Effect of Green Laser on Human Sperm Agglutination

Abstract

Infertility is a problem need to solve, many researchers and fertility doctors work hard for this purpose, and for this reason many different techniques tend to use to solve it. One of the most important one is laser. Lasers began to be used in the treatment of infertility between the 1980s and 1990; the first studies clearly indicate that human sperm motility as well as velocity can be improved by laser irradiation. After collection, the semen was taken immediately to the laboratory for sample preparation, physical and morphological analysis. Semen samples were irradiated by using laser light of (532nm) and power (54mW). The samples of semen used were of a concentration greater than 20 × 106/mL, and the ejaculate volume was greater than 5.0 mL. The gathered data suggests that primary photoacceptors are connected with oxygen metabolism and, in particular, with respiratory chains. It is important to recall that the activation by using diode laser was more effective than when we used ordinary technique, because the activation by laser light was more effective at activating the ATP production and, as a result, increased sperm motility, so laser light energized the sperm more than the other technique. We compared it with other studies. The aim of our study was to enhance infertility by enhancing sperm motility, and also to evaluate the role of laser activity in solving infertility problems.
