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...

Origin of heart failure: cardiac or generalized myopathy?

v the neuroendocrine response, which was once believed to be a compensatory reaction of the organism to counteract the ‘failure’ conditions, is now considered a detrimental response of the body. As such, it is recommended that this response be treated; v positive inotropic drugs, which were considered the logical treatment solution for the failing heart, do — paradoxically — increase mortality ...

Recurrent triploidy of maternal origin.

We report the occurrence of triploid preimplantation embryos following in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) in a woman with two previously-identified triploid conceptuses which spontaneously underwent fetal demise at 10 and 23 weeks' gestation. An error in maternal meiosis II is proposed as the most likely cause.
