First polar body morphology before ICSI is not related to embryo quality or pregnancy rate

7 Sept 2004

Abstract excerpt

BACKGROUND: The aim of this study was to analyse the relationship between the first polar body (1st PB) morphology and the fertilization rate, cleavage rate, embryo quality, pregnancy and implantation rate. METHODS: This was a retrospective study on 167 consecutive cycles undergoing assisted reproduction with ICSI. The 1st PB morphology was evaluated at the moment of ICSI in the 596 injected oocytes and it was...
