Borax and testicular pain

As a male, I have experienced testicular pain after having used borax (1/8 teaspoon per day) for about two months. Borax gave me better mental clarity, probably because of the killing of fungus.

Honestly, I am ready to sacrifice my fertility in return for my sanity, after being affected by severe mental confusion for several years. I am just curious if borax has any real effect on the male reproductive system? All studies I find on the web used animals as test subjects. Probably there is no study on humans yet, haha...
