own stem cells detect a deterioration in sperm quality and increased testicular cancer How to get

MADRID, 4 Mar. (EUROPA PRESS) -

Researchers at the University of Turku in Finland have found a" significant "deterioration in the quality of sperm and an increased incidence of testicular cancer in recent years, as suggested, could be related to increased exposure to chemicals.

research, the results of its latest issue published in the journal 'International Journal of Andrology ", analyzed the status of semen from a group of Finnish men of different ages, after previous studies have confirmed that the residents of this Nordic country have high levels of sperm concentration highest in the world.

Specifically, the study included men born between 1979 and 1987, who did a follow up to the 19 years between 1998 and 2006. Thus, they found that those born in the late 80's had fewer sperm than those born at the beginning of the decade.

Men born between 1979 and 1981 had about 227 million sperm on average, while those born in 1987 the average was just 165 million.

addition, the same study found a higher incidence of testicular cancer in men born around 1980, when comparing the data from this study with the incidence of these tumors in 1950.

explains one of the authors of the study, Jorma Toppari profess, "This trend suggests that there are simultaneously the same cause in both cases, hence it is necessary to identify the cause to" introduce the largest possible preventive. "

For his part, Professor of Andrology at the University of Sheffield, Allan Pacey, has acknowledged speaking to the BBC, picked up by Europa Press, that there is already some concern since long time ago "the possibility that younger men have lower production sperm than their parents and grandparents to their age. "

Something that, as pointed Pacey, the results of the study data show" very rigorous ".

" The best hypothesis we have to explain the decrease in the number of sperm is that chemicals in food or the environment are affecting the development of the testicles of children in the womb or in early life, "said the expert.

Pacey A circumstance which recognizes that" only apparent at puberty and trying to become parents, "which makes" it difficult to study. "

Therefore, increasing demands research in this field to identify hazardous chemicals to "protect future generations."
