Evaluation of daily supplementation of fertitonex on different semen parameters in idiopathic male infertility: a randomized double blind placebo controlled cross over study

Purpose The study aimed to evaluate the effect of fertitonex containing L-carnitine L-tartrate together with other micronutrients on different semen parameters in idiopathic male infertility as well as male reproductive hormones. Methods 100 randomized infertile patients were recruited from July 2023 to February 2024. They were randomized into two groups. Group (A) received fertitonex twice daily for the first 3 months. Group (B) received placebo twice daily for the first 3 months. Crossover was done after 1 month wash-out period for additional 3 months. Results Group (A) who started fertitonex first showed significant improvement in sperms concentration and motility and progressive motility as well as significant reduction in abnormal forms after 3 months from beginning the study (p < 0.001, p < 0.001, p < 0.001, p < 0.001, respectively). Interestingly, these improvements continued for additional 3 months after placebo intake (p < 0.001, p 0.005, p < 0.001, p < 0.001, respectively). Group (B) who started placebo first showed significant improvement in sperms concentration and motility and progressive motility as well as significant reduction in abnormal forms after 6 months from beginning the study (p < 0.001, p < 0.001, p < 0.001, p < 0.001, respectively). LH level was significantly higher among group (A) compared to group (B) at baseline and 3 months and 6 months (p value 0.02, 0.032. 0.024, respectively). Conclusion We finally concluded that fertitonex is an effective, tolerable and safe drug that can be used for treating idiopathic male infertility.
