Researchers from the Human Nutrition Unit of the Rovira i Virgili University and the CIBERobn in collaboration with researchers from the University of Utah (USA), researchers from the Ahvaz Jundishapur University and the National University of Córdoba (Argentina),have found that overweight and/or obesity were associated with low semen quality parameters (i.e., semen volume, sperm count and concentration, sperm vitality, total motility and normal morphology) and underweight category was likewise associated with low sperm normal morphology. The results of the study have been published have been published in the prestigious scientific journal Obesity Reviews.
Infertility affects between 10 and 15% of all couples of reproductive ages and can be caused by a wide variety of factors: genetic, physiological, environmental and nutritional. Although there is increasing scientific evidence about the role of nutrition in sperm quality, there is still controversy about the role of overweight, obesity and low weight in sperm parameters.
The researchers carried out a systematic review and meta-analysis of all the existing observational scientific literature, evaluating the association between adiposity(normal weight, overweight, obesity, and low weight) and the sperm quality determined by a seminogram.
