Founding pioneers of IVF update: Innovative researchers generating livebirths by 1982.

This commentary adds accuracy and interesting information to the story of the founding pioneers of IVF which was published in this journal in 2018, at the 40 anniversary of the first IVF livebirth, namely Louise Joy Brown born 25 July 1978. Table 1 in that first publication is now updated to reflect extended information about Team 1 comprising the acknowledged "Fathers of IVF", but whose work is better tabulated as Team 1a from the NHS days in Oldham; and Team 1b covering the new period of private practice at Bourn Hall in Cambridge. With the passing of pioneer Ian Craft, co-author of the first article, further information came to light at his memorial service. There has now been some adjustment to the last few months of 1982, with correct inclusion of Israel into the list along with an interesting exposé of the two major pioneer facilities of that country. The previously cited third Australian groups (Team 12) have now been appropriately relegated to 1983, a year which experienced a plethora of IVF facilities around the world and the beginning of the IVF population boom.
