Abstract

Effect of laser on terminating early pregnancy in rabbits and mice showed that laser in combination with HPD could induce necrosis of blastocysts and complete
absorption. The anti-fertility efficiency of the combined treatment was more
effective than that of the He-Ne laser or the HPD treatment alone. The fluroescence spectrum of HPD determined by PNQ3 showed that its affinity to embryonic tissue was about 4 times greater than that to uterine tissue. These may underlie the mechanism of anti-early pregnancy of the laser.
