Filter by:Randomized, controlled, double-blind, three-arm clinical trial in which 75 women will be randomized to treatment with metformin, 75 women to treatment with placebo and 50 women to the observation group. The medical intervention will last 24 weeks (6 months). Women with confirmed idiopathic infertility, in whom infertility factors have been excluded during full diagnostics, will be included in the study
The goal of this single center, non-blinded, randomized controlled clinical trial to comparison of pregnancy outcomes and perinatal outcomes in patients undergoing IVF treatment (including ICSI) with FET with letrozole-induce endothelial preparation protocol versus natural cycles, hormone replacement protocol. The main questions it aims to answer are: - To investigate whether letrozole-induce endothelial preparation is effective in improving the live birth rate and clinical pregnancy rate. - To explore its possible impact on clinically important indicators such as spontaneous abortion rate, implantation cycle cancellation rate, days of endothelial preparation, and number of visits to the clinic. The study subjects were randomized into groups starting at D1-D3 of the menstrual cycle. The study subjects were stratified according to whether their menstrual cycles were regular or not, and were divided into the following endothelial preparation regimens according to the pre-prepared stratified zoned randomized group numbers: (1) regular menstrual cycles (25-35 d): letrozole ovulation-promoting cycles, natural cycles, and hormone-replacement cycles; and (2) irregular menstrual cycles (<25 d or >35 d): letrozole ovulation-promoting cycles, hormone-replacement cycle.
This study is a single-center, randomized, controlled prospective study. Those patients with repeated implantation failure (RIF) who will recieve frozen thawed embryo transfer (FET) are enrolled in the study. To determine the effect of vaginal progesterone on the clinical pregnancy outcomes of RIF patients.
The goal of this clinical trial is to test the effect of a mindset management intervention on stress levels in women with infertility. The main question it aims to answer is: Can the Organic Conceptions approach decrease stress levels in women with infertility? Participants in both groups will be asked to complete three surveys at three time points. The intervention group will complete the Organic Conceptions program, while the control group will not complete an intervention. Researchers will compare the intervention group and control group to see if the Organic Conceptions mindset management program decreases stress levels in women with infertility.
The goal of this study is to compare the difference in clinical pregnancy, miscarriage and livebirth rate between day 6 euploid blastocyst transfer on the 6th and the 7th day of progesterone exposure in Hormonal Replacement Therapy (HRT) FET cycles. This prospective & randomized study will only include euploid day 6 blastocysts. This will be the first prospective study of euploid day 6 blastocysts thereby excluding aneuploidy as a cause of miscarriage and implantation failure. The point of randomization will occur on the day of progesterone commencement.
To evaluate whether single euploid embryo transfer in NC without routinely administered LPS is non-inferior to NC with routinely administered LPS.
This study aims to explore the potential correlation between decreased ovarian reserve and previous history of early miscarriage.
Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women of reproductive age and one of the leading causes of infertility. PCOS and obesity affect up to 12.5% - 48.3% Asian women, increase incidence of impaired glucose tolerance, type 2 diabetes and aggravate insulin resistance, cause ovulatory dysfunction and menstrual disorders, and negatively impact outcomes of Assited Reproductive Technology (ART), with higher miscarriage rate when receiving ART. Weight loss decrease insulin resistance and hyperandrogenism, improve ovulation rate and menstrual cycle, significantly higher conception and live birth rates. Weight loss prior to IVF procedures has been associated with significantly improved pregnancy rates (PR) and live birth rates. Furthermore, a decreased number of IVF cycles required to achieve a pregnancy has also been reported after weight loss interventions. Based on the principles of fetal programming, improving a lifestyle before conception might lead to improved longterm health of the offspring. Studies on the effect of anti-obesity medication combined with lifestyle changes on body weight and composition and metabolic - endocrine parameters and pregnancy rate in obese women diagnosed with PCOS are lacking. There is a growing need to develop pharmacologic interventions to improve metabolic function in women with polycystic ovary syndrome (PCOS).
Adverse childhood experiences can have powerful effects on health and quality of life in adulthood. Thus, having a history of childhood trauma, before the age of 18 (physical aggression, sexual abuse, death of a close person, etc.) significantly increases the risk of having cancer, cardiovascular disease, psychological damage , or earlier mortality. Validated scores allow the evaluation of the importance of adverse childhood experiences, in particular the ACE score (adverse childhood experiences) published by Felitti. Studies on the subject show a dose-response relationship between exposure to adverse childhood experiences and negative outcomes in terms of health and well-being. The physiopathological tracks to explain the occurrence of somatic pathologies in adulthood include the observation of a state of hyper-activation of the HPA axis that persists in adulthood; modulations of immunity, but also epigenetic modifications. Some data are available on the associations between childhood trauma and obstetric risks, with a significant increase in the risk of preterm delivery and fetal death in utero. Primary objective : 1a) To study the prevalence of adverse childhood experiences (ACE) in women consulting for the first time in an PMA service for the desire to become pregnant, and 1b) To study the association between adverse childhood experiences and infertility in adulthood, by comparing infertile women with nulliparous control women in the general population consulting for their classic gynecological follow-up.
The goal of this clinical trial is to investigate the impact of repeated antioxidant supplementation on blastocyst utilization and expansion rates in embryos under different oxygen concentrations. The study aims to answer the following main questions: - Does adding antioxidants every 12 hours to embryo culture media improve usable and expanded blastocyst utilization rates on days 5 and 6? - How are the O2 concentrations related to the effect of different methods of antioxidants supplementation on blastocysts utilization and expansion rates? Participants in this study are infertile couples undergoing in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) cycles. - Zygotes will be incubated at either 5% or 20% oxygen tension until the blastocyst stage. - Sibling zygotes will be divided into four groups: Group 1A and 1B: Antioxidants every 12 hours at either 5% or 20% O2 tension, respectively. Group 2A and 2B: Antioxidants only once at the beginning of embryo culture at either 5% or 20% O2 tension, respectively. Researchers will compare the four groups to determine if the repeated antioxidant supplementation of the culture media leads to improved blastocyst utilization and expansion rates compared to the baseline group.
