Journal ArticleDOI
Significance of large nuclear vacuoles in human spermatozoa: implications for icsi
J. G. Franco,R. L. R. Baruffi,A.L. Mauri,Claudia G. Petersen,J. B. A. Oliveira,Laura D. Vagnini +5 more
TL;DR: The results show an association between LNV and DNA damage in spermatozoa, and support the routine morphological selection and injection of motile spermutozoa at high magnification for ICSI.
Journal ArticleDOI
The effects of male age on sperm DNA damage in an infertile population
Laura D. Vagnini,R. L. R. Baruffi,A.L. Mauri,Claudia G. Petersen,Fabiana C. Massaro,Anaglória Pontes,J. B. A. Oliveira,Jose G. Franco +7 more
TL;DR: TUNEL assay clearly demonstrates an increase in sperm DNA damage with age, which is significantly lower in Group I than in Group II or III and regression analysis demonstrated a significant increase in semen DFI with age.
Journal ArticleDOI
Implantation failures: Success of assisted hatching with quarter-laser zona thinning
Claudia G. Petersen,A.L. Mauri,R. L. R. Baruffi,J. B. A. Oliveira,Fabiana C. Massaro,Kay Elder,Jose G. Franco +6 more
TL;DR: The data demonstrate that qLZT-AH is an effective strategy for improving the implantation of embryos in patients with repeated implantation failures.
Journal ArticleDOI
Motile sperm organelle morphology examination is stricter than Tygerberg criteria
J. B. A. Oliveira,Fabiana C. Massaro,A.L. Mauri,Claudia G. Petersen,A. P. M. Nicoletti,R. L. R. Baruffi,Jose G. Franco +6 more
TL;DR: Despite the highly positive correlation, MSOME is a much stricter criterion of sperm morphology classification, since it identifies vacuoles and chromatin abnormalities that are not evaluated with the same precision by the analysis of Tygerberg criteria.
Journal ArticleDOI
Relationship between visualization of meiotic spindle in human oocytes and ICSI outcomes: a meta-analysis.
Claudia G. Petersen,J. B. A. Oliveira,A.L. Mauri,Fabiana C. Massaro,R. L. R. Baruffi,Anaglória Pontes,Jose G. Franco +6 more
TL;DR: According to the meta-analysis, the results showed statistically significant higher fertilization rate when the meiotic spindle was viewed than when it was not, and this observation has clinical relevance mainly in countries where there is a legal limit on the number of oocytes to be fertilized.
