Most fertility specialists believe that in more than 95% of IVF failures it is due to arrest of the embryos With the advancements in technology, the field of the Laser Assisted Hatching
(AH) a technology which helps embryos to attach to the womb of the woman - has emerged as an art that gives best possible results.
The facility also offers egg and embryo donation, assisted hatching
, sperm bank, and surrogacy options, among others.
The 31 chapters in the second volume address andrology, embryology, the set-up and equipment of an in vitro fertilization laboratory, laboratory management, ethical and legal issues, and reproductive research techniques, including semen examination and interpretation, cryopreservation, intracytoplasmic sperm injection, assisted hatching
and polar body biopsy, intracytoplasmic morphologically selected sperm injection, and polarization microscopy and omics.
A Dutch embryologist, Jacques Cohen, published the first report on assisted hatching
in human embryos (51).
The clinic team led many advances in IVF, including the first ICSI and first egg freezing pregnancies in the US and the first assisted hatching
procedure in the world.
Clearly, any means to improve the proportion of live births per cycle is attractive, both medically and commercially, and many have been tried--such as using support gonadotrophins with luteinising activity, assisted hatching
, and the transfer of 5-day rather than 3-day embryos.
Comparative studies have documented an increased risk for MZ twinning in ART pregnancies that included assisted hatching
(Hershlag et al.
The hospital used a treatment called assisted hatching
Many fertility specialists believe that assisted hatching
helps embryos implant properly in the womb and boosts pregnancy rates, although they have little hard evidence for this.
Indeed, there is evidence that some ART procedures such as intracyto-plasmic sperm injection and assisted hatching
may increase the chance of zygotes splitting Dr.
The assisted hatching
technique developed by Dr Lee and Dr Homa is designed to overcome this problem.
(AH): The outer membrane ("shell") of the embryo is punctured to help implantation in the uterus.
