Active clinical trials for "Infertility"

The present study aims to determine which of the sperm selection techniques used in IVF (In Vitro Fertilization) laboratory leads to selection of the best/healthiest sperm population based on their morpho-functional parameters. Different procedures are currently used in our laboratory to select the sperm population that will be used to inseminate the oocytes: Density Gradient Centrifugation (DGC), DGC in combination with Magnetic Activated Sperm Sorting (MACS), and Microfluidic Sperm Sorting (MSS). The sperm cells selected by these techniques will be evaluated for specific morpho-functional features such as, motility, morphological abnormalities, and apoptotic status [phosphatidylserine translocation (early stages of apoptosis)] and DNA (Deoxyribonucleic Acid) fragmentation as an indicator of stages of apoptosis.

This study aims to validate the embryo culture medium analysis by nuclear magnetic resonance spectroscopy, as a faster and less-costly alternative to preimplantation genetic test for aneuploidy which could significantly enhance embryo selection and the success rate of assisted reproductive technologies.

EMBRYOx study aims to establish and validate the use of trophoblast organoids (embryoids) from trophoblast placental stem cells as a 3D research model in understanding further preimplantation embryo development in vitro. The organoids are capable of proliferation, differentiation, and implantation in a matrix, reproducing early human embryo development.

A low plasma level of mannose binding lectin (p-MBL) is associated with unexplained recurrent pregnancy loss (RPL), but it is not investigated if it is associated with unexplained reproductive failure in general, including recurrent implantation failure (RIF) after assisted reproductive technology (ART) (including IVF, ICSI and FET), recurrent pregnancy loss (RPL) after spontaneous conception, and RPL after ART.

The researchers aim to determine how baseline (preconceptional) and first-trimester uterine artery Doppler measurements affect obstetric complications in women undergoing high-quality blastocyst transfer and to determine the correlation between the two Doppler measurements.

Morphometric measurement of blastocyst diameter was taken on the day of trophoectoderm biopsy. PGT-A was done using NGS platform, followed by thawing and transfer of euploid blastocyts. Follow up of the Pregnancy and implantation rates is done and recorded to study the correlation between the diameter and reproductive outcomes of the blastocyst.

This study intends to explore the correlation between cervical microbiome, gut microbiome, transcriptome and pregnancy outcomes of frozen embryo transfer patients through a multicenter prospective observational study, and to explore the predictive value of microbiome on pregnancy outcome.

This is a prospective randomised study of the evaluation of the clinical IVF results after time lapse assisted embryo selection versus Non-invasive PGT-A assisted embryo selection in subfertile women.

The goal of the study is to validate the ability of the Epigenetic Sperm Quality Test (SpermQT) to assess a man's sperm quality and corresponding success of infertility treatments.

Multicenter prospective observational cohort study, comparing ongoing pregnancy rates in natural cycles for euploid embryo transfer in patients who present endometrial compaction at the time of the transfer versus those who have a stable or greater endometrial thickness with respect to the estrogenic phase.
