Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The ability of sperm to swim is important for normal fertility. Men with a genetic variation in the gene coding for Choline Dehydrogenase (CHDH) have decreased energy production by sperm, and their sperm do not swim normally. The metabolic product of this gene is a nutrient called betaine (found normally in the diet as a part of many foods such as spinach, beets and grain products). This study tests whether treatment with betaine is safe and whether it can normalize energy production in sperm of these men and restore normal swimming ability.
