The last 50 years has seen a rapid decline in male reproductive health. Decreased sperm counts, increased rates of testicular cancer and a range of malformations in male genitalia have been reported worldwide. Age also plays a factor in the production of sperm, and as we age chances of conception drop. Other factors such as lifestyle, smoking, obesity and congenital malformations also play a part, and overall, 40% of infertility cases are caused by male reproductive issues, 40% by female reproductive issues, and one-third by a combined male / female reproductive issue or by unknown factors.
How can Low Level Laser Therapy help?
The authors of the studies provided at the end of this article, have concluded that Low Level Laser Therapy (LLLT) or Photobiomodulation can assist with sperm motility. The studies were carried out on many and varied species, such as bulls, turkeys, stallions, sea urchins and humans, with both fresh and frozen semen. However, the overall consensus is that the motility of the sperm increased, the number of sperm increased and the number of abnormal spermatozoa decreased. It was also noted that there was no DNA damage and the treatment was completely safe.
What the Low Level Laser Therapy does, is increase blood flow in the area being treated. Because laser works at a cellular level, on the mitochondria (the powerhouse) of the cell, the cell will be taken out of a stressed state, (oxidate stress) and mitochondrial activity is increased. The capacity of cold laser to improve ATP (Adenosine Triphosphate) production has a positive effect on the production of motile sperm.
