Embryo transfer in days 2 to 4 following intracytoplasmic sperm injection: a prospective cohort study
Background: Improvement of assisted reproductive technique (ART) results in higher pregnancy rates from positive Beta HCG to take home baby statistics. Despite developments in culture media allowing blastocyst stage transfer, some centers apply second, third and sometimes fourth day post injection for embryo transfer. This study aimed to compare their reproductive outcomes. Methods : This p...
متن کاملGender incidence of intracytoplasmic morphologically selected sperm injection-derived embryos: a prospective randomized study.
The aim of this prospective randomized study was to determine if the use of intracytoplasmic morphologically selected sperm injection (IMSI) is associated with gender incidence. Couples who underwent IVF-preimplantation genetic screening (PGS) cycles, as a result of advanced maternal age, were randomly allocated into two groups: intracytoplasmic sperm injection (ICSI; n=80) or intracytoplasmic ...

OBJECTIVE To examine the effect of sperm morphology on embryo development at the chromosomal level. DESIGN Prospective study. SETTING Assisted fertilization center. PATIENT(S) Couples who underwent IVF-PGS cycle, as a result of advanced maternal age, were randomly allocated into two groups: intracytoplasmic sperm injection (ICSI; n = 60) or intracytoplasmic morphologically selected sperm ...
متن کاملPregnancy outcomes in women with repeated implantation failures after intracytoplasmic morphologically selected sperm injection (IMSI)
BACKGROUND The purpose of this study was to compare laboratory and clinical outcomes of intracytoplasmic morphologically selected sperm injection (IMSI) and conventional intracytoplasmic sperm injection (ICSI) in couples with repeated implantation failures. METHODS A total of 200 couples with at least two prior unsuccessful ICSI cycles were enrolled: 100 couples were submitted to IMSI and 100...
متن کاملP-219: Premature Progesterone Rise (PPR) At HCG Triggering Day Has No Correlation with ICSI Outcome: A Prospective Cohort Study
Background: The objective of this study is to evaluate the progesterone level (P Level) on the day of HCG triggering in GnRh agonist and antagonist protocols, and its correlation with clinical pregnancy rate and miscarriage rate. Premature luteinization during in vitro fertilization (IVF) was commonly happened before the introduction of GnRh analogues. High level of unwanted progesterone that i...
