Highlights
- With the new era of space travel, experts are concerned with the sexual health of astronauts.
- Scientists are trying to understand the potential erectile dysfunction causes for men in space.
- Recent animal study found links between simulated cosmic radiation, microgravity, and ED.
- Targeted treatment with antioxidants may help astronauts suffering from ED after their missions.
- The discovery may have implications for all men with erectile dysfunction.
Erectile dysfunction causes a lot of stress for men and their partners. An unusual, NASA-backed study revealed that another type of stress, called oxidative stress, may lead to increased risk of ED for astronauts returning from space missions.
Surprisingly, these cosmic considerations may have a real impact on the treatment of erection problems here on Earth.
New Era of Space Exploration and Astronaut Health
When the movie “Martian” premiered in cinemas in 2015, the idea of long-distance space travel seemed like science-fiction. Today, NASA is working on technologies which could send humans to Mars as early as in the 2030s.
In addition, the new era of moon exploration has begun. In the next few years, astronauts will set foot on the moon once again, this time staying for a few days at a time.
As new space frontiers open, researchers are trying to predict the impact of exposure to cosmic radiation on human health. And that includes sexual function.
Believe it or not, there’s a field of study called space sexology! Researchers from medical and psychological fields are trying to predict the implications of longer, distant space missions on people’s ability to reproduce and have sex.
Study Explores Links Between Space Travel and ED
NASA has been funding research into potential health complications for space mission crew members. One paper, published in the Journal of the Federation of American Societies for Experimental Biology, addressed some never-before asked questions.
Scientists have investigated a possible link between space travel and erectile dysfunction in male astronauts. For practical reasons, they conducted their experiments on male rats. As strange as it may sound, rodents have been used in biomedical research for years, due to their physiological, anatomical, and genetic similarity to humans.
The animals were placed in space-like conditions at the NASA laboratory. First, they were exposed to simulated cosmic radiation and microgravity. Next, they underwent a 12- to 13-month period of recovery. Finally, their tissue samples were examined.
The study revealed that even in those simulated space conditions, animal tissues showed higher levels of oxidative stress. Oxidative stress is a known factor in aging and development of certain diseases. In addition, it may impact arteries that play a role in erectile function.
Scientists concluded that their discovery exposed a potential health risk in the context of cosmic travel.
Chance for New Erectile Dysfunction Treatments
The topic of erectile dysfunction causes in astronauts may seem remote from everyday reality, but it’s not.
Researchers who studied the effects of simulated space travel on ED believe that treatments with antioxidants may mitigate the negative effects of oxidative stress on erectile function. And it’s not just good news for men in space suits.
Antioxidants are molecules our bodies produce to fight free radicals. If you have too many free radicals flowing in your system, you’re at risk of illness.
Antioxidants are available in the body, but they can also be found in certain foods. Vitamins C and E are known sources.
Researchers have conducted many studies on the effects of antioxidants. The result of the NASA-backed study provides another argument in favor of further research on the topic.
The Link Between Antioxidants and ED
To get a better understanding of the role of antioxidants in sexual function, think of them as superheroes roaming the city. Those superheroes can spot and neutralize villains causing damage to the main traffic arteries of the city (and to your blood flow). The villains are called free radicals.
If your body is unable to send enough antioxidants to fight the free radicals, it creates oxidative stress. That in turn plays a big role in the dysfunction of blood vessels and cells which form the linings of those vessels. Possible result? Poor blood flow to the penis — and erectile dysfunction.
Should You Add Antioxidants to Your Anti-ED Diet?
If antioxidants are such a promising option for space travelers, should regular men be interested, too? The current answer is, maybe. But consuming antioxidant-rich foods won’t harm you, so you have nothing to lose if you give it a try.
Studies indicate that delivering extra antioxidants to your body may improve blood flow and reduce the risk of ED. Many of those results are, however, insufficient for a definitive verdict.
According to a systematic review on the effects of antioxidant supplementation on erectile dysfunction, your best bet is to combine an antioxidant-rich diet with a PDE-5 inhibitor medication for ED.
If you’d like to give antioxidants a try, talk to your doctor or a certified nutritionist, who can suggest the best foods and supplements.
Getting nutrients from food sources is always your best bet, so here are examples of antioxidant-rich foods that will give you the benefits of these nutritional powerhouses naturally:
- Broccoli
- Leafy greens
- Beets
- Shrimps
- Lentils
Lessons From the Exploration of Space ED
The study on the effects of microgravity and cosmic radiation on erectile function exposed the link between sexual health and oxidative stress.
While the background of this research seems exotic, similar studies on men living here on Earth have also shown the connection between ED and oxidative stress.
And the promising solution is similar for both the Earth dwellers and space travelers. A diet rich in antioxidants may improve cardiovascular health and reduce the risk of erectile problems.
We need more research to confirm and understand this issue, but switching to a healthier diet can only do you good. So, go ahead, order that side of broccoli with your next lunch!
