Freezing sperm a hot business

The universal second-child policy has led to a boom in demand for sperm freezing services among Chinese men, as more attempt to extend prime fertility into later life as part of their plans for another child, according to fertility specialists.

The sperm bank in Hangzhou, Zhejiang province, saw a twofold increase in the number of men who froze their sperm to preserve fertility last year compared with 2016.

Zhang Junrong, a leading physician at the government-run facility, attributed the increase largely to the second-child policy implemented nationwide in January 2016.
