Inherited genetic diseases have been a problem for some families attempting to conceive a child. If affected parents or carriers of genetic disorders wished to avoid transmitting a condition to their child, they can choose to have prenatal diagnosis of their foetus. Amniocentesis or chorionic villus sampling enables cells from the foetus to be collected and sent for genetic analysis. They could...

Preimplantation genetic diagnosis (PGD) is a reproductive technology used with an in vitro fertilization (IVF) cycle to increase the potential for a successful pregnancy and delivery. The most common applications for PGD include testing for extra or missing chromosomes (aneuploidy screening), familial structural chromosome rearrangements, and diagnosis of genetic disease in couples of increased...

This article covers the rapidly advancing field of preimplantation genetic diagnosis (PGD), the molecular genetic analysis of cells taken from embryos formed through in vitro fertilization (IVF). The article focuses on current practices in patient management, relevant IVF and PGD procedures, molecular methods used in the genetic analysis, and technical difficulties that can affect test results....

Cosmetic micromanipulation is defined as fragment and coarse granulation removal from preimplantation embryos. We report two cases of pregnancies in patients with implantation failure following cosmetic micromanipulation.

CONTEXT Preimplantation genetic diagnosis (PGD) has become an option for couples for whom termination of an affected pregnancy identified by traditional prenatal diagnosis is unacceptable and is applicable to indications beyond those of prenatal diagnosis, such as HLA matching to affected siblings to provide stem cell transplantation. OBJECTIVE To describe preimplantation HLA typing, not invo...
