Association of progesterone receptor polymorphisms with recurrent implantation failure after in vitro fertilization and embryo transfer

P-102: Recurrent In Vitro Fertilization Failure and Hereditary Thrombophilia

a:4:{s:10:"Background";s:363:"The largest percentage of failed in vitro fertilization (IVF) cycles are due to lack of implantation. As hereditary thrombophilia can cause in placentation failure, it may have a role in recurrent IVF failure. The aim of this case-control study was to determine whether or not hereditary thrombophilia is more prevalent in women with recurrent IVF failures.";s:19:"Ma...

Reduced plasma fibrinolytic potential in patients with recurrent implantation failure after IVF and embryo transfer.

BACKGROUND Recurrent implantation failure (RIF) following embryo transfer (ET) is a major continuing problem in IVF. Women with haemostatic defects may be at increased risk of miscarriage and preclinical pregnancy loss. The fibrinolytic system is considered, at present, the key to new thrombotic pathogenic mechanisms. Patients with unexplained recurrent miscarriage have an impairment of fibrino...

The effect of varicocele ligation on oocyte fertilization and pregnancy after failure of fertilization in in vitro fertilization-embryo transfer.

Although varicocelectomy is generally believed to improve semen quality and the hamster egg penetration assay, these parameters do not correlate well with in vitro fertilization (IVF) success. The effect of varicocelectomy on IVF of human oocytes was examined on thirteen couples with normal female fertility, but severe oligozoospermia and the presence varicocele in the males with failure of fer...

Heterotopic pregnancy after in vitro fertilization and embryo transfer.

We have presented a second case of heterotopic pregnancy after IVF-ET. The most likely cause is direct extrusion of embryos through the tubal ostia by the hydrostatic pressure associated with ET. The diagnosis of ectopic pregnancy must be suspected clinically and not ruled out on the sonographic demonstration of an intrauterine pregnancy. Early diagnosis is essential for the prevention of signi...
