Paternal Dietary Influences on Sperm Quality

Genetic inheritance plays a crucial role in transmitting health-related information from parents to offspring. While lifestyle and environmental factors are known to impact sperm quality and influence the biological information passed on, the underlying mechanisms remain unclear. Animal studies have suggested that small, non-coding ribonucleic acid (sncRNA) regulates the activation and deactivation of genes in the sperm genetic material.

A study published in the journal Nature investigated the effects of a short-term dietary change on sperm quality. Eight men were provided with olive oil, vitamin D and omega-3 fatty acids as part of their diet for six weeks, while a control group of nine men maintained their standard diets. The researchers observed that the dietary intervention altered multiple sncRNA signals carried by the sperm, particularly those related to fatty acid metabolism and gene expression. These findings contribute to the growing evidence suggesting that paternal health and nutrition during conception may play a role in the developing embryo and possibly the long-term health of the child
