El MundoIndependent🔒Center22 hr. agoA study conducted in Spain has revealed significant differences in sperm quality among men from different regions, with Asturians showing nearly double the sperm quality compared to Madrid residents. The research analyzed data from nearly 400 men across four Spanish regions—north, south, southeast, and center—who underwent fertility evaluations between June 2024 and December 2025. Key metrics such as semen volume, concentration, motility, and morphology showed marked regional variations, with northern men exhibiting the best results. Despite similar lifestyles, including diet, physical activity, and substance use, researchers concluded that environmental factors, particularly pollution levels, likely account for these differences. The lead researcher, biologist Rocío Núñez Calonge, emphasized that while habits were consistent across regions, environmental exposure remains the most plausible explanation for the observed disparities.

El PaísIndependent🔒CenteryesterdayA study conducted by seven centers of the International UR Group, specialists in assisted reproduction, has compared the semen quality of Spanish citizens from different regions of the country. According to their findings, men from Asturias have sperm quality nearly double that of men from Madrid and significantly higher than those from cities in southern and southeastern Spain. The research, which will be presented at the annual congress of the European Society of Human Reproduction and Embryology in London, confirms data from another 2023 study published in Archives of Medical Research but adds new insights by incorporating a questionnaire filled out by participants to account for lifestyle factors. Despite this, the researchers found that these factors did not influence regional differences in semen quality, suggesting environmental factors such as pollution, toxins, and endocrine disruptors might play a significant role. Experts note that further refinement of the study’s lifestyle factors could lead to more definitive conclusions.
