1989
First report on biopsy of human preimplantation embryos and sexing by DNA amplification. (Handyside AH, Pattinson JK, Penketh RJ, Delhanty JD, Winston RM, Tuddenham EG. Biopsy of human preimplantation embryos and sexing by DNA amplification. Lancet. 1989;18;1:347-9).
First report on the use of laser techniques in the field of assisted reproduction for application in gametes or embryos (Tadir Y, Wright WH, Vafa O, Ord T, Asch RH, Berns MW. Micromanipulation of sperm by a laser generated optical trap. Fertil Steril. 1989 Nov;52(5):870-3).
Gonen and her colleagues in Toronto pioneered the use of ultrasound for endometrial quality (thickness and pattern) related to IVF pregnancy. (Gonen Y, Casper RF, Jacobson W, Blankier J. Endometrial thickness and growth during ovarian stimulation: a possible predictor of implantation in in vitro fertilization. Fertil Steril. 1989;52(3):446-50).
Embryo biopsy technique was developed in mice by Professor Alan Trounson and Leeanda Wilton. (Wilton LJ, Trounson AO. Biopsy of preimplantation mouse embryos: development of micromanipulated embryos and proliferation of single blastomeres in vitro. Biol Reprod. 1989;40(1):145-52).
In vitro fertilization (IVF) is a process by which egg cells are fertilised by sperm outside the body, in vitro. IVF is a major treatment in infertility when other methods of assisted reproductive technology have failed. The process involves hormonally controlling the ovulatory process, removing ova (eggs) from the woman's ovaries and letting sperm fertilise them in a fluid medium.
