Whether you use raw or cooked onions, these root vegetables pack some powerful nutrients and other health benefits.
Historically used to treat ailments like headaches, mouth sores and even heart disease, the medicinal qualities of onions have been known for thousands of years.
Onions are nutrient-dense, meaning they’re low in calories but high in vitamins and minerals. A medium onion, for example, has less than 50 calories but contains a considerable amount of vitamins, minerals and fiber.
This vegetable is high in vitamin C, which is important for supporting immune health, collagen production and iron absorption. The antioxidant properties of vitamin C can also protect cells against damage from free radicals.
There’s also a high amount of B vitamins — particularly vitamin B6 and folate — which help with metabolism, nerve function and the production of red blood cells.
The antioxidant properties of onions may even support heart health, as they fight inflammation and reduce cholesterol levels — all of which may lower heart disease risk.
Antioxidants inhibit oxidation, a process that contributes to diseases like cancer, diabetes and heart disease.
What’s more, the anti-inflammatory properties of onions may reduce blood pressure and prevent blood clots.
Quercetin, an antioxidant highly concentrated in onions, has potent anti-inflammatory properties that may help decrease heart disease risk factors like high blood pressure.
Onions even have antibacterial properties, with the antioxidant properties of quercetin being able to fight off harmful bacteria.
But what are the benefits of onions sexually? Can they help with erectile dysfunction (ED) or improve sexual health in other ways? Keep reading to learn about onion benefits for men.
Now you know about the many health benefits of common onions. So, what are the benefits of onions sexually?
Eating onions might boost your testosterone levels, the primary sex hormone responsible for sperm production, as well as sexual characteristics during puberty (muscle strength, deepening voice and facial hair, to name a few).
A review of studies found that consuming onion extracts or onion juice increased testosterone production. However, 75 percent of these studies were conducted on male rats.
One of the studies found that rats that consumed onion juice had increased testosterone production.
This study also discovered that rats that were experiencing sexual dysfunction from paroxetine (a common antidepressant used to treat depression) also had increased production of testosterone from the consumption of onions.
Eating onions may also help with erectile dysfunction, a common condition in men.
The gist of how erections work is that chemical messages are sent from the brain to relax muscles in the penis, which then allows blood to flow to the base of the penis.
Blood flow to erectile tissue allows the penis to become firmer and harder, creating an erection. Erectile dysfunction medications, such as sildenafil (Viagra®), can help stimulate blood flow back to the penis.
Onions’ anti-inflammatory properties and certain B vitamins can help produce red blood cells, decrease blood clots and increase blood flow — which may help with ED. A study on male rats also found that red onion juice had a positive effect on erectile dysfunction.

Considering onions' reputation for giving people bad breath, it might be surprising to learn that this food is viewed as an aphrodisiac — a food that stimulates sexual desire.
Eating onions has been shown to increase testosterone production, mostly in male rats from older studies. This increase may affect sexual desire in men, but more research needs to be done.
Many studies have found onions to have a few sexual benefits for men. Namely, possible increased testosterone production and sexual desire, as well as reduced erectile dysfunction.
However, these studies were older and mostly conducted on rats. So, to find out the true benefits of onions sexually, more research is needed.
