FISH [fluorescent in situ hybridisation] is used for the analysis of chromosomes and is the preferred method of embryo sexing for patients at risk of transmitting X-linked diseases.  3, record 1, English, - embryo%20sexing

It is now possible to detect some genetic diseases in very early embryos by a procedure known as preimplantation genetic diagnosis(PGD). [...] PGD has primarily been used to determine the sex of embryos for couples who carry a sex linked disease, such as haemophilia or muscular dystrophy,(which affect only boys). Embryo sexing is achieved by subjecting the biopsied cells to fluorescent in situ hybridisation(FISH) where the X-and Y-chromosomes in the cells are labelled red and green.  4, record 1, English, - embryo%20sexing

Sexage d'embryon. Détermination du sexe d'un embryon avant la naissance. Généralement accomplie par la réaction de polymérisation en chaîne de l'ADN extrait d'un échantillon de tissu embryonnaire. Elle dépend de la disponibilité de marqueurs fiables pour différencier les chromosomes sexuels.  2, record 1, French, - d%C3%A9termination%20du%20sexe%20de%20l%27embryon

La réalisation du caryotype foetal doit être proposée en cas de diagnostic prénatal de maladie génique récessive liée au sexe comme la myopathie de Duchenne ou l'hémophilie, la détermination du sexe de l'embryon est nécessaire pour évaluer un premier risque ; seul les garçons sont atteints (un sur deux).  3, record 1, French, - d%C3%A9termination%20du%20sexe%20de%20l%27embryon

Sexaje de embriones. Determinación del sexo del embrión antes del nacimiento. Generalmente se realiza aplicando la reacción en cadena de la polimerasa para amplificar el ADN extraído de una muestra del tejido embrionario.
