Insights
Sexually transmitted diseases (STDs) are linked to impaired sperm motility in men with Human Immunodeficiency Virus (HIV). Leucocytospermia, or white blood cells in semen, may indicate HIV infection.
Area of Science:
- Reproductive Health
- Infectious Diseases
- Andrology
Background:
- Sexually transmitted diseases (STDs) are a global health concern.
- Human Immunodeficiency Virus (HIV) significantly impacts male reproductive health.
- The interplay between STDs, HIV, and semen quality requires further investigation.
Purpose of the Study:
- To investigate the association between STDs and HIV in men.
- To determine the effects of STDs and HIV on semen characteristics and seminal leucocytes.
- To explore leucocytospermia as a potential indicator of HIV infection.
Main Methods:
- Cross-sectional study of 83 fertile/infertile men.
- Analysis of HIV antibodies in semen, andrological parameters, and seminal leucocytes.
- Comparison of semen characteristics between HIV-positive (HIV+) and HIV-negative (HIV-) men with and without STD history.
Main Results:
- HIV+ men exhibited significantly lower sperm motility (p < 0.02).
- Leucocytospermia was prevalent in HIV+ men, particularly those with a history of STD (p < 0.001), and even in HIV+ men without STD history (p < 0.05).
- Non-ulcerative STDs were identified as a risk factor for HIV infection.
Conclusions:
- Impaired sperm motility in HIV+ men may be linked to activated seminal leucocytes and oxidative stress.
- Leucocytospermia appears to be a reliable indicator of HIV+ status.
- Understanding the relationship between STDs and HIV is crucial for male reproductive health management.
Abstract:
A cross-sectional study was conducted on 83 fertile/infertile men to investigate the association between STDs and HIV and their effects on semen characteristics and seminal leucocytes. HIV antibodies in semen, andrological parameters and seminal leucocytes were analyzed. Of the 83 subjects, 36 were HIV+ and 47 were HIV- . Only 9 out of 36 HIV+ men and 25 out of 47 HIV- men had no history of STD. The most common type of STD was gonorrhea (65%) and 60% of those who had gonorrhea were HIV+ . HIV+ men had low sperm motility (p < 0.02). HIV+ men with a history of STD had leucocytospermia compared to HIV- men irrespective of history of STD (p < 0.001). Leucocytospermia was prevalent in HIV+ men even with no history of STD (p < 0.05). Non-ulcerative STDs was a risk factor for HIV infection. There was a significant association between HIV- and no history of STD. Impaired sperm motility in HIV+ men may be mediated by activated seminal leucocytes, which could induce oxidative stress on sperm. Leucocytospermia may be a reliable indicator of HIV+ .
