Is chromosome analysis mandatory in the initial investigation of normovulatory women seeking infertility treatment?
GROUND: There is no agreement about the frequency of chromosomal abnormalities (CAs) in the female partner of an infertile couple and therefore there is no evidence base for determining whether karyotype analysis is mandatory before the initiation of infertility treatment. The aim of this prospective study was to estimate the prevalence of karyotype abnormalities in normovulatory women attending an infertility clinic and compare it to that known to be present in the newborn female population. METHODS: Cytogenetic testing was performed in 1206 women with normal ovulatory cycle seeking infertility treatment. At least 15 GTG-banded metaphases were analysed in each case. In the case of a structural abnormality, fluorescent in situ hybridization (FISH) analysis and high resolution banding (HRB) were performed on a new blood sample to elucidate the aberration. When mosaicism was suspected, the number of analysed metaphases was increased to a total of 115 and an additional analysis of 200 met
