Semen quality of young men in south-east Spain down by 38 percent in the last decade
Date:1/18/2013

The first comparative study on the evolution of sperm quality in young Spanish men over ten years, headed by researchers at the University of Murcia, reveals that spermatozoid concentration in men between 18 and 23 years in the regions of Murcia and Almeria has dropped by an annual average of 2%.

The suspicion that the semen of Spanish men is losing quality now takes force in the case of young men from Murcia and Almeria.

The 'Andrology' journal has published a multidisciplinary and international study, headed by the Department of Preventative Medicine and Public Health of the University of Murcia (UMU), which demonstrates that "total sperm count and concentration has declined amongst young men in the south-east of Spain in the last decade." More specifically, the decrease amounts to 38%.

The lead researcher, Alberto Torres Cantero, explains to SINC that the study involved "comparing the results obtained by the Medical Research Centre of the University of Granada from the semen of 273 men from Almeria between 18 and 23 years, collected between 2001 and 2002, with those samples collected ten years later by 215 undergraduates from Murcia, all the while ensuring that both sample groups had the same age range and similar characteristics."

The analysis shows that the number of spermatozoids is significantly lower in the subjects from Murcia compared to the participants from Almeria. Average concentration goes from 72 million spermatozoids per millilitre in 2011 to 52 million/ml in 2011, according to Torres Cantero, professor of Preventative Medicine and Public Health at UMU.

Another relevant result is that "40% of those university students analysed in Murcia suffered from alterations in at least one semen parameter (morphology, mobility). Furthermore, all sperm indicators are below the norm in 15% of the sample," states Jaime Mendiola, professor at the UMU and first signatory of the study.
