For many months I’ve been puzzling over repeated reports of a sperm shortage in the UK. Generally (as you’ll see if you look at some of my earlier posts) the shortage is attributed to a change in UK law that ensures that those conceived with third-party sperm can learn the identity of the provider when they turn 18. As I wrote in January, what’s perplexing is that the statistics released by the HFEA do not appear to bear out the assertion that the number of men providing sperm has dropped since the law changed.
At last, someone has offered an explanation. This comment from The Guardian suggests the real problem is that most of the sperm available is not being used. For the moment, I’m just going to link to this, because I’m so gratified that someone else was bothered by this.
