Our experience of application of low-level laser therapy in red spectrum in male idiopathic secretory infertility

Introduction. Due to insufficient efficacy of medical therapy of idiopathic secretory male infertility there is a need to develop and apply more resultative methods of treatment. The aim of our study was to assess the efficacy of low-level laser therapy (LLLT) in red spectrum on sperm parameters, sperm DNA fragmentation (SDNAF) and MAR-test rate in men with idiopathic infertility. Patients and methods. 85 men with idiopathic infertility were examined, 50 of them (first group) were treated with LLLT and 35 (second group) didnt have course of LLLT. Average age of patients of the first and second groups was 31.4 1.3 and 32.3 1.4 years. LLLT was performed in red spectrum on a Rubin-C device (Russia). 10 laser therapy procedures were carried out every two days with active luminescence for 10 minutes of both testicles. Male hormone panel, semen analysis, MAR-test, SDNAF were assessed before and after the treatment. Results. LLLT in patients of the first group resulted in significant increase in ejaculate volume, sperm viability, number of morphologically normal sperm forms (by an average of 11, 9 and 23% respectively), and active mobile sperm forms by an average of 14 and 19% one and two months after the therapy respectively. In 12 patients of the first group with initially increased SDNAF its level became normal after the treatment. Significant decrease of MAR-test we searched out in patients of the first group with its initial level less than 30%. As a result of the treatment, pregnancies developed in 10 (20%) out of 50 couples in the first group. Conclusions. LLLT in red spectrum leads to significant improvement of sperm quality in patients with idiopathic infertility, normalizes sperm DNA-fragmentation level and decreases MAR-test level.

The aim of study was to assess the effect of low-level laser therapy (LLLT) in infrared spectrum on the main sperm parameters, sperm DNA fragmentation, MAR-test in men with nonobstructive pathozoospermia. Patients and methods. The study included 50 men from 23 to 40 years old (average age 31.0 5.4), suffering from secretory infertility. Physical examination, semen analysis, MAR-test, sperm DNA fragmentation analysis, male hormone panel, assessment of prostate microbiocenosis, testes and prostate tumor markers, ultrasound examination with color flow mapping were performed. After the examination patients had a course of LLLT in infrared spectrum on a Rubin-C device. 10 laser therapy procedures were carried out every two days with active luminescence for 3 minutes of both testicles. Control examination was done immediately after the LLLT, within one and two months. Results. Increase in sperm concentration (by an average of 25%), active mobile sperm forms (by an average of 25%), morphologically normal sperm forms (by an average of 58%) was noticed after the LLLT. MAR-test decreased by an average of 69% after the therapy. From 10 patients with initially increased sperm DNA fragmentation level, in 9 patients its level became normal after the treatment. Increase in concentration of total and free testosterone in blood plasma was noticed within one month after the LLLT. As a result of the treatment pregnancies developed in 11 (22%) out of 50 couples. Conclusions. LLLT in infrared spectrum improves sperm quality in patients with secretory infertility, decreases MAR-test level, normalizes sperm DNA-fragmentation level, increases chances of pregnancy in reproductive cycle, which allows to recommend this method as preparation for assisted reproductive technologies.

INTRODUCTION: Autoimmune infertility is diagnosed in 515% of men. Currently applied methods of medical therapy of autoimmune male infertility are not very effective, which requires the development of new ones and creation of predictive algorithms for their efficacy. The aim of our study was to evaluate the influence of low-level laser therapy (LLLT) in infrared spectrum on MAR-test rate and sperm fertile properties in men with autoimmune infertility, develop ways to predict the efficacy of this therapy. PATIENTS AND METHODS: 47 men with autoimmune infertility were examined. 31 of them (1st group) underwent course of LLLT in infrared spectrum (10 procedures), and 16 patients (2nd group, comparison) had placebo-laser therapy sessions (10 procedures). MAR-test value, main semen parameters and sperm DNA fragmentation were assessed before and after the treatment. For creation of LLLT efficacy algorithm we used discriminate analysis. RESULTS: In patients of the 1st group we indicated statistically significant decrease of MAR-test by an average of 19% immediately after the course of procedures, and by 33% within two months after the end of the treatment, at its initial level 60% or lower. LLLT contributed to improvement of the semen fertile properties, pregnancy developed in the natural reproductive cycle in 19% of couples. We developed math model for prediction the efficacy of LLLT in infrared spectrum of autoimmune male infertility. CONCLUSION: LLLT in infrared spectrum of male autoimmune infertility leads to MAR-test value decrease at its initial level less than 60%; improves sperm fertile properties. It is appropriate to use before LLLT predictive algorithm of its efficacy developed by us.

The purpose of this study was to evaluate whether Low-Level Laser Therapy (LLLT) improves the healing of the implant surgical site with clinical and biochemical parameters.Thirty patients with an edentulous space spanning a single tooth were selected. The patients were randomly allocated to two groups - the control group and the test group. The test group received laser energy at a power of 2J/cm 2 with a total of 4-6J energy over each implant. Clinical parameters (Implant Stability Quotient, probing index, modified sulcus bleeding index)and osteoprotegerin (OPG) were assessed at baseline and follow-up intervals (2 weeks, 6 weeks, and 3 months).The test group showed significantly higher implant stability quotient compared to thecontrol group at 2 weeks(57.93±3.95 and 35.67±3.08; p<0.01) and 3months(58.86±3.75 and 67.06±3.78; p<0.01). A significant rise in OPG levels of the test group(686.30±125.36pg/ml at baseline and 784.25±108.30pg/ml at 3months;p<0.01) was seen contrary to significant decline in the control group (839.50±249.08pg/ml at baseline,415.30±78.39pg/ml at 3months;p<0.01). Within the limitations of the study, the study suggests that the healing of peri-implant hard and soft tissues may be enhanced with the use of LLLT as an explicit modality during the post-operative period.
