Filter by: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.
Hepatitis C virus is commona viral infection. Direct-acting antiviral (DAA) oral drugs has been used in treatment of HCVs. the effect of these drugs on male infertility is still under investigation.
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 study aims to eventually assess the usefulness of thermotaxis for sperm selection in routine clinical practice.
Comparing second ejaculate and physiological ICSI (PICSI) as strategies for improvement of abnormal sperm DNA fragmentation in patients undergoing ICSI.
A total of 60 men (40 with a history of infertility and treatment with assisted reproduction and 20 infertile controls achieving conception naturally) will be asked to provide at least one semen sample each for conventional semen analysis including measurement of DNA-fragmentation and semen preparation with swim-up. The prepared semen sample will then analyzed by comprehensive microscopy analyses aiming at identifying distinct subpopulations of spermatozoa based on chromatin density and composition, mitochondrial and acrosome function and epigenetic markers. In addition, spermatozoa samples of selected individuals will be subjected to comprehensive analyses of the chromatin and RNA expression status using epigenomic approaches.
The purpose of this randomized clinical trial is to assess the effect of oral antioxidant administration to infertile men, by evaluating semen variables, sperm DFI and levels of ROS. Oral antioxidants or placebo will be given for 3 consecutive months. The study will recruit infertile men, who have one previous abnormal spermiogram, with at least one pathological variable (concentration, motility, morphology), according to WHO 2010 criteria. Participants will be recruited in the outpatient clinic of the Unit of Human Reproduction and of the Unit of Reproductive Endocrinology at the 1st Ob/Gyn Dept.
Semen analysis is the cornerstone for the valuation of the male partner in the infertile couples. This test has been standardized throughout the world through the World Health Organization (WHO) since the1970s by producing, editing, updating, and disseminating a semen analysis manual and guidelines.
Spermatozoa are vulnerable to lack of energy and oxidative stress as a result of elevated levels of reactive oxygen species. Therefore, it is essential that appropriate nutrients are available during maturation. This randomized, double-blind, placebo-controlled trial investigated the effect of 6 months supplementation with carnitines and other micronutrients on sperm quality in 104 subjects with oligo- and/or astheno- and/or teratozoospermia with or without varicocele. Semen analyses were done at the beginning and end of the treatment. In addition to main analyses, post-hoc analyses for age and body mass index (BMI) were carried out. Results were interpreted by dividing the population into two age and BMI classes.
