Evaluation of Soluble L-Selectin (CD 62L)Level in Embryo Culture Media to Embryo Quality and Implantation Rate

Abstract

Background : Although progress was made in an in vitro fertilization (IVF) tech­ niques, the majority of transferred embryos fail to implant. Morphology embryo scoring is the standard procedure for most of IVF centers for choosing the best embryo, but remains limited since even the embryos classified as (top quality) may not implant. Determining molecular mechanisms of human embryo implan­ tation is an extremely challenging task due to the limitation of materials and significant differences underlying this process among mammalian species. L-Se­ lectin and its ligand carbohydrate have been proposed as a system that mediates initial adhesion of human blastocysts to the uterine epithelia. Objectives: Quantitative evaluation of soluble L-Selectin molecule in an in-vitro culture media used for in vitro fertilization. Determine cut-off value of soluble L-Selectin quantity to be as qualitative predictor of successful implantation Patients and Methods: This prospective study was undertaken in the High In­ stitute of Infertility diagnosis and assisted Reproductive Technologies/ Al-Nah­ rain University/ Baghdad/ Iraq, during the period from September2017 to April 2018.A total of 74 infertile women were underwent controlled ovarian hyper stimulation for intracytoplasmic sperm injection cycle. Flexible antagonist pro­ tocol was used as ovulation induction protocol in all the cases .culture media L-Selectin level were measured on the day of embryo transfer by using Enzyme linked immune sorbent assay (ELISA) for all cases . Comparison in culture me­ dia L-Selectin was done to all cases. Results: There was no significant difference between pregnant and non-pregnant groups in age , BMI, and level of basal hormone FSH, LH , AMH and E2 in the day of hCG injection, and significant difference in the level of L-Selectin in pregnant compared to non-pregnant groups. Conclusion: Level of L-Selectin concentration in embryo culture media can be used as predictor of ICSI success
