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

Fertilization failure and gamete health Is there a link
Fertilization is a hallmark event of sexual reproduction marked by the fusion of male and female gamete to form zygote. It is a highly complex, yet a robust process that is intricately regulated by various signalling molecules. A healthy fertilization is determined by the quality of zygote which is contingent on the health of egg and sperm.

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

ART failure: oocyte contributions to unsuccessful fertilization [PDF]
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 ...

THE FAILURE OF THE COPPER IUD TO INHIBIT FERTILIZATION IN THE RABBIT [PDF]
The effect of intra-uterine devices (IUDs) in rabbits is variable. Depending on size, intra-uterine threads and plastic IUDs cause incomplete and localized reductions in fertility (Brown & Foote, 1966; Marston & Chang, 1969). Recently, the use of copper coils in rabbits and copper wire (in combination with plastic `T' devices) in humans has ...

Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

BackgroundInfertility affects approximately 15% of couples worldwide, with male factors accounting for nearly 50% of cases. Intracytoplasmic sperm injection (ICSI) has become the standard treatment for male factor infertility, but outcomes vary ...
