Influence of the morphological aspect of embryos obtained by in vitro fertilization on their implantation rate.

摘要: In a series of 500 transfers embryos obtained by in vitro fertilization, we examined the implantation rate 1356 transferred utero. The average per embryo was 15.1% and remained relatively constant, regardless number patient. embryo, relation to its morphology, clearly lower when irregular blastomeres fragments were present perivitelline area. Other embryos, their had an identical development potential. Analysis results this demonstrates difficulty deter-mining potential all on basis morphological criteria.
