Purpose: After aneuploidy, failure of oocyte activation, resulting in premature chromosomal condensation (PCC), is considered as the second cause of failed fertilization post ICSI. Oocyte quality has been shown to affect PCC formation, and since this study sought to evaluate the effect of sperm chromatin anomalies on the PCC, mice metaphase II oocytes were used. Materials and Methods: Metaphas...
Abstract Study question Does CultActive© improve reproductive outcomes of ICSI cycles in cases low fertilization rate and normal rate? Summary answer The application after improves rates only clinical indication failure. What is known already Oocyte activation deficiency attributed the majority to failure cycles, these can be corrected by increasing initial levels calcium (Ca2+) using assisted ...
OBJECTIVE The aim of the current study was to evaluate the effect of an oral pretreatment with a mix of myo-inositol (Myo-Ins), folic acid, vitamin E, L-carnitine, L-arginine and selenium (Folandrol, Exeltis, Hungary) and subsequent direct Myo-Ins incubation of spermatozoa before Physiological Intra-Cytoplasmic Sperm Injection (PICSI) procedures in infertile couples due to oligoasthenoteratozoo...
Semen analysis is the frontline and old reliable test in the assessment of male fertility, but it failed to provide absolute prediction of sperm function and its fertilizing ability. A wide variety of internal and external factors affect sperm function without discernible and significant effects on semen analysis. Oxygen toxicity and oxidative stress (OS) are inherent challenge of living cells ...
