Is that Penis Odor Due to Trimethylaminuria? It’s an unfortunate fact that penis odor can be a big issue for many men, and one that can be incredibly off-putting to a potential partner. There can be many reasons for a rank penis odor, even in a man who is careful about his penis health and hygiene. One of the more obscure causes may be trimethylaminuria, a condition sometimes known as fish odor syndrome. If that sounds familiar, read on. What is trimethylaminuria? Trimethylaminuria is a relatively recent condition, first diagnosed in the 1970s. It is a genetic disorder, so it’s something that a person is born with, not something that a person catches from someone else. This disorder affects the body’s ability to process something called trimethylamine, an organic compound that is associated with decomposition of plants and animals. In the human body, it is often found in foods that contain choline, a water-soluble nutrient. These foods cover a wide range of dietary sources, including cauliflower, spinach, beef liver, broccoli, chicken, soybeans, seafood, eggs, grapefruit and tofu. When a person has trimethylaminuria, the trimethylamine isn’t broken down the way it’s supposed to be. An excess of it therefore stays in the body, creating a very strong smell. That stink can come out through sweat, urine and semen – all of which can contribute to a fishy penis smell. Is it dangerous? Trimethylaminuria is not generally dangerous, but it can be annoying – and embarrassing when the odor it produces is extreme. For a man who already has a strong case of penis odor, it can be especially embarrassing. Even though a man may be very hygienic and wash thoroughly and frequently, if he has trimethylaminuria, it may still break through and cause a rankness that is unpleasant. Fortunately, trimethylaminuria is rare – but that is small comfort to those who must deal with its effects. Treatment www.man1health.com
