In an uncontrolled trial in 100 men with infertility, a combination supplement containing 800 mg alpha-lipoic acid, 100 mg betaine, 400 mcg folic acid, 1,000 mg myo-inositol, 2.6 mg B12, 1.7 mg riboflavin, and 1.9 mg B6 was tested and reported to improve sperm concentration, motility, and morphology
The most common is injecting too quickly, which creates a pocket of medication that absorbs slowly and forms a temporary nodule
