      There was a transient biochemical pregnancy reported by Australian Foxton School researchers in 1953. John Rock was the first to extract an intact fertilized egg. In 1959, Min Chueh Chang at the Worcester Foundation, proved fertilization in vitro was capable of proceeding to a birth of a live rabbit. Chang's discovery was seminal, as it clearly demonstrated that oocytes fertilized in vitro were capable of developing, if transferred into the uterus and thereby produce live young.
      The first pregnancy achieved through in vitro human fertilization of a human oocyte was reported in The Lancet from the Monash University team of Carl Woods, John Leeton and Alan Trounson in 1973, although it lasted only a few days and would today be called a biochemical pregnancy. Landrum Shettles attempted to perform an IVF in 1973, but his departmental chairman interdicted the procedure at the last moment. There was also an ectopic pregnancy reported by Patrick Steptoe and Robert Edwards in 1976.
