Spermotrend is a natural based product manufactured by Catalysis Laboratories. Its composition contains different essential elements for spermatogenesis: selenium, zinc and fructose. In addition, it contains L-arginine, natural precursor of nitric oxide that favors vasodilation, and pygeum africanum extract with antioxidant, antiinflammatory, antiandrogenic and antiproliferative action. Its main action resides in the control of oxidative damage to the tissues of the male reproductive system, as well as the control of correct spermatogenesis. Given that sperm quality can be altered by oxidative stress and that male infertility affects more and more people, the prevention and management of this deterioration becomes increasingly important. Therefore, to evaluate Spermotrend as a new therapy for male infertility, the investigators are going to study the safety and efficacy of this treatment in this clinical trial. RESEARCH HYPOTHESIS The treatment with Spermotrend improves the parameters of the spermatogenesis. GENERAL OBJECTIVES To evaluate the effectiveness and the safety level of the natural Spermotrend product in the treatment of male infertility. SPECIFIC OBJECTIVES - Evaluate the increase in sperm motility and concentration. - Identify the improvement in the seminal fluid volume. - Identify the positive changes in the sperm morphology. - Determine how to maintain the semen analysis in a normal range. - Describe the adverse effects. SECONDARY OBJECTIVES - Identify the improvement in urinary symptoms related with benign prostatic hyperplasia. - Identify the improvement in varicocele.
Azoospermia is defined as the complete absence of spermatozoa in the ejaculate. Two-thirds of azoospermic patients have non-obstructive azoospermia (NOA); the latter comprises up to 10% of infertile men overall. NOA is an untreatable testicular disorder associated with spermatogenic failure and is the most severe male infertility phenotype. Among the available surgical sperm retrieval techniques, microdissection testicular sperm extraction (micro-TESE) is the procedure of choice due to its high sperm retrieval success rates (SRR), minimal tissue extraction, and low complication rates. Even with the use of micro-TESE, the likelihood of retrieving sperm in patients with NOA remain suboptimal (40% to 60%). Hypogonadism is detected in approximately half of the patients with NOA. Given the role of intratesticular testosterone (ITT) levels for spermatogenesis, some studies have explored the clinical utility of testosterone optimization by medical therapy before sperm retrieval. Moreover, some investigators have hypothesized that the follicle-stimulating hormone (FSH) reset might increase the expression of FSH receptors and improve Sertoli cell function. Hormonal therapy with human chorionic gonadotropin (hCG) has been shown to improve ITT production and decrease FSH levels in patients with NOA. The investigators, therefore, designed an observational cohort study aiming to evaluate whether hormone stimulation with gonadotropins (e.g., hCG alone or combined with FSH) previous to micro-TESE increases sperm retrieval rates in hypogonadal infertile men with NOA, candidates for sperm retrieval. The investigators hypothesize that optimizing ITT production and resetting FSH levels may improve spermatogenesis and successful sperm recovery.
This 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.
This study investigates the effect of repetitive cycles of a Fasting Mimicking Diet (3x5 days in six months) on sperm quality in men
Varicocele is a major contributor in male infertility. The improvement of sperm parameters after varicocelectomy supports this contribution. The pathophysiological mechanisms of varicocele-induced male infertility are still under investigation. Cystatin C (Cys C) and endoglin are secreted glycoproteins that recently linked to several cellular changes common in varicocele like apoptosis and autophagy.
This study aims to eventually assess the usefulness of thermotaxis for sperm selection in routine clinical practice.
The microbiome plays an important role in health and in some unknown etiologies. Some previous studies have identified bacteria in semen as a potential factor in male infertility. More studies are needed to discover associations between microbiomes and semen quality. In this study, forty semen samples from donors candidates will be collected where clinical criteria for seminal quality (volume, concentration, motility and morphology) will be measured and bacterial communities examined. With the next-generation sequencing of gene technology and bioinformatic analysis, we can investigate the associations between bacterial communities and seminal quality. It would be interesting to know if the proportion of certain bacteria is significantly higher in samples of normal seminal quality or significantly higher in samples of low seminal quality. This study could contribute to the current understanding of certain etiologies of male fertility.
A non-pharmacological study, which examines the effect of lifestyle intervention on sperm quality among men in fertility treatment. The primary endpoint is to increase the total amount of motile sperm in male patients undergoing fertility treatment
This study examines the experience of people who have selected to use the at-home insemination Mosie Kit to understand the user's experience, the perceived safety and the efficiency. People who have recently purchased and voluntarily selected to use the Mosie Kit will be invited to complete a one-time online anonymous survey. The results of the survey will be analyzed to understand their experiences.
