1996
The Valencia group reported on the first pregnancy employing cryopreserved testicular sperm following IVF-ICSI. . (Gil-Salom M, Romero J, Minguez Y, Rubio C, De los Santos MJ, Remohà J, Pellicer A. Pregnancies after intracytoplasmic sperm injection with cryopreserved testicular spermatozoa. Hum Reprod. 1996;11(6):1309-13).
Discovery that some men with severe oligoasthenospermia have deletions in the Y-chromosome (Reijo R, Alagappan RK, Patrizio P, Page DC. Severe oligozoospermia resulting from deletions of azoospermia factor gene on Y chromosome. Lancet, 1996, 11;347(9011):1290-3).
Jurisicova from the Casper group was the first to recognize that preimplantation of human embryo fragmentation involved programmed cell death. (Jurisicova A, Varmuza S, Casper RF. Programmed cell death and human embryo fragmentation. Mol Hum Reprod. 1996;2(2):93-8).
Casper and his colleagues were the first to demonstrate and introduce the use of the hypo-osmotic swelling test for selection of immotile sperm for ICSI. (Casper et al. 1996 Fertil Steril 65:972)
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.
