ABSTRACT
BACKGROUND: The aim of this study was to investigate the effects of the antioxidant supplement of CoQ10 and placebo in the male infertility treatment. MATERIALS AND METHODS: The randomized controlled trial study was designed as a clinical trial. Samples in each group consisted of 30 members. The first group received 1 daily dose of 100 mg coenzyme Q10 capsules and the second group received a placebo treatment. Treatment in both groups lasted 12 weeks. Before and after the intervention of semen analysis, hormonal measurement of testosterone, prolactin, luteinizing hormone (LH), follicle-stimulating hormone (FSH) and thyroid stimulating hormone (TSH) were done. Sexual function was assessed before and after the intervention by using the International Index of Erectile Dysfunction questionnare. RESULTS: The mean age of participants was 34.07 (5.26) years in the CoQ10 group and 34.83 (6.22) in the placebo one. Normal volume of semen (P=0.10), viscosity (P=0.55), sperm count (P=0.28), and sperm motility (P=0.33) in the CoQ10 group increased without statistically significant differences. But the normal sperm morphology increased with statistically significant differences in the CoQ10 group (P=0.01). There was an increase in normal FSH levels and testosterone levels in the CoQ10 group compared with the placebo patients, but these differences were not statistically significant (respectively P=0.58, P=0.61). The results also revealed that the scores of erectile function (P=0.95), orgasm (P=0.86), satisfaction with sexual intercourse (P=0.61), overall satisfaction (P=0.69) and the score of the International Index of Erectile Function (IIEF, P=0.82) were greater after the intervention in the CoQ10 group than in the placebo group although the difference was not statistically significant. CONCLUSION: The use of CoQ10 supplement can improve sperm morphology; however, in other sperm parameters and also in some hormones increased after the intervention, this was not statistically significant and therefore the result is not conclusive (registration number: IRCT20120215009014N322).
ABSTRACT
Objective: The purpose of this study is comparison of carob with placebo in the treatment of male infertility. Materials and methods: This study was performed as a clinical trial with two-group pretest-posttest design. Each group consisted of 30 members. The first group received 1.5 grams of carob per day, and the second group received placebo treatments. Treatment lasted for 12 weeks. Semen analysis as well as testosterone, prolactin, (LH), (FSH) and (TSH) were performed before and after drug treatment in two groups. Sexual function was assessed in the groups in two stages before and after the intervention using the standard International Index of Erectile Function. P-value less than 0.05 was considered statistically significant. Statistical analysis of data was performed using SPSS 16. Results: The participants' mean age was 34.83 ±6.22 in the placebo and 33.67 ±5.82 years in the Carob group. The results showed in the carob group compared to the placebo group, the rate of normal sperm counts increased by 17% and also the normal level of testosterone was 40% higher than the abnormal levels of the placebo group and these differences were statistically significant (P <0.05). And in most areas of sexual function, the mean scores after the intervention were higher than before (P> 0.05). Conclusion: It is recommended to use carob supplements to improve spermogram parameters and male sex hormones.
