The intricate relationship between our bodies and the trillions of microbes living in our guts is essential to our health. However, this partnership isn't without its challenges, as the metabolic processes of bacteria and our own cells can sometimes clash. A new study has uncovered a crucial mechanism that resolves one such conflict, ensuring male fertility in mice. Qing Shang et al. found that certain enzymes in the body are essential for detoxifying acetate, a byproduct of gut bacteria, to prevent it from reaching harmful levels. When these enzymes, ACSS1 and ACSS2, are absent, acetate builds up in the bloodstream, leading to metabolic acidosis. This condition disrupts spermatogenesis, the process of sperm production, resulting in male infertility. This study highlights an overlooked metabolic incompatibility between hosts and microbiota, which deepens our understanding of host-microbiota interactions and opens up new avenues for addressing fertility issues linked to metabolic dysfunctions.
