Recurrent implantation failure (RIF) refers to failure to achieve a clinical pregnancy after transfer of at least four good-quality embryos in a minimum of three fresh or frozen cycles in a woman under the age of 40 years. The failure to implant may be a consequence of embryo or uterine factors. Unsuccessful attempts with the transferring of high grade embryos, due to thin (≤6 mm) endometrium, with or without variations in vascularity is called endometrial RIF. HeilaPearl is a natural intensifier for regenerative forces. HeilaPearl extract, purify and empower multiple regenerative molecules (growth factors) and an important anti-inflammatory (anti-destructive) factor, called "interleukin 1 receptor blocker" from your own blood. These molecules are able to regenerate endometrial tissue leading to successful implantation.
