Can Metformin cause erectile dysfunction?
Metformin used to treat Diabetes is not directly known to cause erectile dysfunction (ED).
However, In some men, Metformin may contribute to lower testosterone levels or affect blood circulation.
Thus, Affecting these crucial factors can influence sexual function and may indirectly lead to ED by Metformin.
But, for many, it may also actually improve ED by managing Diabetes, a major underlying cause of ED.
If you're taking Metformin and noticing changes in your sexual health, you're not alone.
In this blog, we’ll help you know how Metformin works, its potential impact on your erections, and whether it helps or hinders ED based on your overall health.
What is Metformin?
Metformin is a diabetic medication that helps to lower blood glucose levels.
It increases insulin sensitivity within the body, allowing its natural occurrence and its proper use in our body.
The administering of Metformin during treatment therapy efficiently controls blood sugar levels.
What are the Uses of Metformin?
Metformin is primarily used to manage type 2 diabetes by improving the body’s sensitivity to insulin and helping lower blood glucose levels without increasing insulin production.
Unlike some medications like Sulfonylureas, which can cause low blood sugar, Metformin has a lower risk of hypoglycemia and is often prescribed alone or with other drugs.
It’s also used off-label for gestational Diabetes and is being researched for potential anti-cancer (anti-oncogenic) benefits.
Diabetes and Erectile Dysfunction
Diabetes is a metabolic disorder that disrupts insulin production or function, leading to high blood sugar (Hyperglycemia).
Over time, this can damage the heart, nerves, eyes, and blood vessels.
One lesser-known complication of Diabetes is erectile dysfunction (ED), which is 3.5 times more common in diabetic men.
Over half of men with Diabetes experience ED due to a mix of physical, hormonal, and psychological factors.
Physically, high blood sugar can damage blood vessels and nerves that support erectile function.
It impairs nitric oxide production, which is crucial for relaxing penile muscles and allowing blood flow needed for a penile erection.
Other issues include:
- Endothelial damage due to Diabetes reduces the production of nitric oxide.
- Plaque buildup in penile arteries restricts blood flow in the body
- Peripheral neuropathy impairs sensation and muscle control, making it harder to maintain an erection.
Together, these complications from Diabetes increase the risk of ED and affect sexual performance. Know what are the possible side effects of Diabetes Mellitus. and Find out can ED caused by diabetes be Reversed.
Can Metformin cause erectile dysfunction(ED)?
Metformin is commonly used to increase insulin sensitivity in type 2 diabetic patients.
However, insulin isn't the only hormone Metformin affects the body.
During use of Metformin, it can inhibit a key enzyme that helps in testosterone synthesis.
As a result, it may reduce circulating testosterone.
Lower testosterone levels can affect sex drive and penile blood flow, and it may develop complications of Erectile dysfunction.
But other diabetic drugs, like Sulfonylureas, which are not commonly prescribed, are not found to have the same effects on testosterone.

How does Metformin help erectile dysfunction?
In contrast with the information given above, some studies have also found Metformin helpful for Ed in diabetic patients.
Metformin can alleviate erectile dysfunction by helping diabetic patients.
Metformin improves insulin sensitivity and helps reduce insulin levels by properly using it.
As a result, it relieves Hyperglycemia, which can stop further damage to the blood vessels and nerve cells in the penile tissue.
Treatment with Metformin can help with erectile dysfunction by Increasing the blood flow to the penis by protecting the endothelium-dependent vasodilation.
Improving sympathetic nerve activity regulation improves erectile dysfunction in diabetic patients.
What Does Research Say About Metformin and Erectile Dysfunction?
Research offers mixed findings on Metformin’s effect on ED.
A 2014 clinical trial in The Journal of Sexual Medicine found it improved erectile function in insulin-resistant men by boosting nitric oxide activity.
Another study in Diabetes Care showed it may raise testosterone in obese men, supporting sexual health.
However, some observational studies report reduced libido or testosterone, particularly with long-term use of Metformin.
These effects may stem from poor blood sugar control or other health issues.
Compared to other antidiabetic drugs like Sulfonylureas or insulin, Metformin poses a lower risk for ED.
These alternatives are more likely to impact sexual function due to weight gain, hypoglycemia, and hormone disruptions.
Is Metformin Safe for Treating Erectile Dysfunction?
Metformin is generally safe and manages Diabetes by lowering blood sugar and increasing insulin sensitivity.
It can indirectly help prevent ED caused by Hyperglycemia.
However, it’s not recommended to treat EDs that are unrelated to blood flow or nerve damage.
Some studies suggest Metformin may reduce testosterone levels, which could negatively affect sexual function.
For diabetic patients with ED medications like Viagra, Cialis, or Levitra are better options.
A healthy lifestyle is also crucial.
If ED worsens while taking Metformin, consult a doctor to explore alternative treatments.
Final Lines:
Metformin is widely used to manage type 2 diabetes, but its effects on erectile dysfunction (ED) are mixed.
Some studies link it to lower testosterone, while others show it improves insulin sensitivity and reduces blood vessel damage, which may help prevent ED.
Patients experiencing worsening ED while on Metformin should consult a doctor to explore alternative treatments or combination therapies.
A healthy lifestyle and well-tolerated ED medications can help manage Diabetes and ED effectively.
Always seek medical guidance for the best results.

In a clinical study, researchers observed that men with Insulin-resistant had significant improvement in erectile function when Metformin was added to Sildenafil(Viagra). The use of Metformin can increase the activity of Sildenafil, and one must consult a doctor before using them together.
Cialis is generally found to be a safe drug for erectile dysfunction as it does not alter blood sugar levels in diabetic people. Cialis containing Tadalafil can also be used by people who are taking insulin.
Metformin can improve Ed by managing some side effects of Diabetes that can lead to Ed. It reduces the amount of blood glucose by enhancing the body's response to the sugar-regulating hormone(Insulin).
