A new study shows that a small group of microorganisms can influence sperm motility
You may have heard about the gut microbiome and its influence on a person's overall health and well-being. It turns out the same thing can happen with the seed microbiome.
According to researchers at the UCLA Department of Urology, semen microbiota may play a crucial role in influencing sperm parameters and improving male fertility. Taking into account recent studies highlighting the importance of the microbiome in overall human health, researchers examined the semen microbiome to understand its potential impact on male infertility. Research into the functions of these microorganisms in sperm could pave the way for the development of treatments aimed at correcting problems with sperm parameters.
Men with more Lactobacillus iners were more likely to have problems with sperm motility.
The study found that a particular microbe, Lactobacillus iners, can have a direct negative impact on male fertility. The researchers found that men with more of these microbes were more likely to have sperm motility problems.
Previous research has shown that the Lactobacillus iners may preferentially produce L-lactic acid, which could lead to a locally pro-inflammatory environment that could have a negative impact on sperm motility. The study authors point out that existing research suggests a link between this microbe and fertility, but the majority of the literature relates to the vaginal microbiome and female factors. This is the first study to show a negative link between the microbe and male fertility.
The researchers also found that three types of bacteria from the Pseudomonas group were present in patients with both normal and abnormal sperm concentrations. The microbes were calling Pseudomonas fluorescens And Pseudomonas stutzeri occurred more frequently in patients with abnormal sperm concentrations, while Pseudomonas putida occurred less frequently in samples with abnormal sperm concentrations.
However, the results suggest that not all members of the same closely related group may positively or negatively influence fertility in the same way. In other words, even closely related microbes may not always have the same direct connection to fertility.
“There is still a lot of research to be done regarding the microbiome and its connection to male infertility,” said Vadim Osadchiy, a resident in the UCLA Department of Urology and lead author of the study. “However, these results provide valuable insights that can lead us in the right direction for a deeper understanding of this relationship.” “Our research is consistent with findings from smaller studies and will pave the way for future, more comprehensive research to explore the complex relationship between the “To clarify the seed microbiome and fertility.”
