Filter by:This study aims to explore the potential correlation between decreased ovarian reserve and previous history of early miscarriage.
The goal of this randomized controlled trial is to assess the impact of ethanol sclerotherapy on ART cycle outcomes. The main questions it aims to answer are: 1. Does ethanol sclerotherapy before ART cycle has any impact on cumulative live birth rate in patients with endometrioma? 2. Does ethanol sclerotherapy improve chronic pelvic pain, dysmenorrhea, complications during oocyte retrieval, response to ovarian stimulation (number of mature oocytes retrieved), and pregnancy loss rates? Infertile patients with endometrioma between 4-10 cm who are scheduled for ART within 2 cycles will be randomized to ethanol sclerotherapy or no intervention.
This study aims to investigate if the use of oral micronized natural progesterone is not inferior to the use of subcutaneous antagonist in preventing LH peak in controlled ovarian stimulation.
to investigate the value of adding sildenafil citrate during endometrial preparation in patients undergoing frozen-thawed embryo transfer and its effect on endometrial thickness and pregnancy rates.
To compare the effectiveness and safety of Progesterone Primed Ovarian Stimulation protocol (PPOS) using Dydrogestrone vs GnRH Antagonist Protocol in patients with expected high ovarian response undergoing ICSI cycle
In 2% to 3% infertility women, myoma is the only factor relevant to their infertility. However, the effects of intramural myoma on fertility are controversial. For infertile women with intramural myoma (types IV, V, VI of FIGO system) of 4 to 6 cm diameter, it is not clear whether myomectomy could improve pregnancy outcomes, especially in women undergoing ART. Besides, rigorous clinical research is needed to explore the changes and relevant biomarkers of endometrial receptivity through multi-omics study in patients undergoing myomectomy and ART treatment. Method Intervention and follow-up: (1) For the control group, evaluation protocols such as salpingography and/or laparoscopic tubal fluxation should be implemented to identify disorders such as hydrosalpinx. (2) Imaging evaluation: all pelvic MRI were performed. Other options such as transvaginal ultrasound are not excluded, but won't replace MRI. Enhanced MRI or DWI may be considered, but are not always required. (3) Surgical intervention: laparoscopic myomectomy is preferred, and abdominal myomectomy is also acceptable. (4) IVF treatment: the IVF regimen should include detailed records of the downregulation plan, number of cycles, frozen or fresh blastocysts. Study endpoints (1) Primary study endpoint: Live birth rate after IVF. (2) Secondary study endpoints: Clinical pregnancy rate after IVF; Cumulative pregnancy rate after IVF; Biochemical pregnancy rate after IVF; Sustained pregnancy rate after IVF (≥20 weeks); Miscarriage rate after IVF; Cycles of IVF; Pregnancy-related complications; Perinatal maternal and neonatal complications. (3) Exploratory endpoints: The correlation between imaging index and assisted reproductive outcomes, including endometrial thickness, uterine volume, type of endometrial echo, uterine contraction; endometrial vascular index (VI), flow index (FI), tubular flow index (VFI); uterine artery pulsation index (PI), uterine artery resistance index (RI), systolic/diastolic blood pressure of uterine artery (S/D). The correlation between endometrial receptivity and assisted reproductive outcomes is analyzed based on transcriptomics, metabolomics, methylation and proteomics in samples from peripheral blood, endometrial biopsy, endometrial exfoliated cells, cervical exfoliated cells and myoma.
This study compares the use of virtual Reality versus the usual service protocol for the management of anxiety and pain related to In-Vitro fertilization (IVF) procedure
To assess the effect of reducing the oxygen concentration from 5% to 2% on Intracytoplasmic sperm injection (ICSI) outcome.
During assisted reproductive technology treatment, embryo selection is an important process that may affect the clinical pregnancy rate. Many assisted reproductive technology units over the world have tried different approaches to increase the clinical pregnancy rate. Conventionally, the morphology of the embryo is assessed by the embryologist with naked eyes only. Nowadays, artificial intelligence (AI) has been used to assist in morphological assessment of the embryo. Our pilot study showed that the AI-enhanced morphokinetic (MK) analysis increased the accuracy in embryo selection by ~9%, while the detection rate for abnormal chromosomes in embryo has also been increased by Raman spectroscopy (RS) analysis. The combined MK-RS analysis will be able to complete embryo assessment within 5-6 days after fertilization. This method needs shorter time and is at lower cost when compared to invasive preimplantation genetic testing for aneuploidies (PGT-A). In this study, we have combined the following non-invasive techniques to assist in embryo screening. 1. Using time-lapse imaging (i.e. images of embryo being taken every 10 minutes inside the incubator) with AI)-enhanced MK analysis to assess the entire morphological changes of the embryo. 2. As the embryo releases metabolites during its growth, the spent culture medium will be collected after culture of the embryo and then be used for RS analysis, which is a kind of metabolomics-based non-invasive PGT-A, for screening chromosomal abnormalities of the embryo. This study will include two phases. In Phase I, it is a retrospective part. We will collect data to train the convolutional neural network (CNN)-enhanced MK with RS method on embryo selection, leading to the integrated approach (MK-RS). In Phase II, it is a randomized controlled trial and participants will be randomised into 2 groups. For the experimental group, embryo selection will be based on the MK-RS method, whereas embryo selection for the control group will rely on the traditional embryo assessment results alone. Then we will assess the clinical pregnancy rate and evaluate the efficacy of our approach finally. Patients who receive in vitro fertilisation (IVF)/ intracytoplasmic sperm injection (ICSI) treatment from The Assisted Reproductive Technology (ART) Unit of The Chinese University of Hong Kong, Prince of Wales Hospital will be recruited.
The goal of this observational study is to understand the processes in the growing follicles development in more detail and to improve In Vitro Fertilisation (IVF) treatments. This involves measuring laboratory values in the blood, in the follicular fluid of the woman and in the sperm of the man as well as questionnaires concerning lifestyle factors. These values are then linked to the success of the fertility treatment to find out which of these values increase the success of the IVF treatment. Furthermore, the investigators want to investigate if there are differences between IVF treatments with or without hormonal stimulation of the ovaries.
