View clinical trials related to Female Infertility.
Filter by:The present research project aims to study the DNAm mechanisms underlying the reduction of fertility due to the progressive depletion of oocyte quality. Specifically, our project aims to build an epigenetic clock for MGCs by using outcomes that are certainly related to female fertility. The validation of such findings will be carried out on peripheral blood in order to guarantee its non-invasiveness and allow for any clinical transferability. In order to identify a blood epigenetic signature able to predict female infertility, we planned to explore the problem from different points of view by conducting several studies in different settings.
The goal of this randomized controlled trial is to compare letrozole alone versus letrozole plus levothyroxine for ovulation induction in infertile women with both PCOS and subclinical hypothyroidism. The main questions it aims to answer are: Is letrozole plus levothyroxine superior to letrozole alone in achieving ovulation in these patients? Does combining levothyroxine with letrozole lead to higher pregnancy and live birth rates compared to letrozole alone? Participants will be randomized into two groups: Group 1 will receive letrozole only, starting at 2.5 mg daily from day 3 to 7 of the menstrual cycle. The dose will be increased up to 7.5 mg if no ovulation occurs, for a maximum treatment period of 6 months or until pregnancy is achieved. Group 2 will receive letrozole at the same doses as group 1 plus 25 mcg levothyroxine daily.
Female fertility may be affected by uterine fibroids, although this association has not been elucidated. This retrospective cohort study aims to evaluate the impact of fibroids on women fertility.
The aim of this study is to determine whether direct tubal flushing with oil-based contrast at HSG incorporated in the fertility work-up results in 10% more ongoing pregnancies and a shorter time to pregnancy, which will therefore be effective and cost-effective compared to delayed tubal flushing 6 months after fertility work-up is completed in women at low risk for tubal pathology.
Oxidative stress has been investigated as a key factor in the pathogenesis and progression of endometrioma. High follicular fluid ROS levels and serum can be related to negative IVF/ICSI outcomes in infertile women with endometrioma. Therefore, the use of antioxidants such as N-acetyl cysteine (NAC) may be reduced complications of endometrioma. To study this hypothesis, we designed a double-blind, randomized clinical trial study that aimed to determine the effect of N-acetyl cysteine (NAC) on stress oxidative factors and pregnancy outcomes in IVF/ICSI cycles in endometrioma patients.
The behaviour of the endometrium during its receptive phase is highly dependent on the endometrial cell type composition. Each cell type has its role in the endometrial preparation for the invading embryo. Alteration in the immune cells dialogue could be the main reason for unsuccessful implantation in certain patients. Immune cell homeostasis is often improved by intrauterine administration of autologous PBMC. There have been numerous reports on the positive effects of the intrauterine administration of autologous PBMC on the IVF outcomes (embryo implantation and ongoing pregnancy success). However, there is little data on the direct effect of the PBMC administration on the cell composition of the endometrium. This study will focus on the changes in the endometrial cell populations by PBMC treatment that could lead to IVF outcome improvement. The aim of this project is to analyze the effect of intrauterine administration of autologous PBMC on the endometrial cell populations and on the IVF outcome parameters (implantation and ongoing pregnancy success as IVF outcome variables).
Plastic products have been used ubiquitously in the modern world for many decades - for example as packaging materials, textile fibers or molded parts. The general use and especially the improper disposal lead to enormous environmental pollution almost everywhere on earth. Microplastics mainly originate from fragmentation of larger plastic objects or can be produced directly for the use in e.g. cosmetics or industrial dyes. Microplastics have already been detected in fresh- and seawater, soil, food, but also in human blood and urine. The accumulation of microplastics in ovarian and testicular tissue in humans has not yet been investigated.
Our study aims to describe the effect of the intrauterine adminstration of HCG versus the endometrial injury by pipelle on the ongoing pregnancy rate and the biochemical pregnancy rate in women with unexplained infertility undergoing ovulation induction. Also to describe the effect on the first trimester miscarriage rate, ectopic pregnancy rate, and multiple pregnancy.This study is an open-label, prospective, controlled study, multi-center study. The study participants' relevant medical records will be collected and reviewed after obtaining informed consent for the participants. The study materials that will be used will include blood tests, and ultrasound. The study will involve three study arms.
In the early stage, our team found that Acupuncture intervention in freeze-all IVF cycles can improve the clinical pregnancy rate. In order to further study the role of Acupuncture in improving the pregnancy outcome of IVF-ET in infertility. A randomized controlled clinical trial will be used in this study. 90 infertile patients are randomly divided into two groups. The control group will be treated with conventional modern medicine, and the treatment group will be treated with Acupuncture on the basis of conventional modern medicine. The intervention starts from the 5th day of the menstrual cycle and lasts to the day before IVF-ET. The number of oocytes, antral follicles, AMH, serum FSH, and clinical pregnancy rate will be observed to evaluate the effect of Acupuncture on the improvement of pregnancy outcome. In addition, all of the participants will be asked to complete the self-evaluation of the anxiety/depression scale on the 7th day of the menstrual cycle, before and after transplantation, to analyze the emotional changes of the subjects during the study. We observe the safety and health economic indicators of Acupuncture treatment, so as to improve the overall efficacy of TCM Combined Application in assisted reproductive technology in the future.
Synthetic products used in industrial, pharmaceutical, agro-alimentary or agricultural fields are found in our environment. Thus, humans could be simultaneously exposed to several of these pollutants. Furthermore, these environmental agents exert or could exert adverse actions on fertility, by altering gamete and embryo quality through endocrine disruptor effects or through increase in oxidative stress in gonads (cellular pathway known to be involved in several human reproductive pathologies). In this context, the objectives of the present project are to obtain descriptive and analytical data on woman and oocyte exposure to several environmental agents (bisphenols, ethynylestradiol and glyphosate). The relation between these pollutant measures in follicular fluid and urine (from women receiving follow-up of in vitro fertilization (IVF) protocol in the University hospital of Tours, France) and the oocyte quality, the IVF and pregnancy successes will be studied. Several oxidative stress biomarkers in blood and follicular fluid will be also measured for these women, who will complete a questionnaire on their lifestyles. Finally, thanks to in vitro approaches, the effects and the mechanisms of action (including oxidative stress) of these pollutants (alone or in cocktails) will be studied on granulosa cells from these patients.
