Male enhancement pills can be bought over the counter or on the internet. They are usually herbal in nature (the are made using plant extracts). Usually these male enhancement products make claims on the packaging about enlarged penis size and enhancing sexual performance. For example a male enhancement pill may contain substances that increase blood flow in the body and may therefore claim to increase blood flow specifically to the penis area to improve sexual function however there isn’t always enough evidence to prove that they actually work. That being said, there is some evidence to suggest some herbal products may improve sexual function. For example maca is a Peruvian herb known as being 'adaptogenic', meaning it helps to keep the bodies systems balanced, including hormone levels. Other popular herbal remedies include saffron, muesli, and mondia whitei with some evidence suggesting they can play a role in enhancing sexual arousal and performance.
