a laboratory procedure involving the creation of an opening in the zona pellucida, or outer membrane, of a fertilized egg or embryo. This procedure is intended to help the embryo emerge from the covering and implant in the uterus; in some women of advanced reproductive age, normal hatching of the embryo may not happen without such assistance.
A laboratory procedure that chemically dissolves an embryo surface to improve the likelihood of implantation.
Assisted hatching is a form of embryo micromanipulation whereby a hole is artificially made in the embryo's covering to increase the chance of embryo development. Selective assisted hatching may increase the chance of pregnancy in women over 40 years of age, women with elevated basal FSH levels, women with a history of implantation failure, or in women with embryos having a thick layer surrounding the oocyte (zona pellucida).
A small opening is made in the outer shell of the embryo to improve the chances of implantation.
Technique involving the artificial creation of an opening in the outer covering of the zona pellucida of the embryo. Used to help the normal growing embryo to emerge from the covering in order to implant properly in the uterus. Can be done by use of lasers, chemicals or mechanically.
AH is a micromanipulation procedure in which an opening is made in an embryo's outer shell (zona pellucida). This opening allows the embryo to more easily "hatch" and thus implant in the woman's uterus.
The thinning of the shell or creation of a small hole in the zona of an embryo.
To help an embryo break through the zona pellucida (a protective, encapsulating shell) and successfully implant in the uterus, a doctor may thin down or create a small hole in this shell.
Embryo micromanipulation creates a hole in the embryo's covering to increase the chance of implantation. This technique is used for older women, who have a history of failed implantations, or elevated basal FSH levels.
Microscopic procedure ( micromanipulation ) to break up the zona pellucida (a thick protein coating surrounding the egg ).
A technique used to help the embryo escape from its zona pellucida (shell). An embryo needs to hatch before implantation can occur.
The zona pellucida or coating of an embryo is opened mechanically, chemically or with a laser, with the aim of assisting the embryo to emerge and improve implantation and pregnancy rates.
Micromanipulation process that dissolves part of the zona coating with an acid solution. Performed just prior to embryo transfer.
The mechanical, chemical or laser breaching of the gelatinous coating of the eggs. Also known as zona drilling.
Thinning of the embryo's outer egg shell (zona pellucida) prior to embryo transfer. Indicated for couples with advanced maternal reproductive age, elevated FSH levels, and prior repetitive IVF failures.
A procedure that dissolves the embryo surface to help the embryo implant.
making a small hole in the zona pellucida (gel-like covering of embryo) to facilitate implantation of the developing embryo in the uterine wall.
Thinning of or mechanical nicking of the zona pellucida prior to transferring the embryo into the uterus.
A small hole is made in the outer shell around the embryo (the zona pellucida) before transfer to the uterus
A micromanipulation technique in which the shell around the egg (the zona pellucida) is opened or thinned to facilitate the embryo hatching process and subsequent implantation. (details)
A type of micromanipulation procedure designed to improve implantation, whereby the embryologist makes a chemical opening on the zona pellucida of an embryo to allow the cleaved embryo to exit prior to implantation.
the process where special techniques are used to help the embryo come out of its shell (zona pellucida) ready for implantation.
A technique in which the zona pellucida (outer shell of the egg) is chemically or mechanically thinned prior to embryo transfer in order to improve the likelihood of subsequent hatching.
Failure of an embryo to inplant into the uterine wall may be as a result of the embryo's failure to hatch out of the zona pellucida (shell). Assisted hatching techniques rupture the zona pellucida prior to implantation, in order to improve the chances of implantation occuring.
A sophisticated, micromanipulation technique for perforating the shell surrounding the egg (the zona pellucida) so that the embryo can "break out" and implant in the uterus.
A technique done in the laboratory whereby a small opening is made in the zona pellucida of the embryo in order to facilitate implantation.
A microinjection procedure which chemically dissolves the embryo surface to facilitate implantation.
The mechanical, chemical or laser breaching of the gelatinous coating of the egg (zona pellucida).
The mechanical, laser or chemical breaching of the zona pellucida (outer layer) of the egg
A micromanipulation technique which involves thinning out the zona pellucida prior to transferring the embryo into the uterus. This procedure may improve implantation rates in some women.
An in vitro procedure in which the zona pellucida of an embryo is perforated by chemical, mechanical, or Click for full entry Life After Breast Cancer
A laboratory procedure which involves creating a small slit in the shell (zona pellucida) of the human embryo to assist it with escape from its shell and increase its likelihood of implantion in the uterus. Also known as partial zona dissection.
