Understanding Prolactin: What It Does and Why It Matters

Prolactin is a hormone produced by the pituitary gland, sitting right at the base of your brain. You might mostly hear about it when talking about breastfeeding, since it helps mothers produce milk. But prolactin does a lot more than that, especially for men's health. If prolactin levels get out of balance, it can lead to some surprising symptoms that you wouldn't immediately link to a hormone issue.

So why should you care about prolactin? Well, when levels get too high, it can mess with your sexual function, mood, and overall energy. Men might notice problems like erectile dysfunction, low libido, or even unexplained fatigue. Sometimes, high prolactin can cause headaches or vision issues because the pituitary gland gets a bit swollen. If you're feeling off and can't figure out why, prolactin might be a hidden culprit worth checking.

Common Causes of Prolactin Imbalance

It's normal for prolactin to rise in certain situations like pregnancy, stress, or even after exercise. But persistent high levels could come from other reasons, such as medication side effects or pituitary tumors called prolactinomas. These tumors aren't usually cancerous, but they do produce excess prolactin that throws your body's balance out of whack.

Lower than normal prolactin is much less common but can happen due to pituitary damage or other rare conditions. Since prolactin influences other hormones, any imbalance can ripple through your body's systems and cause various symptoms.

What You Can Do If You Suspect Prolactin Issues

If you notice symptoms like sexual problems, unexplained headaches, or changes in your mood and energy levels, it’s a good idea to see a healthcare provider. They’ll likely order a simple blood test to measure your prolactin levels. Depending on the results, further tests such as MRI scans might be needed to check your pituitary gland.

Treatment usually depends on the cause. For prolactinomas, doctors often prescribe medication that can shrink the tumor and lower prolactin levels. If medications aren’t effective, surgery might be an option. If your prolactin is high because of medications you're already taking, your doctor might adjust those drugs.

Knowing what prolactin does and how it affects your body helps you keep track of your health better. It’s not talked about a lot in everyday health conversations, but it’s a piece of the puzzle that could explain symptoms you might have been struggling with for a while.
