Another article in the Guardian explores the topic. https://www.google.com/amp/s/amp.theguardian.com/lifeandstyle/2013/nov/02/men-single-dad-father-surrogacy-adoption
Brief mention of Ian Mucklejohn the first British man to go it alone through surrogacy. Legend. And we can't forget Christian Ronaldo and Ricky Martin who both conceived
children through surrogacy using egg donors. Lots more examples of more everyday single hereos though who aren't celebrities in this article. Mainly US focused.
