Abstract:
OBJECTIVETo establish the method of detecting oocyte aneuploidy by spectral karyotyping (SKY).
METHODSThe unfertilized oocytes were fixed 1-2 days after oocyte retrieval. Spectral karyotyping was performed according to the protocol.
RESULTS64% of oocytes were normal, 36% of oocytes were aneuploidy, of which 22% were due to nondisjunction and 14% unbalanced predivision.
CONCLUSIONSKY is an effective method for detecting oocyte aneuploidy. Both nondisjunction and unbalanced predivision are involved in oocyte aneuploidy formation.
