“…As already noted, the impact of He-Ne laser radiation (k = 632.8 nm) on the functional characteristics of spermatozoa from different species was the subject of numerous studies (15,24,27,28,30,35,36). The data on the photobiomodulation effect on the sperm using the radiation from laser and LED sources with other wavelengths in red spectral region (k = 620-630 (2,20-23), k = 630 nm (19), k = 635 nm (38), k = 637 nm (14), k = 647 nm (1), k = 650 nm (38), k = 655 nm (31,32), k = 660 nm (26,29), k = 670 nm (37)) can also be found in the literature. The effect of laser radiation in green spectral region (k = 532 nm) on spermatozoa is less studied (25,39).…”

“…Numerous studies performed with sperm from different species have shown that the radiation in visible spectral region (blue-green region: k = 470 nm (13), green: k = 532 nm (25,39), k = 490-540 nm (34); red: k = 620-630 (2,(20)(21)(22)(23), k = 630 (19), k = 632.8 (15,24,27,28,30,35,36), k = 635 nm (38), k = 637 nm (14), k = 647 nm (1), k = 650 nm (35), k = 655 nm (30,31), k = 660 nm (26,29), k = 670 nm (37)) and in near-infrared spectral region (k = 810 nm (16,19), k = 830 nm (12), k = 850 nm (14), k = 905 nm (11), k = 940 nm (10)), as well as broadband white light (k = 400-800 nm (17,18,27)), exerts a regulatory effect on spermatozoa.…”

“…At the present time, convincing evidences of the changes in the most important characteristics of spermatozoa exposed to light (motility, velocity, vitality, maintaining at a higher level the functional characteristics of spermatozoa during storage and their fertilization rate) have been obtained. The effects of photobiomodulation were reported upon irradiation of sperm from different species: mammals (human (1,(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19), boar (20)(21)(22), horse (2), donkey (23), bull (24)(25)(26)(27), ram (28,29), rabbit (30), dog (31,32), mouse (18,33,34)), birds (35,36) and hydrobionts (29,(37)(38)(39)(40). Changes in the functional characteristics of spermatozoa are induced by exposure to coherent laser radiation (1,9,11,12,15,16,19,(24)(25)…”

A comparative study of the effect of low‐intensity laser radiation in green (λ = 532 nm) and red (λ = 632.8 nm) spectral regions at equal average irradiance (3 mW cm−2) on functional characteristics of Siberian sturgeon spermatozoa is carried out. Confirmation of the photobiomodulation effect of the radiation is obtained by analyzing spermatozoa motility, percentage of motile spermatozoa and fertilization rate. It is shown that, depending on the energy dose, the laser radiation in red and green spectral regions can have both stimulatory and inhibitory effects on spermatozoa motility. Contrary to popular belief that the short‐wavelength radiation has great prospects in reproductive biotechnologies (due to more efficient absorption of radiation by cellular chromophores and increased generation of ROS), convincing evidence of a more pronounced stimulatory effect of radiation in the red spectral region was obtained. For the first time, metal‐free porphyrins capable of acting as endogenous photosensitizers generating ROS were detected and identified in animal sperm. Using luminol‐dependent chemiluminescence, it is shown that the increased production of ROS capable of exerting an inhibitory effect on biological systems at high concentrations is among the possible reasons for reduction in the stimulatory effect of radiation when moving from red to green spectral region.

“…In addition, the DNA fragmentation index (DFI) did not increase by NIR. 63 Based on various dose responses, it seems that shorter radiation of PMB with NIR compared to red light has more useful effects on the motility of sperm with no DNA damage in the sample of fresh and normal semen.…”

About 50% of infertility problems are related to male factors and reduced sperm motility. The important factor that affects the structure and function of sperm is reactive oxygen species (ROS), and over-concentration of ROS reduces the quality and motility of sperm. Photobiomodulation therapy (PBMT) using red to near-infrared (NIR) light is useful in oxidative stress restoration. It plays a therapeutic role in disorders such as asthenospermia, oligospermia cases, and cryopreserved sperm. It also enhances the metabolic capacity of sperm and increases the low-level and non-harmful intracellular content of Ca2+, nitric oxide (NO), and ROS in the stressed cells. Likewise, it modulates survival intracellular pathways and maintains the motility, viability, DNA, and acrosome integrity of sperm. This article reviews the state-of-the-art preclinical and clinical evidence regarding the efficacy of semen PBMT.

Multiple wavelength devices are now available for photobiomodulation (PBM) treatments, but their dosimetry for individual or combinatorial use remains unclear. The present work investigated the effects of 447, 532, 658, 810, 980 and 1064 nm wavelengths on odontoblast differentiation at 10 mW/cm2 using either equal treatment time for conventional fluence (300 seconds for 3 J/cm2) or varying times to adjust for individual wavelength photon fluence (4.6 p.J/cm2). Both 447 and 810 nm significantly increased alkaline phosphatase (ALP) activity, while 1064 nm showed reduced ALP activity at 3 J/cm2. However, ALP induction was significantly improved when equivalent photon fluence dosing was used. Other wavelengths did not show significant changes compared to untreated controls. The data suggest that accounting for wavelength‐specific photon energy transfer during PBM dosing could improve clinical safety and efficacy.
