- Two patients who lost 20 to 60 pounds on the diet saw a dramatic improvement in their sperm samples.
- This is supported by evidence that keto can promote sexual health, but other healthy eating plans, such as the Mediterranean or DASH diet, are also associated with improvement.

There is new evidence that high fat, low carb keto diets may have benefits for reproductive health.
In new case reports, two obese men lost their weight on a very low-calorie keto diet, according to research from the Universidade de São Paulo, Brazil, presented at the 2020 European and International Oberian Congress, both of sperm count And significant improvement in quality was observed. ,
In the first case, the patient lost about 60 pounds over a three-month dietary period, reducing his body fat percentage from 42% to 34%. Subsequently, based on the percentage of motile sperm in a test sample, the quality of their sperm improved almost 100%. His testosterone levels also more than doubled.
The second case report was of a patient who lost less weight, 20 pounds in three months, 26% to 21% body fat. His sperm quality also improved, but he saw even more significant gains in sperm count, testing more than 100 million sperm in the final sample, an increase of nearly 30%. Interestingly, his testosterone levels decreased slightly.
These results were based on a diet plan called Prococcal, a high-study commercial weight loss method introduced in Spain in 2004 that differs from traditional keto in that it is both low-carb (less than 50 grams), but also 800 Is limited to calories a day.
Two patients hardly have a large enough sample size to make broad conclusions about keto and sperm count. But existing evidence supports the notion that a low-carb diet may have benefits for sexual health, as increased fat consumption supports healthy sperm levels.
Previous research has also been linked to high levels of dietary fat for increased testosterone.
You may not need a strict diet to improve sexual health.
One caveat to these findings is that extremely restrictive diets can have side effects, especially in the long term, and especially that very low calorie diets should only be made with medical supervision.
It is not just the keto diet that is particularly associated with other measures of improved sperm count, quality, and fertility. Evidence of any type of healthy dietary change can promote sexual health.
For example, the Mediterranean diet is associated with an improvement in erectile dysfunction. In a 2004 study, a healthy diet and exercise program helped improve erectile dysfunction in obese men.
A 2019 study found that eating processed foods linked poor sperm count, while eating more fish and sperm count was associated with better sperm count, which is also related to sex drive and overall sexual function.
The DASH diet, which limits red meats and full-fat dairy in favor of fruits, vegetables, and whole grains, has also been linked to higher sperm count, according to research.
This suggests that the benefits may be related to any one dietary pattern, such as keto, and more about improving overall health that affects every area of the body.
Now there is evidence that junk foods such as pizza and chips can reduce your sperm count, but eating fish and veg can improve it.
According to a new Netflix documentary, a vegetarian diet may promote erections. Here is the reality.
