The aim of the present work was to present the outcomes of the patients with Y-chromosome microdeletions treated by intracytoplasmic sperm injection (ICSI), either using fresh (TESE) or frozen-thawed (TESE-C) testicular sperm and ejaculated sperm (EJAC). The originality of this work resides in the comparisons between the different types of Y-microdeletions (AZFa, AZFb, and AZFc) and treatments,...

BACKGROUND For human ICSI, sperm are normally immobilized immediately prior to injection. However, there are some situations when only sperm of questionable viability are available. There are few evaluations of fertilization or developmental problems in human or animal models using sperm having known intervals between immobilization and injection. METHODS Immobilized human sperm were maintain...

Chromosome stability was maintained in mouse spermatozoa after freeze-drying or freezing without cryoprotection in a simple Tris.HCl buffer containing EGTA (50 mM) and NaCl (50 mM). The ability of spermatozoa to activate oocytes spontaneously was not destroyed by freeze-drying or freezing without cryoprotection in this solution. Embryos derived after injecting oocytes with sperm heads from rehy...
