DONATE SPERM

A UK national sperm bank - charged with reversing a growing shortage of donor sperm - has started work in Birmingham.

Fertility clinics have become increasingly dependent on imported sperm giving rise to the so-called "Viking babies" phenomenon.

Meanwhile, data from the fertility regulator shows a 10th of IVF cycles are dependent on donated sperm or eggs.

And a third of procedures using donated material were for same-sex couples or single women.

The number of UK-based sperm donors has been increasing since 2004. However, demand has increased even faster.

Denmark and the United States have become major suppliers of sperm to British women.
