Active clinical trials for "Infertility"

Between March 2016 and March 2017, we performed a large retrospective, non-interventional, single-center cohort study and measured 25(OH)D3 plasma levels prior to ovarian stimulation in couples who underwent IVF/ICSI.And we analysed the correlation of vitamin D status and reproductive capacity .

Several studies indicate that Nitric Oxide (NO) plays an important role in the physiology of the reproductive system in mammals. It has been shown that NO affects sperm motility, it regulates the tyrosine phosphorylation of different sperm proteins, it enhances the sperm binding ability to the zona pellucida and it modulates the acrosome reaction. The enzyme responsible for NO synthesis, the Nitric Oxide Synthase (NOS), has also been identified in the oocytes, cumulus and corona cells, as well as in the oviduct. For these reasons, the NOS presence at the fertilization site could be a key element to determine the success of this process. Therefore, carrying out in vitro studies to better understand NO's role in the fertilization process, especially in human sperm capacitation, could improve the outcome of the Assisted Reproductive Techniques (ARTs) due to an improvement both in the diagnosis of infertility and in the prognosis of treatment success. This study is carried out in collaboration with the Animal Physiology Department from the Veterinary Faculty (University of Murcia, Spain) and it is funded by the European Commission under the Horizon 2020 Programme.

The overall objective of this study is to determine whether serum BPA and/or phthalate concentrations differ in fertile versus infertile men and women in Saskatchewan. The investigators will test the following hypothesis: Serum BPA and/or phthalate concentrations will be greater in women with unexplained infertility or PCOS compared to a control group Serum BPA and/or phthalate concentrations will be greater in men with male factor infertility compared to a control group

Women over 35 years old are likely to suffer from impaired oocyte repair capacity. Teratozoospermia is a condition reflects morphological affection of sperm. These spermatozoa would add an extra burden on the oocyte after ICSI. Whether selecting mature sperm by magnetic nanoparticle protocol would provide a more competent sperm to a likely affected oocyte would improve ICSI outcomes is the question of this research.

Using the cytoskeleton Stabilizer the Cytochalasin B would improve the outcome of oocyte vitrification.

Vienna Consensus has identified 10% damage rate after ICSI as a competency value. Despite the highest quality embryologists doing ICSI, degeneration sometimes occurs due to oocyte factors such as the fragile membrane, etc. Chaetoglobosin A serves to facilitate spindle or pronuclear transfer procedures helping to reduce the damage rate with no harm reported. Using Chaetoglobosin A during ICSI could serve to rescue some oocytes from the degeneration allowing for more chances of viable zygotes.

The aim of this study is to demonstrate that the KIDScore D3 may be used to identify those embryos on Day 3 that are most likely to form blastocysts.

In a prospective cohort study investigators will examine characteristics and clinical outcomes of treatment with ART in women with tubal factor infertility (TFI) with regard to seropositivity to antichlamydial antibodies.

The investigators conduct a follow up of our randomized controlled trial (RCT) to investigate the development of children born from In-vitro fertilization (IVF) and In-vitro maturation (IVM), in order to give strong evidence about the safety of IVM in women with high antral follicle count or especially polycystic ovary syndrome (PCOS).
