This article explains whether vitamin B12 deficiency leads to premature ejaculation with substantial scientific evidence. Before that, let us shed light on premature ejaculation.

What Is Premature Ejaculation?

Premature ejaculation, also called PE, is the condition where the ejaculation takes place within one to three minutes of sexual arousal. Men with premature ejaculation feel depressed and embarrassed due to the inability of satisfying their partners.

How Does Vitamin B12 Deficiency Cause Premature Ejaculation?

There is an indirect connection between Vitamin B12 and the development of premature ejaculation. 

According to the 2019 study, Vitamin B12 acts as the major component in the synthesis of serotonin which plays a vital role in ejaculation. 

To make it more clear, Vitamin B12 is one of the factors involved in the formation of S‐ adenosylmethionine, a chemical essential for the synthesis of serotonin. Serotonin is a key messenger hormone that helps in stabilizing your mood, emotions, and sleep by transmitting signals between brain nerve cells.

Hence, Vitamin B12 at a normal level leads to the production of serotonin which will delay your ejaculation and stabilize your sexual behavior.

What happens if there is a deficiency in Vitamin B12? The low level of Vitamin B12 disrupts serotonin synthesis, which in turn causes premature ejaculation. Hence, you require a long-term Vitamin B12 treatment to improve ejaculation time.

Is There Any Evidence To Support The Connection Between Vitamin B12 Deficiency And Premature Ejaculation?

Yes.

A 2019 study published in the Journal of Urological Surgery revealed a connection between premature ejaculation and Vitamin B12 deficiency.

Another 2017 study published in Andrologia journal also demonstrated that the presence of premature ejaculation was associated with a low level of Vitamin B12.

A 2018 study reported that patients with premature ejaculation had lower Vitamin B12 levels when compared with normal patients.

What Are The Foods Rich In Vitamin B12?

Vitamin B12 is naturally present in:

• Milk
• Egg
• Curd
• Chicken
• Liver
• Salmon
• Tuna
• Clams
• Oysters and mussels
• Fortified breakfast cereals

What Are The Other Treatment Options For Premature Ejaculation?

The common treatment options available for premature ejaculation include:

Priligy (Dapoxetine) – Priligy contains the active ingredient dapoxetine. It is a type of selective serotonin reuptake inhibitor (SSRI). It works by increasing the serotonin activity in the nervous system, thereby elevating the ejaculation time. Taking 30mg of Priligy (Dapoxetine) 30 minutes before sexual intercourse can treat premature ejaculation by absorbing quickly in one to three hours. 

Lidocaine spray - The application of this topical anesthetic spray to your penis works by reducing sensitivity in the skin tissue. As your sensation remains less during foreplay, you are less likely to ejaculate earlier. Thus, lidocaine spray treats premature ejaculation by significantly improving ejaculation time and sexual satisfaction. Lidocaine spray acts quickly within five minutes. 

Is There Any Adverse Interaction Between Viagra (Sildenafil) And Vitamin B12 Supplements?

No adverse interaction was reported between Viagra (Sildenafil) and vitamin B12. However, you should consult your doctor before taking Viagra with Vitamin B12.
