Assessing the Effect of Abstinence Period on Semen Parameters
InfertilityMaleThe goal of this study is to learn about the impact of abstinence periods on sperm quality in healthy males 20-45 years of age with no significant comorbidities who are able to produce a semen sample via masturbation. The main question it aims to answer is: • Do shorter abstinence periods result in improved semen quality? Participants will provide semen samples for analysis following abstinence periods of 7 days, 5 days, 2 days, 1 day, and 3 hours.
Sperm Selection Using Microfluidic Technology
InfertilityMaleThis clinical study has been organised to investigate whether microfluidic technology may be considered as a new procedure for routine sperm preparation during assisted reproduction. This is a technique that is already used in other centres. The Microfluidic Sperm Sorting (MSS) technology reduces the time of sample preparation while selects a sperm population with better motility and less DNA fragmentation as compared to routine procedures. This med-ical device is already CE marked. Having the intention to implement this technology in our department, we conduct this study to investigate whether the use of MSS has at least the same impact, if not better, on fertilization and embryo quality as compared to standard sperm selection procedures.
G-IVF and Sperm Parameters
InfertilityMaleThe aim of this study is to investigate if adding a fixed volume of a physiological solution to a freshly produced sperm sample will affect sperm characteristics.
Effect of COVID-19 on Platelet Mitochondrial Bioenergetic, Antioxidants and Oxidative Stress in...
InfertilityMale1 moreTo verify the hypothesis that infertility and the effect of SARS-CoV-2 on infertility may damage platelet mitochondrial bioenergetics and endogenous coenzyme Q10 levels in infertile men.
Single and Double DNA Strand Breaks in Males With Unexplained Infertility Attending Fertility Treatment...
InfertilityMaleThe aim of this study is to investigate the extent of double-stranded DNA damage in sperm in men with unexplained infertility.
The Impact of Lifestyle on Sperm Telomere Length and Telomerase Activity in Men Undergoing IVF Treatments...
Male InfertilityThis aim of this study is to determine the impact of lifestyle on telomere length and telomerase enzyme activity on sperm cells of men undergoing IVF treatments.
Characterization of Sperm Population Following Different Selection Procedures
Male InfertilityThe 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.
SpermQT Prospective Observational Trial
Male InfertilityThe 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.
Use of Testicular Spermatozoa in Non-azoospermic Patients

The Association of Gut Microbiota and Spermatogenic Dysfunction
InfertilityMale4 moreThis is a multicenter, case-control study that aims to investigate the relationship between microbiota and sperm quality via stool, blood, and urine microbiome, metabolomics, and collected clinical metadata. The results of the spermatogenic dysfunction, including aspermia, oligozoospermia, asthenozoospermia, and teratozoospermia, will be compared to normal basic semen analysis utilizing the World Health Organization (WHO) semen analysis procedure 5th edition.
