Filter by:Absolute asthenozoospermia is a rare condition in men with an occurrence frequency of 1/5000 and greatly affects fertility product. Previous studies have shown that the ovum can be fertilized with live but immotile sperm. However, the selection of live sperm for ICSI in immotile sperm samples is challenging for embryologists. Prominently, Pentoxyfilline (PTX) is a methylxanthine derivative, is an inhibitor of phosphodiesterase activity and increases intracellular cAMP levels, which play an important role in sperm motility. In recent years, many studies have demonstrated the effectiveness of PTX for the group of spermatozoa, sperm carrying severe abnormalities. In Vietnam, the application of PTX in ICSI has not yet been done in assisted reproductive centers. It is necessary to evaluate the effectiveness of PTX on ICSI treatment results in order to replace traditional methods and optimize treatment outcomes for patients.
This study is a comparison between the current standard practice of performing a transvaginal oocyte retrieval (TVOR) with paracervical block (PCB) and a relatively recently developed technology of virtual reality that is added to the above mentioned standard practice of TVOR + PCB. The aim of the study is to find out whether this newer technology has an advantage for the patient, in terms of anxiety and pain reduction or satisfaction.
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.
The main embryotoxicity quality controls are the mouse embryo test (MEA = Mouse Embryo Assay) and the human sperm survival test (HSSA = Human Sperm Survival Assay). The HSSA test measures the survival (or mobility) of human sperm after exposure to the tested consumable for a predetermined period of time and compares it to that of unexposed sperm. It would appear that the HSSA is comparable in terms of sensitivity to the MEA test for the detection of toxicity.
The aim of the study is to determine whether premedication with midazolam before oocyte aspiration in IVF procedures affects the amount of (oxidative) stress in women undergoing IVF and whether stress is also transmitted to the follicular fluid of aspirated follicles. The primary endpoint is the impact of stress during aspiration on the success of medically assisted fertilization (IVF / ICSI in the stimulated cycle).
This project wants to determinate whether there is a relationship between the N680S polymorphism genotype of the FSHR gene and the nature of the FSH used in controlled ovarian stimulation. It is a non-interventional, observational, cross-sectional and retrospective, national and multicenter study, in which a genetic test will be carried out to determine the genotype of the N680S polymorphism in samples of blood of patients who have undergone two cycles of controlled ovarian stimulation in the last 8 months.
This multicenter double-blinded placebo-controlled randomised trial aims to evaluate the effectiveness of vitamin D supplementation prior to IVF on the live birth rate in women with PCOS. Women with PCOS scheduled for IVF will be enrolled. Eligible participants will be randomised 1:1 to receive oral capsules of 4000IU vitamin D per day or placebo for around 12 weeks until the day of triggering.
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.
Deoxyribonucleic acid (DNA) damage of granulosa cells obtained during oocyte retrieval will be evaluated by comet assay in unexplained infertile patients undergoing in vitro fertilization (IVF) treatment. The oocytes will be graded by particular criteria. Fertilization, embryo quality, transfer rate, implantation, clinical pregnancy, pregnancy outcomes (gestational age at delivery, route of delivery, and birthweight etc.) will be recorded as well as demographic data. DNA damage of granulosa cells will be compared between unexplained infertile and control groups. The effect of DNA damage of granulosa cells on fertilization, quality of oocyte and embryo, implantation, and clinical pregnancy will be also evaluated.
The primary objective of this study is to evaluate the impact of a session of virtual reality (VR) with the objective of lowering the anxiety level on the clinical pregnancy rate following an In-vitro fertilisation (IVF) procedure. Indeed, anxiety in relation to infertility happens frequently and over time, can become stressful for our patients. This level of stress influences the effect of the infertility treatment. Reducing anxiety levels could promote the ability of the patients to face this stress and promote a greater chance of pregnancy in that context.
