Key takeaways:
Glucagon-like peptide-1 (GLP-1) receptor agonists are a class of medications used to help treat diabetes and obesity. They include medications like Ozempic and Wegovy.
Some people taking semaglutide report symptoms of erectile dysfunction (ED).
There may be a higher risk of ED if you’re taking semaglutide for weight loss. But semaglutide may actually improve ED if you have diabetes.
Save on related medications
More people are taking semaglutide — either as Ozempic or Wegovy — for diabetes and obesity. Like any medication, semaglutide can cause side effects. Most of these side effects involve the gut. However, some people have reported symptoms of erectile dysfunction (ED) while taking semaglutide.
ED is a medical condition that causes trouble getting or keeping an erection. Certain medications can lead to ED. But is semaglutide one of those medications? The answer may surprise you.
Does semaglutide cause erectile dysfunction?
Experts are still investigating how medications like Ozempic and Wegovy affect the hypothalamic-pituitary-gonadal (HPG) axis, the system of the body that controls reproductive and sexual function.
Search and compare options
There’s some evidence that semaglutide can increase the risk of ED in people without diabetes. In a recent study, researchers found that people without diabetes who took semaglutide for weight loss had a higher chance of developing ED. But the overall rate of ED in this group was still very low — just 1.5%.
Can semaglutide ever help with erectile dysfunction?
Yes, semaglutide may actually improve symptoms of ED. There’s evidence that glucagon-like peptide-1 (GLP-1) receptor agonists may improve ED in people with diabetes. One small study found that adding liraglutide (another GLP-1 medication) to treatment with testosterone and metformin improved ED in people with diabetes.
Another study found similar results. In this study, people with diabetes and ED received both metformin and a GLP-1 receptor agonist. This group had improvement in their ED symptoms.
Researchers think there are a few ways GLP-1 receptor agonists may help with ED, including:
Better smooth muscle function
Improved blood flow
Less damage to the testicles
Can you take Viagra and Ozempic together?
Yes, most people can take Viagra (sildenafil) and Ozempic together. There are no known interactions between these two medications.
Can you take Cialis and Ozempic together?
Yes, most people can take Cialis (tadalafil) and Ozempic together. There are no known interactions between these two medications.
What to do if you experience erectile dysfunction?
If you notice ED after starting Ozempic or another GLP-1 medication, there are several steps you can take:
Talk with a healthcare professional. Don’t stop semaglutide on your own. Your prescriber can figure out whether your ED is related to the medication, an underlying condition, or something else.
Review other possible causes. ED is often linked to diabetes, heart disease, low testosterone, stress, sleep problems, or other medications.
Give your body time to adjust. Some side effects may improve as your body adapts to semaglutide or as your weight loss stabilizes.
Ask about treatment options. Many ED treatments are safe for most people to take with Ozempic and may help manage symptoms.
Focus on overall health. Managing blood sugar, weight, and getting enough exercise and sleep can all support sexual function.
Frequently asked questions
Yes, semaglutide may increase testosterone levels. This may be a result of weight loss while on semaglutide. Or semaglutide may have a direct effect on the testicles.
Yes, most people can take Wegovy with Viagra or Cialis.
Yes. ED caused by diabetes can be improved or even reversed when your blood sugar stays within a normal range. Lowering blood sugar can restore the blood flow and nerve function that you need for erections. But keep in mind that if your diabetes has caused permanent nerve or blood vessel damage, you may notice only partial improvement in your ED.

The bottom line
A small number of people without diabetes who use semaglutide for weight loss may experience erectile dysfunction. But for people who have Type 2 diabetes, GLP-1 receptor agonists like Ozempic or Wegovy may actually improve symptoms of erectile dysfunction. Researchers need to do more work to understand the connection between semaglutide and erectile dysfunction.
