[Identification of sex in mouse preimplantation embryos by indirect immunofluorescent assay]. Indirect immunofluorescent assay was used for detecting male-specific H-Y antigen on preimplantation embryos. Our results showed that, embryos examined, 54.1% were H-Y positive (male) and 45.9% were H-Y negative (female). Significant difference was not found between natural sex ratio of kunming strain mouse (male: 52.1%; female: 47.9%) and our results (P greater than 0.05). Moreover, the results sequentially were confirmed by cytogenetic method. 75.50% H-Y positive embryos were male and 82.97% H-Y negative embryos were female respectively (P less than 0.01). Some factors influencing the accurency of sex selection with indirect immunofluorescent assay were also discussed.
