Effect of low oxygen concentrations for human embryo in vitro fertilization embryo transfer embryo developmental potential and clinical outcomes

Objective: Discuss of different oxygen partial pressure environments( 20% O 2 5% O 2) for in vitro fertilization embryo transfer embryo developmental potential and clinical outcomes. Methods: 280 cycles with selection in three affiliated hospital human reproductive center from 2012 March to 2012 May of progesterone treatment,respectively IVF( n = 200),ICSI( n = 80). Divided into study group( 5% oxygen) and control group( 20% oxygen). Comparison of the two groups of normal fertilization rate,cleavage rate,good quality embryo rates,biochemical pregnancy rate,clinical pregnancy rate and implantation rate. Results: There was no significance comparing respectively the two groups of normal fertilization rate,cleavage rate,good quality embryo rates,biochemical pregnancy rate,clinical pregnancy rate and implantation rate. Conclusions: In early human embryos in hypoxia envionment were cultured is favorable,Can get a better outcome.
