Recurrent implantation failure is another indication for the freeze-all strategy

I-24: Recurrent Implantation Failure

Recurrent implantation failure (RIF) has many definitions, but usually authors consider RIF, the failure to achieve a pregnancy fallowing 2-6 IVF cycles in which more than 10 high grade embryos were transferred to the uterus. There are a lot of causes for RIF but two main causes of that are related to embryo and endometrium. Chromosomal abnormalities, zona hardening and problems in culture medi...

Recurrent Implantation Failure Is More Frequently Seen in Female Patients with Poor Prognosis

Onm-8: Recurrent Implantation Failure in IVF/ICSI Cycle

The success of assisted reproduction, although gradually increasing over the years, is still less than satisfactory. Many couples have benefited from this treatment; many have also been left frustrated following multiple failed attempts (Bulent Urman et al. 2005). Repeated implantation failure (RIF), defined as three or more failed IVF attempts or failure of IVF after cumula- Abstracts of the 5...

I-24: The Role of Interleukins, Integrins and Other Proteins in Recurrent Implantation Failure

Embryo implantation represents the most critical step of the reproductive process in many species. Inadequate uterine receptivity is responsible for approximately two-thirds of implantation failures. The cell adhesion molecule (CAM) such as integrins, cadherins, selectins and immunoglobulins intervene to ensure adhesiveness between the embryo and the endometrium. Some recent studies indicate th...

P-195: The Relationship between PAI-1 Polymorphism with Recurrent Implantation Failure (RIF)

Background: RIF is the most common cause of unsuccessful pregnancy after IVF. Among the various causes of RIF, the role of maternal genetic factors is of great significance. PAI-1 polymorphism is one of the notable polymorphisms in this field. In this study, the relationship between this polymorphism and the recurrent spontaneous abortions and infertility in different populations has been inves...
