In page History of in vitro fertilisation:
"The first pregnancy achieved through in vitro human fertilisation of a human oocyte was reported in The Lancet from the Monash University team of Carl Wood, John Leeton and Alan Trounson[1] in 1973, although it lasted only a few days and would today be called a biochemical pregnancy. Landrum Shettles attempted to perform IVF in 1973, but his departmental chairman interdicted the procedure at the last moment.[2][3] There was also an ectopic pregnancy reported by Patrick Steptoe, Robert Edwards and Jean Purdy in 1976.[citation needed]
