BACKGROUND In recent years, single blastocyst transfer combined with vitrification has been applied widely, which can maximize the cumulative pregnancy rate in per oocyte retrieval cycles and minimize the multiple pregnancy rate. Thus, the guarantee for these is the effectiveness of vitrified blastocyst. Studies has shown that AS of the blastocoel cavity prior to vitrification can reduce injuri...

BACKGROUND This study was done to test the hypothesis that intrauterine insemination (IUI) using a soft-tip catheter results in a higher live birth rate than IUI using a hard-tip catheter. METHODS Five hundred and forty patients were randomized into those inseminated with a soft-tip catheter (group 1, n = 267) and those inseminated with a hard-tip catheter (group 2, n = 269). Four patients we...

SETTING University-affiliated infertility clinic, between January 2001 and April 2007. PATIENT(S) Women undergoing a total of 6,500 IVF-intracytoplasmic sperm injection (ICSI) cycles.

Abstract Study question To evaluate whether preimplantation genetic testing for aneuploidy (PGT-A) can improve pregnancy and neonatal outcomes patients with limited good-quality embryos. Summary answer PGT-A failed to cumulative live birth rate or shorten time pregnancy, but optimized per transfer What is known already currently widely used screen the goal of improving rates. Remarkably, previo...
