The Breadth of Viruses in Human Semen
Emerging Infectious Diseases
|October 20, 2017
Summary
Zika virus RNA can persist in semen after infection. A review found that 27 different viruses can be detected in human semen, highlighting the potential for sexual transmission of various viral infections.
Area of Science:
- Virology
- Infectious Diseases
- Public Health
Background:
- Zika virus ribonucleic acid (RNA) has been frequently detected in male semen following infection.
- Understanding viral persistence in genital fluids is crucial for disease transmission dynamics.
Purpose of the Study:
- To investigate the persistence of viruses in human semen.
- To identify the range of viruses that can be found in semen.
Main Methods:
- A literature search was conducted using PubMed to identify relevant articles.
- Articles reporting the detection of viruses in human semen were reviewed.
Main Results:
- Evidence was found for the presence of 27 distinct viruses in human semen.
- These viruses represent a broad spectrum of viral families.
Conclusions:
- Human semen can harbor a variety of viruses, indicating potential routes for sexual transmission.
- Further research is warranted to understand the implications of viral shedding in semen for public health.

11.9K
During ejaculation, males release around 2-5 milliliters of semen, which is a complex mixture of mature sperm and various fluids produced by accessory glands. The mature sperm cells measure approximately 60 micrometers in length and consist of a head, neck, midpiece, and tail. The head is flattened and tapered, measuring about 4 to 5 micrometers in length. It contains a nucleus with condensed chromosomes and an acrosome, a cap-like structure filled with enzymes essential for penetrating the...

Archaeal viruses play a crucial role in the ecosystems of extremophilic archaea, particularly those belonging to the phyla Euryarchaeota and Crenarchaeota. By shaping host evolution and facilitating gene transfer, these viruses influence microbial communities and contribute to genetic diversity in extreme environments. The archaea they infect thrive in acidic hot springs and hydrothermal vents characterized by high temperatures and low pH. Archaeal viruses exhibit remarkable structural...

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...
