The increased use of vitrified blastocysts has encouraged the development of various criteria for selecting the embryo most likely to implant. Post-thaw assessment methods and timetables vary among investigators. We investigated the predictive value of well-defined measurements of human blastocyst re-expansion, following a fixed incubation period....
Purpose
Does thawing cleavage embryos and culturing them for transfer as blastocysts improve pregnancy and perinatal outcomes compared to transferring thawed blastocysts?Methods
Retrospective, observational cohort study performed at two assisted reproductive technology centers, 2014 to 2020. A total of 450 patients with 463 thawed embryo transfer c...
The superiority of day 5 blastocysts compared to day 6 blastocysts in fresh cycle transfers was previously demonstrated and attributed mainly to endometrial asynchrony. Data from frozen blastocysts transfers showed conflicting results, possibly due to heterogeneous patient population and embryo quality. The aim of this study was to compare clinical...
The objective was to evaluate the outcomes of in vitro maturation (IVM) cycles using gonadotropin releasing hormone agonist (GnRH-ag) triggering. A retrospective cohort of IVM cycles from January 2015 to December 2019 in a single university-affiliated centre was examined. Main outcome measures were: (i) IVM maturation rate; and (ii) IVM maturation...

Data were collected on all patients who...
Three-dimensional sonography enables assessment of uterine morphology. While the pattern of endometrial growth has been well described, little information is available on changes in endometrial and myometrial volume, area, and perimeters. We evaluated the ratio between myometrial and endometrial dimensions and its relation to endometrial thickness...
Aim:
To evaluate the number of oocytes retrieved as a criterion - when to use a "freeze-all" or low-dose "rescue human chorionic gonadotropin (hCG)" strategy.
Methods:
A retrospective study. Instead of the classic hCG trigger, an E2 level of ≥3,000 pg/mL was used to trigger ovulation with GnRH agonist. The decision whether to "freeze all" or per...
Human chorionic gonadotropin (hCG) is no longer a single, omnipotent ovulation triggering option. Gonadotropin releasing hormone (GnRH) agonist, initially presented as a substitute for hCG, has led to a new era of administering GnRH agonist followed by hCG triggering. According to this new concept, GnRH agonist enables successful ovum maturation, w...

Methods
A prospective cohort study was conducted. Whether or not a good quality embryo was transferred on day-3, poor quality (rejected) embryos were further cultured and followed. The clinical outcome of each embryo was assessed.
Results
A...
Background
IVF cycles which result in only one good quality embryo, and a second poor quality embryo present a dilemma when the decision involves transferring two embryos. The aim of this study was to evaluate whether a poor quality embryo has a negative effect on a good quality embryo when transferred along with a good quality embryo.

Most previous studies that calculated cumulative delivery rates following in vitro fertilization (IVF) treatments were limited in the number of cycles and the implementation of intracytoplasmic sperm injection (ICSI). Therefore, we assessed the yield of high-order consecutive IVF treatments (up to 14 consecutive cycles) with and without ICSI. Data...
Follow-up of the first cohort of 191 patients who underwent medical abortion in a tertiary medical center included postmenstruation transvaginal sonography (TVS), even in asymptomatic patients.

healthy women undergoing IVF were treated either with human menopausal gonadotrophin (HMG)...
Oocyte donation has become a common treatment modality for a large spectrum of infertility conditions. The purpose of this study was to assess the success rate of a shared egg donation programme, and to define the profile of a successful 'donor-recipient' couple in view of the limitations imposed by the shared programme. The results of all consecut...
Chronic intake of alcohol in high doses adversely affects almost all body systems, and no other toxic substance deserves more attention in view of the havoc it has wrought.
