The male infertility is the one main reason why Europeans including Danes are having
A man’s fertility depends on the quantity and quality of his sperm. If a man has inadequate ejaculation and the quality of sperm is poor, then it is difficult, sometimes impossible to make children.
Several research conducted by top researchers and doctors show that 3 out of 4 young Danes have bad semen quality. This is the largest research of its kind according to British medical journal Open. Only 23% Danes have optimal semen quality which means more than 40 million reproductive cells per mililtre. The research reveals, that 15 % Danes have extreme difficulty to make partners pregnant, 25% Danes have to wait long to have a child and the quality of sperm of 5% Danes are so bad that they can not make children.

Danes have been focus for this problem because Denmark state hospital Rigshospital conducted the research and the Danish scientist Niels Jørgensen led the research.
In fact the problem is not a Danish problem. A similar research was carried out in Finland and guess what, their sperm quality was worse than Danes. Results among the Swedish and Norwegian are no better.
A very recent research finds that sperm counts among Western men have more than halved in the last 4 decades but the reason behind it is unclear, news source The Guardian Sperm counts among western men have halved in last 40 years – study 185 studies have been conducted among 43000 men in Western countries.
Studies find, the sperm concentration fell from 99 million per ml in 1973 to 47.1 million per ml in 2011 – a decline of 52.4% among Western men.
The Danish University Southern university of Denmark was not involved with this research but their own research shows similar result. Human semen quality in the new millennium: a prospective cross-sectional population-based study of 4867 men
British researchers think that this this is very alarming sign. If the deterioration of semen quality continues, that could be end of human race or extinction.
Doctors believe that the low semen quality is not the problem for only Western males, it could be for entire population. We do not the quality of semen among Asian and African males because no research has been conducted their.
In short, there are overwhelming evidences that poor semen quality is the main reason for male infertility and less children as a result.
