Have you ever thought about using male enhancement pills? They can be bought online, through social media, or in some herbal medicine shops. But do male enhancement pills really work, and are they the best option for you?

What are male enhancement pills?
‘Male enhancement pills’ refers to a range of herbal products that are marketed as being able to improve sexual performance in different ways. Depending on the product, they might claim to do things like:
- making your erections harder
- treating erectile dysfunction
- increasing the size of your penis
- helping you last longer in bed
- boosting your sex drive (‘libido’)
Male enhancement pills are sold in shops and online as natural remedies for improving sexual performance. They’re usually made from plants and they often include a number of herbal supplements mixed together.
Some examples of male sex enhancement pills include:
- VigRX Plus
- panax ginseng
- DHEA
- yohimbe
- ginkgo
- horny goat weed (also known as ‘epimedium’)
Although male sexual enhancement pills can seem like an attractive option, it’s important to think twice before using them. This is because they aren’t proven to work in the same way real medications do, and they don’t have to go through the same amount of testing.
Male enhancement pills aren’t regulated in the same way as normal medications, so it’s harder to know how trustworthy, safe, and effective they are. They might not do anything to help with sexual performance and they definitely won’t improve your penis size, but they still come with some health risks.
Do ‘male enhancement’ pills really work?
Male enhancement’ pills are not proven to improve sexual performance in the same way real medications are. Some of them may work, but there’s simply not enough evidence to say for sure.
This is because they are not licensed medications. Male enhancement pills don’t have to undergo the same rigorous, clinical trials as real pharmaceutical drugs to prove they’re effective. In the end, you might end up spending your money on pills that have no actual benefits.
At present, relatively few studies have been done into the effectiveness of male sex enhancement pills. Studies that have been done tend to be small and inconclusive. You might have heard about people who have had positive experiences after taking these pills. However, this could be explained by the ‘placebo effect’. This is when you might see some improvement in your sexual performance because you believe you’re getting treatment.
Can male enhancement pills improve my penis size?
No, there is no way a pill can increase the size of your penis – this is impossible. Any product that claims to do this should not be trusted.
If you can’t reach your maximum erection size because of erectile dysfunction, then medical treatment could help. Real, licensed erectile dysfunction treatments like Viagra (sildenafil), Cialis, tadalafil, Spedra, or Levitra work by increasing blood flow to your penis. This could make it look larger when erect. However, it won’t actually be any bigger than its natural size.
The only way to make the penis physically larger is to get penis enlargement surgery. There are 2 main types of penis enlargement surgery:
- release of the suspensory ligament – to make the penis longer
- autologous fat injection – to make the penis thicker
Penis enlargement surgeries only change the look of a penis. They won’t improve sexual performance. There are also some risks involved in penis enlargement surgeries and some of them could negatively affect sexual performance:
- infection
- scarring
- penis shortening
- deformity of the penis
Reflecting on how you feel about your penis size
It’s understandable that you might consider using male enhancement pills to increase the size of your penis. There are many messages in the media, online, and in general culture about the supposed importance of penis size. However, these should be treated with some scepticism.
A clinical study has found that 13.12cm (5.17 inches) is a realistic average penis size for a full-grown adult, measured during a full-length erection. The study showed that, for many men, there’s a big difference between what they believe the average penis size is, and the reality.
What are the best male enhancement pills out there?
Since no male enhancement pills are proven to work, there’s no ‘best one’ to try. Though, there are some that are safer than others. If you do still wish to try male enhancement pills, make sure that you buy them from a reputable seller. Look for the Traditional Herbal Registration logo to make sure the product you’re buying is properly regulated.
There is a worrying trend of people selling unregulated or counterfeit male enhancement pills over the counter in some shops, online, or in places like pubs. It’s important to be wary of buying from unregulated vendors. These sellers may not know what’s inside the pills. They’re most likely to have no effect which means you could waste your money, or in the worst case scenario, they could cause serious side effects, or illness.
If you want to improve a specific condition like erectile dysfunction, licensed medications are a much better option. You can get erectile dysfunction treatment over the counter in a pharmacy without seeing a GP first. You can also order online without an existing prescription or any face-to-face appointments:

Can male enhancement pills give you side effects?
Yes, most male enhancement pills are very likely to have side effects. However, because these products don’t have to go through the same level of scrutiny and clinical trials as real drugs, much less is known about their side effects or how common they are.
Before a pharmaceutical company can sell a new drug, it must do years of testing with thousands of people to find out what side effects the medication might have, while testing its effectiveness. This is why we know, for example, that between 1 in 10 to 1 in 100 people who take sildenafil experience indigestion.
By contrast, we know much less about male enhancement pills’ side effects, because much less rigorous research has been done on them.
Many herbal products have been found to contain amounts of active medication ingredients that aren’t properly disclosed by their manufacturers. While this sounds like it might mean they could have some actual medical effect, they will be in amounts and combinations that could be unsafe.
When you get checked for real medications, the doctor or pharmacist can make sure there aren’t serious health risks for you. If you take herbal products that contain trace amounts of medication then you could be putting yourself at risk.
Are natural male enhancement pills safe?
No. Some companies that produce male enhancement pills emphasise the fact that their products are made from ‘natural’ herbal products. However, just because something’s ‘natural’, this doesn’t necessarily mean it’s good for you or safe.
Many plants, such as hemlock or deadly nightshade are ‘natural’, but are also extremely toxic. This isn’t to say that all herbal remedies are ineffective. But it’s important to consult with a fully trained medical professional before consuming a ‘natural’ product.
More effective treatments are available
There are many companies claiming that they sell the best male enhancement pills. While some users may have had positive experiences with these products, there’s no guarantee they’ll work for you, and you may experience serious side effects.
The good news is that there are many, highly-effective ways of treating male sexual performance issues:
Communication with your sexual partner
Many male sexual performance concerns can be resolved through open, honest communication with your partner. Whether you’re worried about your penis size, erectile dysfunction, or premature ejaculation, talking through any concerns with your partner can help you address them and improve your sex life.
Talking therapies
Speaking with a counsellor or sexual therapist can also be really helpful – especially if the cause of your sexual problems has a psychological root.
Licensed medications
There are several kinds of tried and tested medications that are proven to help with both getting an erection and addressing premature ejaculation.
At ZAVA, we deliver male sexual performance medication to your door, quickly, discreetly, and affordably. Learn more about erectile dysfunction and premature ejaculation treatment that actually works.
