The Solomor Epidemy

In Denmark, one in 10 babies conceived with donor sperm is born to a woman without a partner. It is called a solomor (from Solo Amor). Denmark has the highest number of births by assisted fertility treatment in the world, and 10% solomor is just the start of a powerful trend.  The reason may be social (unwillingness to become a father) and/or biological. The sperm quality among young Danish men is low, with a quarter barely able to impregnate his partner (from Rigshospitalet the National Hospital of Denmark).  

In the USA, AID results in about 100,000 babies per year — 2% of all births. The rate is higher in Japan (5 percent) and Denmark (10 percent).

Denmark is trying to solve the problem through unprecedented State support to anyone willing to make a baby. That system is feasible while the population is homogeneous as Denmark. May be I am wrong, because France is diverse and the State provides much social assistance, although diversity in Europe is a relatively recent development that is still undigested and not reflected in the laws and the social arrangements. 

The general unwillingness of young males to marry and form families is not of today. In Solon's Greece it was necessary to force by law everyone to marry. In Sparta, unmarried men were interrogated frequently by the police and punished and imposed shaming inabilities. In Augustus's Rome, the Emperor himself publicly harangued and shamed the reluctant.  Even today, in most countries, married men pay less tax.
