Does creatine cause premature ejaculation?

What is creatine?
Creatine is an amino acid found naturally in a body in the form of amino phosphate. Amino phosphate forms ATP (Adenosine triphosphate) which is responsible for providing energy to contract muscles. Thus, the function of creatinine is to provide energy to muscles and nerve cells. It forms 1% of the total blood volume.
There are different forms of creatine such as creatine monohydrate and creatine nitrate. Creatine is one of the most common supplements used by athletes.
Effect of creatine on sexual health
Creatine makes the body produce more energy. The body produces its own creatine using amino acids glycine, L- arginine, and methionine. It is mostly used as a supplement by athletes and bodybuilders for a better result.
As we have discussed above creatine produces energy in the body. According to the studies it is found that creatine may increase the testosterone (a male hormone) level in males.
Conclusion So, creatine may increase the level of testosterone but has no effect on premature ejaculation or any other sexual disorder.
