Active clinical trials for "Infertility"

Considering the importance assumed by follicular microenvironment for a proper oocyte development, this study is a prospective observational clinical trial which aims to evaluate whether the embryo blastocyst quality may be affected by different Myo-inositol (MI) and D-chiro-inositol (DCI) levels in the follicular fluid (FF) of the aspired oocytes. The study includes egg donors and egg receiving couples participating in the oocyte donation program. MI/DCI is calculated in FF and related with blastocyst grade.

The purpose of this project is to study the presence of expression differences - at RNA and protein level - of different members of the tachykinin family and kisspeptin and their receptors, between fertile women and infertile patients with different etiologies.

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.

Vitrification is a modern cryopreservation technique based on sudden cooling of reproductive cells to a temperature of -196 ° C in seconds that produces glass-like solidification of a solution without crystallization, but by extreme elevation in viscosity during freezing

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.
