Talking about Assisted Hatching
03/NOV/09
Assisted Hatching (AH) is a technique that involves creating a small hole in the outer membrane of the embryo to facilitate their implementation, it takes place moments before making the transfer, usually on the third day of embryo culture; and is generally indicated in women older than 38 years, in cycles with previous decisions of implantation and frozen embryo transfers with the aim of improving success rates. In embryos with altered morphology, with hatching, small aim is reach cell fragments that can impair their quality and development.
Women over 38 years
The implantation rate decreases progressively after age 37 became more evident beyond age 40. The process of ovarian aging favors the increase of chromosomal alterations in the egg that can impair the ability of the embryo to implant. Using the EA can improve outcomes in this patient group.
Implantation failures
When a patient has had two failures of implantation, whatever their age, AD is considered necessary as technical support for further attempts since it favors the implantation of the embryo early in development to allow more adequate synchrony between the embryo and the endometrium .
Frozen embryos
The pregnancy and implantation rates in frozen embryo transfers are usually low compared with fresh embryos. The hardening of the outer membrane along with the presence of dead cells generated by the process of freezing and thawing reaches compromise embryo viability. EA is achieved through the restoration of capacity development and implantation of such embryos after thawing.
Embryos with altered morphology
The thickness of the outer membrane of the embryo should decrease as it develops in the crop so the failure in the process of thinning can prevent implantation of the embryo.
Moreover, the presence of cell fragments is a common feature in human embryos. Still, it is known that the higher the percentage of smaller fragments is the ability of the embryo to develop properly. Therefore, by the EA and eliminating some types of fragment, we can restore the capacity of development of these embryos.
This process is incorporated in Assisted Reproduction Laboratories with the aim of improving pregnancy rates and implantation but requires skill and experience of the embryologist micromanipulation techniques that do not run it since the very carefully carries the risk of damaging the embryo, subtracting chance of success.
The group ANAC, as representatives of the Quality of Reproductive Medicine, we offer our patients all the techniques available to achieve the dream of parenthood.
