translated from Spanish: They are warning about a crisis of male fertility

photograph / Internet United States-according to a study conducted in the United States and Spain, infertility is a problem affecting more and more men. Analyzing data from two centers of fertility between 2002 and 2017, the scientists found that during that period of time, the number of patients seeking treatment increased from 8 to 60 thousand.
The researchers also found that semen quality had declined. In many cases, sperm concentration was so low that they needed to resort to in vitro fertilization to conceive.
Ashley Tiegs, one of the researchers, said that it is likely that this worsening of the quality of the sperm is related to factors such as smoking, stress, obesity and exposure to the chemicals in the plastic.
“We know that obesity is increasing and affects the quality of the sperm. Increases the risk of morbidity and mortality, but it can also affect the offspring,”warned Tiegs.
Scientist has admitted that age affects male fertility, but, however, has ruled out this factor in the study, since, in the past 16 years, the average age of men who showed up to receive the treatment did not change, stood in the age of 36.
“It’s a public health problem”, warned Tiegs, of the clinical Reproductive Medicine Associates of New Jersey, United States. At the same time, he noted that the fact that the study was made on two continents demonstrates that it is a global problem.
