Filter by:This observational clinical study aims to determine the optimal timing of ovulation triggering in women aged 35 and above with poor ovarian reserve. For this purpose, cases undergoing ovarian stimulation for assisted reproductive treatment and planned final oocyte triggering will be evaluated in two separate groups: 1. **Experimental Group**: Final oocyte triggering will be performed when the follicle or follicles measure between 13-16 mm. 2. **Control Group**: Final oocyte triggering will be performed when the follicle or follicles measure greater than 17 mm. All triggers will be administered uniformly with 6500 units of recombinant hCG and 0,2 mg triptorelin injections. The primary outcome of the study will be the number of mature oocytes. Secondary outcomes will include fertilization rates, embryo counts, and implantation rates. Primary and secondary outcomes will be compared between the two groups.
The goal of this clinical trial is to learn if reducing the ejaculation abstinence time can improve the outcome of assisted reproductive technology. The main questions it aims to answer are: Does reducing the duration of ejaculation abstinence improve the clinical pregnancy rate for in vitro fertilization and intracytoplasmic sperm injection? Does reducing the duration of ejaculation abstinence improve embryo quality in in vitro fertilization and intracytoplasmic sperm injection？ Does reducing the duration of ejaculation abstinence affect pregnancy loss and live birth rates in in vitro fertilization and intracytoplasmic sperm injection? Researchers will compare less than 48 hours of abstinence time to more than 48 hours, to see if less than 48 hours of abstinence time improved in vitro fertilization outcomes Participants will: Control group abstinence for 3-7 days The experimental group ejaculated once on human chorionic gonadotropin trigger day Follow up their in vitro fertilization outcomes
The goal of this observational study is to learn about The purpose of this study was to compare the psychological differences between couples after IVF transplant failure and IVF pregnancy loss, including the differences in anxiety, depression, stress and post-traumatic stress between women and their spouses. The main question it aims to answer is: What are the psychological effects of IVF implantation failure and IVF pregnancy loss on women and the psychological differences between couples? Participants already taking IVF as part of their regular medical care will answer online survey questions about their joint pain for 1 years.
Despite technical advances in Medically Assisted Reproduction (AMP), the success of fertility treatments is sometimes limited by embryo implantation failure. The coordinated development of the embryo and the uterine endometrium requires close communication between the maternal tissue and the embryo. In in vitro fertilization (IVF), embryo transfer generally takes place between the 2nd (D2) and the 6th (D6) day following oocyte fertilization. Recent studies have shown the advantages of sequential transfer (transfer of an embryo on D2/D3 followed by the transfer of another embryo on D5/D6), with higher implantation and clinical pregnancy rate, fewer miscarriages, more live births, and yet no increase in multiple pregnancies. However, the American Society for Reproductive Medicine recommendations continue to prioritize the transfer of a single embryo for all patients aged under 38. To improve pregnancy rates for patients having a single embryo transferred, the study investigators wish to carry out on "blank" transfer, based on the principle of sequential transfer. The study investigators hypothesize that a culture medium, placed in the uterus before the time of embryo transfer, will modify immune tolerance. The study will test whether transferring the same culture medium in an equivalent quantity as during the real transfer into the uterus 2/3 days before the embryo transfer will improve tolerance to this foreign medium and, therefore, embryo implantation. The aim of this study is thus to evaluate the impact of a "blank" transfer with culture medium alone, on the results of frozen embryo transfers (FET) from IVF.
The goal of this clinical trial is to test whether sexual intercourse the night after embryo transfer affects thawed embryo implantation rates. Women undergoing one of their first four frozen embryo transfers with a good quality embryo will be randomly assigned to two groups. The study group is subjected to have intercourse without using a condom at the evening/night after the embryo transfer, while the control group will abstain from intercourse for the next 48 hours after the transfer. Researchers will compare the ongoing pregnancy rates between the intervention group and the control group.
This study compares hypnosis via virtual reality to sedation with commonly used intravenous anesthetic agents (propofol and remifentanil) during oocyte retrieval. The main objective of this prospective randomized controlled study will be a reduction of 50 percent of the doses of remifentanil and propofol administered during oocyte retrieval while maintaining satisfaction with the quality of care.
Retrospective study designed to evaluate outcomes in patients undergoing assisted reproduction. Some of them had thrombophilia, and part of them was treated with enoxaparin, started on the day of embryo transfer, and the other part not. Women without thrombophilia formed the control group.
The aim of the study is to ass wether or not the use of virtual reality during oocyte retrieval provides a better pain relief for patients, compared to a standard analgesic procedure.
This research was conducted to determine the effect of virtual reality-supported hypnofertility on fertility preparedness, stress and coping with stress in women having in vitro fertilization. At the end of research It has been determined that initiatives based on the hypnofertility philosophy increase the level of preparedness to fertility, decrease the stress level and provide effective coping with stress in women who had IVF treatment.
Oocyte retrieval procedure for in vitro fertilization is a source of anxiety for patients. Local anaesthesia or sedation are commonly used to manage many situations of anxiety, including the oocyte retrieval. However, this sedation should be as mild as possible in order to preserve oocytes. HappyMed Video Glasses are a recent medical device that allows the immersion of patients in films, cartoons or concerts. By distracting patients, this technology can reduce anxiety, discomfort and ultimately pain associated with care. This randomized monocentric trial compares audiovisual distraction versus usual care for the management of anxiety and pain related to oocyte retrieval. Hypothesis of this study is that the audiovisual distraction carried out with the HappyMed Video Glasses reduces the use of sedative drugs during oocyte retrieval while ensuring a better comfort and a faster walking ability.
