Like was done in the hair loss industry, why not give a guy the opportunity to make a simple device on their own, inexpensively, to test for themselves? Well, here it is.
The study uses 808nm 150mw lasers which are infrared. I have provided links to those lasers if you wish to try them. However, I suggest that you use 635nm 5mw lasers which are the same as used in most LLLT products today and are known to have the same stimulative effects.
For a total expense of about $54 USD and a bit of your time, its an inexpensive attempt at a solution based on clinical science. I know many people who have tried this type of device, using the hair growth lasers as a basis, with results.
So lets get started!
Step 1: Parts You Will Need
1) An athletic cup which can be purchased at any sporting goods department for about $8. The pre-drilled air holes are very useful in the construction.
2) Three 8x13mm 635nm 5mw lasers which can be found at http://www.aixiz.com/store/product_info.php/cPath/23_34/products_id/87
3) One 3.2VDC power supply which can be found at http://www.aixiz.com/store/product_info.php/cPath/51/products_id/219
Step 2: Prepare the Lasers
Step 3: Mount the Lasers
Note that I am only using three lasers in this model, there is nothing that says you cannot use more, I am just being lazy and using the three air holes that already exist.
Secure the lasers into the air holes but don't set them to tight, you will need to adjust them later.
Step 4: Wire the Lasers
Step 5: Connect to the Power Supply
Step 6: Test and Align
Gently twist the lasers until all three are running parallel to each other from the top to the bottom of the device. It will be obvious, trust me on this.
Step 7: Finished!
