2. Trichomoniasis

It is a sexually transmitted disease that affects the genital organs and causes flow of bad smell that can smell like rotten fish and pain with sexual intercourse. However, its actual frequency is unknown, since its treatment is so simple that most cases are not reported.  These infections are caused by a parasite of the group of protozoan parasites, called Trichomona vaginalis, known simply as trichomonas.

Semen with a high concentration of zinc usually neutralizes this parasite. For this reason, almost all infected males have no symptoms or discomfort; and male eliminates the trichomonas without need of a treatment. Consequently, the man usually does not realize that he is infected and, unknowingly, can transmit the infection to a healthy woman.

In men with low zinc levels, symptoms such as discharge in urine, burning during urination, or burning may occur immediately after urination. On very particular occasions, the parasite may advance to the internal organs and provoke prostatitis and inflammation of the testis ducts (epididymitis).


3. Trimethylaminuria

Approximately 1 in every 200 thousand people in the world present trimethylaminuria , reason why it is considered rare disease ; however, the fact that few are affected has caused many doctors to ignore it and even prevent its diagnosis by considering that the patient requires only a good kind of personal hygiene to overcome it.

This metabolic disorder can occur in both men and women and is characterized by an unpleasant body odor resembling rotten fish, whose origin is in trimethylamine (TMA). This compound is formed in the intestine by bacterial degradation of various diet products containing choline , a nutrient found in fish, eggs, liver and legumes. A man that has trimethylamine would smell fishy odor in their sweat, urine, semen and breath . The concentration of choline in normal semen is between 0.9 – 1.4 mg/ml higher than this can be an indication that you have  trimethylamine.

 It is recommended:

  • Avoid consumption of eggs, viscera, lean meats, peas, beans, spinach, cabbage, some vegetables (beans, for example), nuts and fast food products such as lasagne, hamburgers and pizza.
  • Suppress fish, especially salmon and cod, as well as octopus, squid and crab.
  • It is important to follow nutritional indications and to maintain medical surveillance, since a diet without a very restrictive choline can produce other disorders, such as growth retardation, bone alterations and renal dysfunction.
  • Use soap and body lotions with low pH (between 5.5 and 6.5) for daily hygiene.


4. Prostate infections

Smelly semen that smells like pus or fish may be a sign of prostate problems .

Only men have prostate gland and is a smooth surface gland that is part of the male reproductive system and is usually the size of a walnut, although this size may vary over time. In many men the size of the prostate can increase especially in the 40 or 50 years.

The prostate is located under the bladder and surrounds the urethral duct. With the help of hormones secretes a milky discharge that mixes with the spermatozoa during ejaculation. It is believed to produce approximately 10 percent of the seminal fluid.

The prostate can suffer different disorders, the most frequent being the increase in size, to become infected or to undergo a tumor process. Thus, the two main disorders are:

  1. Benign prostatic hyperplasia (BPH) .
  2. Prostatitis.

The causes of prostatitis are diverse and depend on the type of pathogen that has caused inflammation of the prostate. These may be of bacterial or non-bacterial origin.

Symptoms may differ between whether prostatitis is caused by a bacterial origin or by a non-bacterial origin. But both share the behaviors of:

  • Sensation of burning, stinging or itching when urinating (dysuria).
  • Poliaquiuria (frequent urination).
  • Blood in the urine.

Prostatitis can also cause fever and chills.

In chronic bacterial prostatitis there may also be other symptoms such as:

  • Discomfort in the testicles.
  • Painful ejaculation .
  • Sensation of pressure and / or pain in the pubic region and lower abdomen.
