Filter by:The investigators conduct a long-term follow-up at five years on offspring born from our randomized controlled trial (RCT) to investigate whether or not there is any difference in developmental outcomes in children born after capacitation IVM (CAPA IVM) compared with conventional IVF in order to give strong evidence about the safety of IVM in women with high antral follicle count.
The aim of this randomized controlled trial is to examine whether single blastocyst transfer in the first cycle after oocyte retrieval (immediate) is non-inferior to single blastocyst transfer in a subsequent cycle (postponed) in stimulated or programmed cycle frozen embryo transfer (FET). The primary outcome is live birth rate.
This randomized clinical trial aims to assess the comparative effectiveness of two distinct endometrial preparation protocols for frozen embryo transfer (FET) among women with adenomyosis undergoing IVF/ICSI. Specifically, it seeks to address the following key questions: 1. Does the protocol involving the combination of GnRH agonist and letrozole for down regulation with exogenous steroids (GnRHa+AI - AC) result in a higher live birth rate compared to the use of exogenous steroids alone (AC) in women with adenomyosis undergoing frozen embryo transfer? 2. What are the common side effects of the GnRHa+AI - AC regimen? Eligible participants will undergo screening before endometrial preparation for FET, following which they will be randomly assigned to one of two groups: GnRHa+AI - AC or AC. In the GnRHa+AI - AC group, participants will be pre-treated with GnRH agonist and letrozole two months before endometrial preparation. After this period, participants will return for endometrial preparation, and any side effects resulting from the down regulation will be evaluated. In contrast, the AC group will receive standard treatment.
This study aims to evaluate the efficacy of the progestin-primed ovary stimulation (PPOS) protocol compared to the standard GnRH antagonist (GnRH_ant) protocol across successive stages in a controlled ovarian stimulation (COS) and ICSI procedure.
In order to get optimal pregnancy rates after frozen embryo transfer (FET), the embryo stage and endometrium should be synchronized. Endometrial preparation is done by either natural, artificial (Hormonal replacement therapy HRT) , modified natural methods or mild ovarian stimulation. HRT cycle has a better schedualization however, there are some reports about higher rates of miscarriage, pregnancy induced hypertension (PIH) and preeclampsia (PET) in HRT cycles. A recent study has found that incorporation of the aromatase inhibitor (letrozole) to HRT cycles was associated with better FET outcomes in comparison to hormonal replacement therapy cycles alone. Meanwhile, mild ovarian stimulation protocol can be done either by oral drugs like letrozole or by letrozole plus gonadotropins . So this study aims to compare the reproductive outcomes in two endometrial preparation protocols for frozen embryo transfer cycles; letrozole mild ovarian stimulation versus HRT plus letrozole incorporation.
This pivotal study is an observational, prospective assessment, multi-center, databank based, clinical study aimed to evaluate the performance of CHLOE™ algorithm in prediction of blastocyst formation. Day 3 morphological grading will be performed by three clinical embryologists (hereafter "Assessors"), who will use standard embryo grading assessment techniques and will be blinded to the CHLOE™ information and to the actual blastocyte status (Yes/No). Five independent embryologists (hereafter "Panelists") who will be masked to imaging data, to actual blastocyst status, and to each other evaluations will be provided with the morphological grading information performed earlier by the 3 assessors and with the age of subject or egg donor. All data will be presented to Panelists as full cohorts of embryos for each mother. Then they will provide their prediction on blastocyst status of each embryo twice: once the prediction will be based on morphology only and once on morphology plus CHLOE™ assigned score ("High", "Medium+", "Medium-", or "Low"). The two assessments will be done with a washout period of at least 2 weeks and no information will be provided to link the two assessments.
Various to-be-discard material from IVF treatment cycle will be collect and examined, aiming to identify potential reasons of successful outcome or cycle failure.
A multi-center randomized clinical trial is proposed to study the effectiveness of the advanced decision support tool Opt-IVF for ALL PROTOCOLS in reducing medication, testing, and improving outcomes.
To compare the effects of Duphaston compared to GnRH agonist and antagonist on the prevention of premature LH surge and quality of retrieved oocytes and embryos in women undergoing intra-cytoplasmic sperm injection.
This study aims to explore the potential correlation between decreased ovarian reserve and previous history of early miscarriage.
