NCT06150703
The development of stimulation protocols for in vitro fertilisation (IVF) has led to a paradox. It has now been established that obtaining a large number of oocytes is a key to success, but that it is also a risk factor for embryo transfer failure after puncture (disruption of endometrial receptivity due to luteal insufficiency) and a risk factor for complications such as ovarian hyperstimulation syndrome (OHSS).
NCT06604091
Previous studies have shown that compared with infertile women without adenomyosis, the clinical pregnancy rate, live birth rate and continuous pregnancy rate of women with adenomyosis significantly reduce, and the abortion rate obviously increased. However, these studies lack a definite classification of adenomyosis, so the true effect of adenomyosis with different severity on pregnancy outcomes are not clear. Our research team intends to collect clinical data of infertility patients with adenomyosis receiving IVF and the detailed classification of adenomyosis according to MUSA criteria. Finally, we can have an objective recognition of adenomyosis on pregnancy outcomes, which also bring benefits to evidence-based clinical practice.
NCT06367985
Capacitation in-vitro maturation (CAPA-IVM) has recently been advanced in culturing oocytes from the germinal vesicle (GV) stage following mild or no controlled ovarian stimulation. Recent research suggested that O2 concentration may significantly regulate oocyte maturation and early embryo development through hypoxia-inducible factor (HIF). Nonetheless, it has been challenging to create the environmental culture conditions for addressing the optimal number of oocytes and the highest possibility of embryo development since consensus on the oxygen (O2) concentration index in the IVM culture environment has not been reached. Based on the outcomes of atmospheric O2 concentration (20%) and low O2 concentration (5%) during CAPA-IVM culture in mice, it has been hypothesized that a 5% O2 was the optimal culture condition for the pre-IVM step. A 20% O2 was more suitable for the IVM culture step. Therefore, this study is designed to enhance the CAPA-IVM culture system, improving treatment efficiency and providing various benefits for patients undergoing assisted reproductive technology.
NCT07007416
This prospective observational study aimed to evaluate the effects of supraphysiological estradiol (E2) levels, induced by gonadotropin therapy during IVF, on cardiac electrophysiological parameters. Sixty-two women aged 18-40 undergoing IVF treatment at Konya City Hospital between December 2024 and January 2025 were included. ECG recordings were performed twice: once before gonadotropin stimulation and again on the day of hCG administration, when peak E2 levels were expected. Routine blood tests and hormone levels were also evaluated. Patients with obesity, cardiovascular disease, chronic illness, or medication use were excluded. After treatment, significant increases were observed in PR interval, J-Tpeak, QTc, and Tp-e values. E2 changes showed a moderate negative correlation with QTc and a low positive correlation with J-Tpeak. The results suggest that elevated E2 levels during IVF may affect cardiac electrophysiology, highlighting the need for careful monitoring in women with cardiac risk factors.
NCT06990685
With the decreasing of birth rate and population in our country, population problem has become a long-term and strategic problem. In addition to the decrease in the number of women of childbearing age and the impact of unmarried women, the increase in the incidence of reproductive disorders and the delay of marriage and childbearing are also important factors leading to the continuous decline of the birth population in China. Among them, ovarian aging is a key factor causing female fertility difficulties. Therefore, establishing an effective prevention and treatment strategy for ovarian aging is of great significance for improving female reproductive health and serving the national population strategy. Recently, several supplements have been found to promote folliculogenesis and improve oocyte quality. However, to date, there is no approved therapeutic agent for the treatment of ovarian aging. Therefore, it is urgent to develop effective strategies for the prevention and treatment of ovarian aging. Salidroside is the main active component of Chinese medicine Rhodiola, and its content is highest in the root of rhodiola, which is also the main medicinal part. The main efficacy of salidroside in traditional Chinese medicine is to benefit qi, promote blood circulation, unblock pulse and relieve asthma. At the same time, in basic research, more and more experiments have shown that salidroside has a variety of pharmacological properties, including anti-hypoxia, anti-fatigue and anti-aging effects, anti-cancer, anti-inflammatory, anti-oxidation, antiviral and so on. These pharmacological effects suggest that salidroside may be an effective drug for the prevention and treatment of atherosclerosis, Parkinson's disease, Alzheimer's disease, pneumonia and other diseases. In terms of aging, it has been confirmed that salidroside supplementation can prolong the life span of pseudogill oryzias zhan and rescue premature aging of human skin fibroblasts, etc., which further confirms. The aim of this study is to investigate the efficacy of salidroside as an adjuvant drug in improving the pregnancy outcomes of fresh embryo transfer in high childbearing age patients with poor ovarian response by comparing the pregnancy outcomes of fresh embryo transfer between salidroside group and blank control group. This pragmatic clinical study is expected to improve pregnancy outcomes of fresh embryo transfer cycles in women of advanced childbearing age with poor ovarian response.
NCT06741748
The goal of this clinical trial is to evaluate whether the direct warming method for frozen embryo transfers (FET) can improve live birth and pregnancy outcomes in women aged 18-45 undergoing IVF treatments. The main questions it aims to answer are: * Does the direct warming method achieve a similar or higher clinical success rate for FET compared to the conventional multi-step method? * Is the direct warming method more cost-effective than the conventional method? Researchers will compare the direct warming method to the conventional multi-step method to see if the former leads to better pregnancy outcomes and reduced procedural time. Participants will: * Undergo either the one-step or conventional embryo thawing procedure. * Complete standard clinical follow-ups for pregnancy, including ultrasound scans and pregnancy tests.
NCT06261671
One of the most sensible factors in IVF culture conditions is the susceptibility of gametes and embryos to an induced increase in reactive oxidative species (ROS) caused by the artificial environment. This study aims to evaluate the impact of using antioxidant-supplemented media during culture to evaluate embryo ploidy rates in a prospective randomized trial using sibling oocytes.
NCT06624683

NCT06521957
The goal of this clinical trial is to learn if Cognitive Behavioral Therapy (CBT) can improve psychological, neurological, and hormonal aspects in women undergoing In Vitro Fertilization (IVF). The main questions it aims to answer are: * Is CBT effective in improving psychological aspects (anxiety, depression, and coping mechanism) in women undergoing IVF? * Is CBT effective in improving neuroendocrine aspects (cortisol levels, neuroepinephrine levels, free trioodothyronine levels) in women underoing IVF? Researchers will compare CBT to no intervention to see if CBT is effective in improving psychoneuroendocrine aspects.
NCT03758833
In vitro fertilization (IVF) techniques have been improving performance recently and, nowadays, provide a live birth rate of around 25%. The success of IVF techniques is dependent upon maximum efficiency at each stage of treatment, and, at the same time, high success rates with a low risk of complications. Multiple pregnancies are one of the most important adverse event of IVF techniques. In this sense, the use of elective single embryo transfer (SET) has become an option for patients with good prognosis compared to the transfer of multiple embryos, and it is recommended in order to reduce the risk of multiple pregnancies and their consequences. On the other hand, it is known that embryonic quality is a crucial step for the success of IVF techniques and the efficiency of this process is linked to the decrease in the number of embryos to be transferred. Usually, embryo selection is based on morphological and developmental criteria. However, recently, it has been demonstrated that the blastocyst biopsy associated with the chromosomal / genetic screening may be a predictor of the chances of implantation. The investigators group demonstrated the feasibility of performing SET sequentially, promoting satisfactory gestation rates and safety for the mother and baby regarding multiple gestation for patients with good prognosis. Based on these principles, the investigators raised the hypothesis that SET associated with preimplantation genetic diagnosis (PGD) by next-generation sequencing (NGS) for patients with good prognosis can improve the success rates of IVF cycles and, at the same time, avoid multiple pregnancies, as well as maternal-fetal and neonatal risks resulting from this condition. To test this hypothesis, the aim of this study is to compare the results of IVF treatments in patients receiving SET (SET group), SET associated with genetic evaluation by NGS (group NGS + SET), elective transference of two embryos (DET group) and DET associated with genetic evaluation by NGS (NGS + DET). In case of non-pregnancy on the first transfer, there will be subsequent transfers until the remaining embryos are exhausted or the patient reaches the gestation. The primary endpoint will be the cumulative pregnancy rate per treatment cycle and this approach will allow to confirm or not the hypothesis that genetic analysis is effective in improving the embryo selection process and associated with SET will increase clinical gestation rates and decrease rates of multiple gestations and miscarriages.

NCT05402605
Poor ovarian response (POR) remains one of the significant challenges of Assisted Reproductive Technology (ART). Facing difficulties related to clinical practice, optimizing the embryo culture process is necessary to improve the embryo number and quality in this group of patients. Potential techniques mentioned in the current literature include follicular size at trigger, dual trigger, artificial oocyte activation (AOA), blastocyst transfer, and the role of preimplantation genetic testing for aneuploidy (PGT-A). AOA is currently expected to improve treatment outcomes in poor ovarian responders with the potential for clinical efficacy. However, this issue has not been evaluated before.
