In a new study reviewing existing literature, researchers have found that more than 2 dozen viruses have been detected in human semen. Since researchers found that the Zika virus was present in semen and can be passed through sex, health officials have warned of sexual transmission of the virus. Now in a recently published paper, researchers found evidence that more than two dozen additional viruses can be found in human semen, though many questions remain on how this may impact public health. In , a study in the journal Emerging Infectious Diseases , published by the Centers for Disease Control and Prevention CDC , detailed preliminary findings from an outbreak in French Polynesia on the presence of Zika virus in semen, suggesting that the flavivirus could be sexually transmitted. Although the Zika virus has primarily been thought of as a mosquito-borne disease spread by the Aedes aegypti mosquito, health officials investigated other transmission pathways of the virus in the wake of the Zika virus outbreak in South America and the subsequent rise in the number of infants born with microcephaly. In , prompted by a case of sexual transmission of the virus reported in Texas, the CDC released findings confirming that Zika can be transmitted from a male to his partner via semen.

Dozens of Viruses Can Be Detected in Human Semen

When scientists discovered that the Zika virus can survive in semen for up to 6 months, people exposed to the disease—especially those hoping to have children—were horrified. Now, a new meta-analysis has found that 26 other viruses can also live in human semen and go on to infect the bloodstream. After reviewing more than scientific publications, the authors also found evidence that at least 11 viruses can live in the testes, including those that cause influenza, dengue, and severe acute respiratory syndrome. These viruses could potentially be found in semen, too, the authors say. Though not all 27 viruses are capable of person-to-person transmission, they can have other serious consequences, like reducing fertility or increasing the risk of acquiring a sexually transmitted disease. Some of these viruses can even cause mutations in the DNA of sperm, which could then fertilize an egg and pass along the virus-induced mutations to future generations. But the authors warn that far more research is needed to understand how and whether the viruses can be sexually transmitted and exactly which viruses remain viable in semen, for how long, and at what concentrations.

The Breadth of Viruses in Human Semen

There are other ways of describing how germs are spread that are commonly used. Germs can be spread through sexual contact , which is usually through semen and vaginal secretions body fluids , but can also occur through contact with mucus membranes. Germs can spread through food or water.

These include viruses that have been at the center of recent epidemics, like Ebola and Marburg, as well as viruses like mumps and adenovirus, which can cause a version of the common cold. The viruses appear to take advantage of one of the body's key protective mechanisms, known as immune privilege. Certain parts of the body, like the eyes, are essentially no-fly zones for the immune system's defense armies. They are shielded from inflammation to protect more critical functions like vision.
