Way back in the 1940s a man, Bertold Wiesner, started a fertility clinic with his wife and helped in the conception 1500 children. He had a slightly more hands on approach than most, because he used his own sperm to conceive 600 of those kids. We have Rachel Kiki on to talk about this as they are Wiesner’s grandchild! We also go into the invention of artificial insemination and IVF.
