The goal of this observational study is to discern if there is a relationship between timelapse imagery of human oocytes/embryos and PGT results. Embryos of patients that are undergoing PGT will be placed into a timelapse incubator. The data obtained by the timelapse incubator will be used in conjunction with the PGT data to determine any relationships.
It has been described that 11% of men with semen values within the normal range established by the World Health Organization (WHO) have sperm DNA fragmentation. This has been associated with a lower fertilization rate, lower embryo development and, therefore, lower reproductive success. Focusing on the study of the integrity of the male genome can provide us information to diagnose infertility in the couple. The use of conventional sperm selection methods such as swim-up or density gradients has been a great advance in the improvement of male fertility. However, these methods use centrifugation in their protocol, a procedure that has been associated with sperm DNA damage. The ZyMōt is a chip based on microfluidic properties that allows the recovery of spermatozoa with lower DNA fragmentation rate without centrifugation of the semen sample. This new sperm selection method maintains all the advantages of conventional techniques, but decreasing DNA fragmentation associates to sperm recoveries techniques eventually improving reproductive rates. This quality would be beneficial for patients with unexplained infertility, recurrent pregnancy loss or clinical varicocele, factors that have been associated with a higher index of DNA fragmentation. However up to date there is evidence-based data supporting such improvement. The main objective of the present project is to evaluate the ZyMōt as a new non-invasive sperm selection device and to see its impact on the euploidy rate, comparing it with a sperm selection technique that is routinely used in the clinic: swim-up. At the same time, the effect that this new chip may have on sperm and other reproductive variables will be analyzed clinically, and molecularly with immunohistochemical and transcriptomic analyses in order to observe the impact of SDF(sperm DNA fragmentation) at the molecular and genomic level in oocytes with low reparative potential oocytes.
TetraSOD® is a unique marine phytoplankton (Tetraselmis chuii) SOD-rich ingredient that is grown under patent-protected technology exclusively designed by the company Fitoplancton Marino, S.L. (Spain). In a previous pilot trial, the ability of TetraSOD® (dose: 250 mg/day) to improve semen characteristics in idiopathic infertile men after three months of treatment was assessed, revealing significant improvements in almost all of the analyzed parameters. In a further clinical trial close to finish (ClinicalTrials.gov Identifier: NCT04864314) using the same dose, such positive results have been tested again in a higher number of patients, and additional parameters have been included in order to gain insights into the sperm physiological changes that underpin the improvement in semen quality. In this new clinical trial, an intermediate dose (125 mg/day) is going to be tested in an attempt to determine a range of TetraSOD® dosage being clinically active for the treatment of male infertility.
In the current study, the adult infertile patients with clinical varicoceles will be included. the patients will undergo subinguinal varicocelectomy. The patients with spermatic cord lipoma detected at the time of surgery will be enrolled and divided into 2 groups( excision group, group A and preservation group (B). semen parameters will be compared in both group at 3 and 6 months after surgery
Study Aims: To evaluate the impact of oxidative and nitrosative stress, as well as DNA methylation, on male reproductive health. This is achieved by analyzing urinary biomarkers: 8-oxoGua, 8-oxoGuo, 8-oxodGuo, 3-nitrotyrosine (3-NO2Tyr), 5-methylcytidine (5-MeCyt), and cotinine in infertile and fertile males. Study Design: A prospective observational case-control study comparing infertile male patients (cases) from a reproductive sciences center with fertile male volunteers (controls) from a gynecology and obstetrics department. The study focuses on understanding the role of oxidative stress in male infertility and its implications for assisted reproductive techniques.
Prospective observational study on the quality of life of patients attending general urology, sexual medicine, reproductive medicine, functional urology, neuro-urology and uro-oncology clinics.The data relating to the clinical conditions (disease state, psychological and related to quality of life) of the patients belonging to the above-mentioned clinics will be collected in a specially designed database which will allow us to extract the data in a simple and safe way used for statistical analyses. in clinical research.
Infertility, defined as the inability to conceive after 12 months of regular unprotected intercourse, is estimated to affect 1 in 7 heterosexual couples. Semen analysis, carried out as per the detailed World Health Organisation (WHO) standards in an andrology laboratory, is the primary investigation for the male partner presenting to the fertility clinic and reports on multiple semen parameters. Hospital clinic attendance is required, which could be at a significant distance from the patient's home, to produce a sample at a given appointment time that is then analysed by the laboratory without delay, as the results are time sensitive. A formal report is produced after several weeks. This process was not sustainable during the Covid pandemic and these methods would be threatened by similar situations in the future. Despite semen analysis being an essential component of fertility work-up the WHO themselves state that the test does not distinguish between fertile and infertile men. In addition, it involves a significant cost to the national healthcare system. Therefore, a more efficient initial test of male fertility warrants consideration. Home semen analysis tests are a screening tool that provide a simplified, initial assessment. They are widely available to purchase in the UK, but are not currently issued to patients seen in NHS clinics. They have the potential to reduce time to diagnosis and reduce the cost to the healthcare provider. To investigate the clinical and cost effectiveness of using home semen analysis tests a randomised controlled trial (RCT) is needed comparing them to laboratory semen analysis (standard care). Before a fully-fledged national trial is planned in a UK setting, the investigators would like to undertake a feasibility study to answer, "Is it feasible to conduct a trial comparing home semen analysis tests with current standard practice for the initial assessment of men referred to the fertility clinic?"
By applying a "system medicine" approach, the project aims to identify new biomarkers and/or prognostic tools aimed at developing personalized strategies to prevent the onset of comorbidities in infertile men.
The hormonal environment (steroid, primarily) could have a very relevant pathophysiological role in association with SARS-CoV-2. That is, testosterone could play a relevant role in leaving male subjects more exposed to infection and more prone to developing severe complications following COVID-19 infection.
