Introduction: Currently, infertility is a main concern, and it is estimated that 15% of couples are considered infertile. Conventional therapies such as vitamins, antioxidants and supplements have been used widely, but they may not be sufficiently effective. This study evaluated the effect of laser acupuncture on semen parameters in infertile patients with oligospermia.
Methods: This study is a clinical trial with a double-blind control group. 35 patients in the intervention group underwent laser acupuncture twice a week for consecutive 5-weeks. In the control group, sham laser acupuncture was performed. The two groups were compared in terms of semen parameters including semen volume, sperm concentration, sperm motility and sperm morphology as the primary outcome. The secondary outcome was a successful pregnancy rate. After data collection, statistical analysis was performed with SPSS version 20.
Results: The mean age of all patients was 27.46±2.88 years; in the intervention group, their age was 27.82±2.6 years, and in the control group, it was 27.11±2.96 years, and there was no significant difference (P=0.396). During the study, 4 patients (5.4%) reported adverse effects; three patients in the control group complained of mild weakness and itching, and one patient in the intervention group reported dizziness. The volume of semen and sperm morphology did not differ significantly in both control and intervention groups (P ˃ 0.05), while sperm motility and sperm concentration had a significant difference (P=0.0001).
Conclusion: Laser acupuncture as a non-invasive procedure is effective in improving sperm mobility and concentration in infertile patients with oligospermia. Due to the surface contact of the laser probe with the skin and the lack of need to insert needles in the skin, laser acupuncture is more convenient and better tolerated by patients.
