Abstract
The overall objective of this paper is to develop a more sensitive and less costly technique of laser irradiation of spermatozoa at certain wavelengths and exposure times suitable for improvement of buffalo semen quality. A 532 nm continuous wave (CW) DPSS laser light has been used to irradiate buffalo semen for different time intervals. Three semen pools from three different bulls (Bubalus bubalis) were used in the experiment, each pool was divided into six groups : control (not irradiated), and the other five were exposed to laser light for 1, 2, 3, 4 and 5 minutes with fluencies of 0.076, 0.15, 0.23, 0.31, and 0.38 Joule/cm2 respectively at an output power 1mW. The results show that the semen quality parameters increase under the effect of laser irradiation. Maximum improvement in the semen quality has been reached after 4 minutes of exposure. Such results indicate the possibility of adopting laser irradiation as an easy and straightforward technique for in situ improvement of the semen quality to optimize the artificial insemination conditions.
