitious studies. Considering several benefits of NAC in patients with PCOS, there is still unresolved controversy among clinical trials investigating the efficiency of NAC supplementation in improving ovulation and sex hormones profile in PCOS patients. In addition to searching in databases, we checked the references of related articles for any missing eligible articles (hand-search method). A systematic search was conducted in the international scientific databases, including PubMed, Embase, Web of Science, Scopus and Cochrane Central Library, for relevant studies published up to September 2021. On the other hand, NAC might increase the chance of pregnancy(Reference Maged, Elsawah and Abdelhafez8,Reference Hassan, Alalfy and Hassan18) . Thus, reducing insulin resistance is an efficient approach in these patients(Reference Carmina and Azziz17). Also, serum levels of oestradiol (E2) and progesterone were improved in PCOS women after NAC consumption(Reference Nasr9). Treatment with NAC induces ovulation, decreases miscarriage rates and increases live birth rates(Reference Nasr9).
