Filter by:The aim of this observational study is to better understand the role and involvement of the regulatory elements of the CFTR gene, with the aim of better describing the 3D organisation of chromatin at the CFTR locus in epididymal cells in patients with male infertility of any kind, or with cystic fibrosis or bilateral agenesis of the vas deferens, requiring scheduled surgery. The main questions it aims to answer are: - to better characterise this 3D organisation of the CFTR locus, the study of regulatory elements in primary epididymal cells is the most relevant and realistic model. - to gain a better understanding of the regulation of the CFTR gene in epididymal cells in order to gain a better understanding of the pathology of male infertility caused by bilateral agenesis of the vas deferens, a symptom and also a borderline form of cystic fibrosis. Participants will Epididymal samples will be taken by a urologist for the AMP department during the planned surgery. The rest of the samples taken will be recovered for research purposes, with the aim of recovering the epididymal cells contained in the sample. This is in no way an additional procedure and will have no impact on the patient's health..
Approximately 30% of the factors that cause male infertility are due to idiopathic causes. Increased reactive oxygen species (ROS) due to many known and unknown factors cause male infertility by affecting spermatogenesis and sperm maturation. In this study, the effects of physical activity and antioxidant food supplementation on seminal antioxidant capacity, sperm DNA fragmentation index, sperm chromatin quality and sperm parameters were investigated in infertile cases.
Organoid Model to unravel Klinefelter Syndrome infertility Klinefelter Syndrome (KS) is characterized by the presence of an extra chromosome X in male (47,XXY), it is the most frequent genetic cause of azoospermia in adult men. The investigators will isolate and expand spermatogonial cells from KS patients, then using an organoid model investigators will compare the behavior of these Spermatogonia from KS patients when interacting with four combinations of somatic cell types incorporated in the Extra Cellular Matrix hydrogel.
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.
Male factor infertility is a leading cause of primary and secondary infertility. Poor sperm quality is defined as having an abnormal semen analysis. There are now options to assess sperm quality with at-home sperm analysis kits, including an FDA approved Yo Sperm kit (https://yospermtest.com/) which analyzes the motile sperm concentration [concentration (millions / ml) x motility (Percentage motile)] and sperm quality (YO Score) which compares your results to laboratory standards and to other men who have fathered children. The effects of supplements (vitamins, minerals, and anti-oxidants) on improving sperm quality are still debated. Taking additional supplements to improve sperm quality represent a modifiable risk-factor that would be an easy intervention for patients struggling with male factor infertility. The life cycle of sperm production is estimated at 3 months, so any intervention would require a 3 month course to see its full effect. The investigators hypothesize that a 90 day course of the "Power Prenatal for Sperm", a male fertility supplement by Bird&Be (https://birdandbe.com/the-power-prenatal-for-sperm) will improve sperm quality (YO Score) after taking the supplements.
The goal of this clinical trial is to investigate the impact of repeated antioxidant supplementation on blastocyst utilization and expansion rates in embryos under different oxygen concentrations. The study aims to answer the following main questions: - Does adding antioxidants every 12 hours to embryo culture media improve usable and expanded blastocyst utilization rates on days 5 and 6? - How are the O2 concentrations related to the effect of different methods of antioxidants supplementation on blastocysts utilization and expansion rates? Participants in this study are infertile couples undergoing in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) cycles. - Zygotes will be incubated at either 5% or 20% oxygen tension until the blastocyst stage. - Sibling zygotes will be divided into four groups: Group 1A and 1B: Antioxidants every 12 hours at either 5% or 20% O2 tension, respectively. Group 2A and 2B: Antioxidants only once at the beginning of embryo culture at either 5% or 20% O2 tension, respectively. Researchers will compare the four groups to determine if the repeated antioxidant supplementation of the culture media leads to improved blastocyst utilization and expansion rates compared to the baseline group.
This is a study of infertility which often occurs in men with spinal cord injury. Most men with spinal cord injury have a normal sperm count but abnormally low sperm motility - which means that the sperm does not swim well. This study will determine if a medicine given by mouth will improve sperm motility in men with spinal cord injuries. The medicine is called probenecid.
Sperm DNA fragmentation (SDF) serves as a marker for chromatin and DNA damage in sperm. Assessing sperm DNA integrity is crucial in male fertility evaluation since high levels of SDF are associated with a greater number of adverse reproductive outcomes, including an increased risk of miscarriage and birth defects. Recent research suggests that advanced paternal age (APA) may lead to DNA damage in sperm, however the precise age at which this risk becomes apparent has not yet been clearly defined, necessitating the identification of the point in time at which high SDF levels occur. With the help of this knowledge, male infertility can be diagnosed with greater accuracy, and infertile couples can receive appropriate care.
Normal embryonic development relies on the correct transmission of genetic information, and sperm DNA plays a crucial part in this process. Causes of poor sperm DNA integrity include unhealthy lifestyles such as smoking and exposure to gonadotoxins, as well as, obesity, varicoceles, infections, advanced paternal age and systemic disorders. An increase in DNA fragmentation in sperm has been linked to lower fertilisation rate, poorer quality embryos, lower pregnancy rate, and high miscarriages rate. The best way for sperm selection and processing in assisted reproductive technologies (ART) should be noninvasive and cost-effective. It should also make it possible to identify high-quality spermatozoa and produce more favorable results in terms of pregnancy and live birth rates.7 Meanwhile, the microfluidic sperm separation technology is a less expensive and less invasive alternative. This method allows for the selection of motile sperm that have a normal morphology, low levels of reactive oxygen species (ROS), and low DFI
Worldwide infertility affects about 15 % of reproductive-age couples. In many cases, infertility can't be treated, new treatment options with promising value were involved in the recent clinical trials.
