Can Mounjaro Cause Erectile Dysfunction? What You Need to Know

The Mounjaro Pen is a weight-loss tool designed to suppress appetite and help you feel full faster. Containing tirzepatide, Mounjaro mimics the GLP-1 and GIP hormones in the body usually released after eating to signal fullness. When used alongside healthy eating habits and lifestyle changes, Mounjaro has proven to be an effective weight-loss tool. While most people tolerate Mounjaro well, some have reported unexpected side effects, including issues related to sexual health, such as erectile dysfunction (ED).

 

What Is Erectile Dysfunction?

Erectile dysfunction is the inability to achieve or maintain an erection firm enough for sexual activity. It’s more common than many realise, affecting up to half of men over 40 to some degree, and can be caused by a wide range of physical and psychological factors, including:

• Blood flow problems
• Hormonal imbalances
• Stress and anxiety
• Certain medications
• Underlying health conditions such as diabetes or obesity
• Understanding the cause is key to finding the right treatment

 

Is There a Link Between Mounjaro and ED?

There’s no strong clinical evidence directly linking tirzepatide (Mounjaro) to erectile dysfunction. However, a small number of anecdotal reports online suggest that some men have experienced ED symptoms after starting GLP-1-based treatments. This may be due to a few reasons:

 

Blood Sugar Changes

For those with type 2 diabetes or insulin resistance, a sudden drop in blood sugar (especially if not well balanced) can occasionally impact sexual performance. Mounjaro is effective at improving glycaemic control, but if blood sugar dips too low, it could contribute to temporary symptoms like fatigue, dizziness, or even erectile issues.

 

Hormonal Adjustments

Significant weight loss, which is common with Mounjaro, can sometimes lead to temporary shifts in hormone levels, including testosterone. In the short term, this hormonal adjustment could potentially affect libido or sexual function though it typically stabilises with time and improved metabolic health.

 

Psychological Impact

Starting a new medication, especially one focused on weight or diabetes, can bring about stress or anxiety, which are well-known triggers of erectile dysfunction. In these cases, the cause is more psychological than physiological.

 

Long-Term Sexual Health

While beginning a GLP-1 treatment such as Mounjaro may cause temporary issues with sexual health, these should not last long. The long-term benefits from Mounjaro such as improved cardiovascular health, better blood sugar control, and weight loss all contribute to long-term improved sexual function.

Weight gain and obesity are large contributors to ED, and even moderate weight loss can improve sexual health particularly in relation to erectile dysfunction.
