Summary

Preimplantation genetic diagnosis (PGD) using fluorescence in situ hybridization (FISH) effectively identifies genetic diseases in embryos. This method helps couples avoid selective abortion and the birth of affected children.

Area of Science:

Reproductive medicine
Clinical genetics

Context:

Couples at higher risk of genetic diseases face difficult reproductive choices.
Preimplantation genetic diagnosis (PGD) offers a potential solution to avoid affected pregnancies.

Purpose:

To evaluate the clinical effectiveness of PGD for couples at high risk of genetic diseases.
To assess the utility of fluorescence in situ hybridization (FISH) in PGD.

Summary:

Four cases underwent ovarian hyperstimulation, oocyte retrieval, and in vitro fertilization.
Blastomere biopsy was performed on 6-8 cell stage embryos, with genetic diagnosis via FISH.
Normal or female embryos were transferred, resulting in one clinical pregnancy and a healthy infant.

Impact:
