American scientists have found through research that regular consumption of foods such as pumpkin leaves and seeds, white onions, ginger and tomatoes, along with proper physical exercise and maintaining a healthy weight, not smoking and not drinking excessively, will help men improve their sperm quality. There are many causes of temporary poor sperm quality, including STDs, alcohol abuse, smoking, overload, hot environments, tight underwear, insomnia, work and emotional stress. It is entirely possible for patients to improve sperm quality through a healthy lifestyle. Nutritionists point out that many plants and healthy foods can help increase sperm count and improve sperm quality. Fresh dark green juice extracted from fenugreek leaves diluted with the same amount of fresh milk, one cup a day can be a great tonic and help men increase their sex drive and improve sperm quality. Researchers also say that by supplementing with zinc not only can boost testosterone production, but also increase sperm count. Therefore, it is useful to eat pumpkin seeds because they are rich in zinc.
