ART failure: oocyte contributions to unsuccessful fertilization [PDF]

Human Reproduction Update, 2008
The complexity of fertilization failure during assisted reproductive technologies (ART) is often under-appreciated, as this failure can occur at any number of essential mechanistic and cellular events. Importantly, successful fertilization is heavily dependent upon inherent qualities of the oocytes, and thus reliant upon fidelity of oocyte maturation ...

Novel mutations in the PLCZ1 gene associated with human low or failed fertilization

Molecular Genetics & Genomic Medicine, 2020
Background Fertilization failure (FF) is a complex reproductive disorder characterized by the failure of pronuclei formation during fertilization. In addition to some cases caused by iatrogenic problems and known genetic factors, there are still many ...

Failed Fertilization in ART: What are the Causes and Methods to Improve Fertilization

Fertility & Reproduction, 2023
Introduction of clinical ICSI made a revolution in achieving higher fertilization in ART programs. However, ICSI does not completely eliminate the risk of fertilization failure as total fertilization failure (TFF) occurs in 1-3% of ICSI cycles. TFF leads

Assisted oocyte activation following ICSI fertilization failure [PDF]

Reproductive BioMedicine Online, 2014
The capacity of intracytoplasmic sperm injection (ICSI) to permit almost any type of spermatozoa to fertilize oocytes has made it the most successful treatment for male factor infertility. Despite its high success rates, fertilization failure following ICSI still occurs in 1-3% of couples.

Fertilization capacity with rainbow trout DNA-damaged sperm and embryo developmental success [PDF]

, 2010
Mammalian spermatozoa undergo a strong selection process along the female tract to guarantee fertilization by good quality cells, but risks of fertilization with DNA-damaged spermatozoa have been reported.

Chronic endometritis in In-Vitro fertilization failure patients [PDF]

Global Journal of Fertility and Research, 2020
Introduction: Chronic endometritis (CE) is a common cause of infertility in asymptomatic patients and its diagnosis and treatments improved assisted reproduction technique outcome in most of the specialized centers. Diagnosis of CE in endometrial biopsy by Hematoxylin and Eosin (H&E) stain is hard to identify chronic inflammatory cells from the ...
