Pre-implantation genetic diagnosis (PGD) or screening (PGS) technology, has emerged and developed in the past few years, benefiting couples as it allows the selection and transfer of healthy embryos during IVF treatments. These techniques can be performed in oocytes (polar-body biopsy) or embryos (blastomere or trophectoderm biopsy). In this case report, we describe the first two live births to...

Background Infertility as one of most concerning topics in childbearing age mothers needs better managements with less complications and IVF can be assumed as an efficient method. This study aimed to compare pregnancy outcomes in fresh and frozen embryos transferred in IVF cycles. Methods In a retrospective study, 11201 patients underwent IVF cycles from 21st March 2013 to 20th March 2014 and...

To utilize propensity score matching (PSM), thereby creating similar cohorts, to evaluate the impact of ERA using embryos deemed euploid by pre-implantation genetic testing for aneuploidy (PGT-A). Retrospective cohort study autologous FET cycles between January 1st, 2014 and June 30th, 2019 at a single, university-affiliated infertility practice. Patients were included if they had transfer blas...

To determine the prevalence of premature luteinization in patients undergoing medicated frozen embryo transfer (FET) cycles where delayed start micronized progesterone is needed after last transvaginal ultrasound (TVUS) done. Retrospective cohort study FET at Mount Sinai Fertility (MSF), Canada between February 2019 and March 2020. At MSF, a protocol involves starting estradiol (4 mg PO/PV BID)...

Background: Aim of the study was to evaluate correlation endometrial morphology and sub vascularity with pregnancy rate in fresh frozen embryo transfer cycles.Methods: Prospective, non-randomized observational done on 76 women undergoing vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) treatment at a tertiary health care center. Woman tubal factor, male factor unexplained inferti...

Background: The aim of this prospective randomized clinical trial was to determine the optimal endometrial preparation protocol by comparing the clinical outcome of two methods of endometrial preparation in FET cycles, that is, oral estradiol and 17 β-estradiol transdermal patch. Materials and Methods: A total number of 90 patients were scheduled for FET. In the study group (n=45), 17-B estradi...

BACKGROUND GnRH agonist and antagonist were developed to control the premature release of LH surge. There is some difference between two protocols. OBJECTIVE We compared the outcome of frozen-thawed embryo transfer in infertile women who used GnRH agonist or antagonist protocol for previous COH cycle and evaluation of any adverse effect of GnRH antagonist on oocyte and embryo. MATERIALS AND...

STUDY QUESTION Have changes in assisted reproductive technology (ART) practice and outcomes occurred globally between 2003 and 2004? SUMMARY ANSWER Globally, ART practice has changed with an increasing prevalence of the use of ICSI rather than conventional IVF. In 2004, a small but increasing number of countries are incorporating single embryo transfer. There remain unacceptably high rates of...
