Journal ArticleDOI
Predictive value of testicular histology in secretory azoospermic subgroups and clinical outcome after microinjection of fresh and frozen–thawed sperm and spermatids
Mário Sousa,Nieves Cremades,J. Silva,C. Oliveira,L. Ferraz,J. Teixeira da Silva,Paulo Viana,Alberto Barros +7 more
TL;DR: Histopathological subgroups were positively correlated with successful gamete retrieval and injection of intact round-spermatids showed very low rates of fertilization and no pregnancies.
Journal ArticleDOI
Treatment by testicular sperm extraction and intracytoplasmic sperm injection of 65 azoospermic patients with non‐mosaic Klinefelter syndrome with birth of 17 healthy children
C. Madureira,M. S. Cunha,Mário Sousa,Ana Paula Neto,Manuela Pinho,Paulo Viana,A. Gonçalves,Jorge Sa Silva,J. Teixeira da Silva,C. Oliveira,L. Ferraz,Sofia Dória,Félix Carvalho,Alberto Barros +13 more
TL;DR: Clinical and embryological outcomes of 65 azoospermic patients with non‐mosaic Klinefelter syndrome treated by testicular sperm extraction, followed by intracytoplasmic sperm injection, revealed higher fertilization and clinical pregnancy rates with fresh spermatozoa, with no differences regarding implantation or newborn rates.
Journal ArticleDOI
Experimental vitrification of human compacted morulae and early blastocysts using fine diameter plastic micropipettes
Nieves Cremades,Mário Sousa,Jorge Sa Silva,Paulo Viana,Susana Sousa,C. Oliveira,J. Teixeira da Silva,Alberto Barros +7 more
TL;DR: The survival rates of human compacted morulae and early blastocysts after vitrification with this simple technique are similar to those reported in the literature achieved by slow cooling and other vitrification protocols.
Journal ArticleDOI
Embryological, clinical and ultrastructural study of human oocytes presenting indented zona pellucida.
Mário Sousa,J. Teixeira da Silva,J. Silva,M. S. Cunha,Paulo Viana,Elsa Oliveira,Rosália Sá,Celia Azevedo Soares,C. Oliveira,Alberto Barros +9 more
TL;DR: Oocytes with this novel described dysmorphism (indented ZP) are associated with low maturity, pregnancy and live-birth delivery rates.
Journal ArticleDOI
P-064 Clinical outcomes of 127 patients with recurrent implantation failure treated with testicular sperm aspiration (TESA)
Marta Sousa,Mariana Cunha,M. Pereira,J. Teixeira da Silva,Ana I. Gonçalves,Paulo Viana,Nuno Barros,Soraia Pinto,M. Geraldo,C. Oliveira,Pedro Xavier,Luís Ferraz,A. Juan,Alberto Barros +13 more
TL;DR: The present study compares 127 treatment cycles, 80 with testicular sperm (17 cases repeated TESA) and 47 with ejaculated sperm from the same patients performed at the present IVF clinic, finding no pregnancy ensued from these cycles.
