Filter by:This is a randomized observational study. The main aim is to determine potential oocyte competence predictive mRNA expression profiles in the cumulus cells isolated form individual oocytes. In 2 patient cohorts: 1)GnRH Antagonist & hr-FSH with GnRH Agonist trigger, 2) Progesterone & hr-FSH with GnRH Agonist trigger.
Relevance of the research topic: At present, in the world, a kind of "plateau" in the efficiency of assisted reproductive technologies has been achieved, which ensures a birth rate of 30% per embryo transfer. At the same time, a relatively high (15-20%) and stable rate of miscarriages is preserved. Until now, no effective methods for assessing the potential of gametes and embryos, as well as human reproductive capabilities, have been offered. In these conditions, to increase the rate of births after IVF, clinicians have to increase the number of transferred embryos at a time, however, this leads to a sharp increase in complications of IVF, such as multiple pregnancy. In addition, until today, the clinical effectiveness of assessing the potential of endometrium using gene expression determination methods has not been shown. Therefore, to ensure the effectiveness and safety of infertility treatment, it is necessary to develop methods for predicting the potential of gametes and embryos, as well as human reproductive capabilities. For this purpose, the investigators assume to use Raman spectroscopy of the environment obtained from the objects of research, as well as fluorescent spectroscopy of endometrium. The objects of the research are gametes (spermatozoa) and embryos, used culture medium, endometrium. The subject of the study is the set of factors, that exists in the objects of research and their ability to determine the outcomes of infertility treatment.
The study is aimed to evaluate the effects of intraovarian injection of autologous Platelet-enriched Autologous Plasma on the outcomes of orthotopic transplantation of cryopreserved ovarian tissue.
In Vitro Fertilization (IVF) success is below 40%, with Embryo Transfer the leading cause of IVF failure. This clinical investigation aims to evaluate if the levels of an intrauterine biomarker dissolved in the uterine fluid (alone or as a complex biological marker) can predict the outcome of embryo transfer.
In the current study, the adult infertile patients with clinical varicoceles will be included. the patients will undergo subinguinal varicocelectomy. The patients with spermatic cord lipoma detected at the time of surgery will be enrolled and divided into 2 groups( excision group, group A and preservation group (B). semen parameters will be compared in both group at 3 and 6 months after surgery
The aim of this study is to assess the evaluate the effectiveness of vitrified donor semen in intrauterine insemination treatments.
The goal of this study is to determine if benchtop incubators improve the number of embryos making it to the blastocyst stage of development (about 4-6 days after fertilization) in people undergoing in vitro fertilization (IVF) treatment for their infertility. - Test the effectiveness of the benchtop incubator. - Determine if the number of embryos reaching the blastocyst stage of embryo development (the stage that the embryos are biopsied for PGT-A and frozen) is improved in the benchtop incubator compared to the box incubator. - Compare embryology outcomes between the two incubator types. - Investigate transfer and pregnancy outcomes. - Expand the knowledge surrounding the impact of the incubator on IVF outcomes. Patients will have their mature oocytes collected at the egg retrieval procedure split into two groups and randomized to be cultured in both incubator types.
Study Aims: To evaluate the impact of oxidative and nitrosative stress, as well as DNA methylation, on male reproductive health. This is achieved by analyzing urinary biomarkers: 8-oxoGua, 8-oxoGuo, 8-oxodGuo, 3-nitrotyrosine (3-NO2Tyr), 5-methylcytidine (5-MeCyt), and cotinine in infertile and fertile males. Study Design: A prospective observational case-control study comparing infertile male patients (cases) from a reproductive sciences center with fertile male volunteers (controls) from a gynecology and obstetrics department. The study focuses on understanding the role of oxidative stress in male infertility and its implications for assisted reproductive techniques.
A Prospective, Multicenter, Randomized, Pivotal Study of the May Health System in Transvaginal Ablation of Ovarian Tissue under Ultrasound Guidance in Women with Infertility due to Polycystic Ovary Syndrome
Oocyte quality is a basic parameter that affects embryo quality and therefore it influences the outcome of assisted reproduction. It has been suggested that oocyte quality is improved by the intake of vitamins and antioxidants. Ova-Max is a dietary supplement that consists of vitamins, minerals and antioxidants which improve women's oocytes by preventing oxidative stress. Specifically, Ovamax includes Chasteberry, Melatonin, Myo-Inositol, Folic Acid, Co-Enzyme Q10, Vitamin E, L-Arginine, Grape seed extract and Alpha-lipoic Acid. The purpose of this study is to evaluate the influence of Ova-max intake on oocyte quality in women undergoing In Vitro Fertilization. According to the research hypothesis the administration of Ova-Max for three months increases oocyte quality in women undergoing intracellular sperm injection after ovarian stimulation and oocyte retrieval.
