Cytogenetic analysis of spontaneously activated noninseminated oocytes and part...
Almeida-Santos, T; Dias, C; Henriques, P; Brito, R; Barbosa, A; Regateiro, FJ; Almeida-Santos, APURPOSE:Spontaneous parthenogenetically activated noninseminated oocytes and failed fertilized oocytes after ART activated by puromycin were studied to assess cleavage ability and the cytogenetic constitution of the resulting embryos. METHODS: Failed fertilized oocytes were exposed to puromycin, and whenever activation occurred, they were further cultured until arrest of development. FISH was used to assess the...

Almeida-Santos, T; Dias, C; Brito, R; Henriques, P; Almeida-Santos, APURPOSE: Development of a hybridization technique for spermatozoa allowing the preservation of the head morphology. METHODS: FISH analysis of fixed semen samples from oligoasthenoteratozoospermia (OAT) patients with a normal somatic karyotype attending the Cytogenetics and the IVF Laboratories of a University hospital for semen analysis. In situ hybridization with centromeric probes for chromosomes X, Y, and 18...
