Filter by:Infertility was reported in approximately 15% of all heterozygous couples, with male factor accounting for nearly half the cases. This typically occurs due to low sperm production, sperm dysfunction, and sperm delivery obstruction. Etiology of male infertility can be attributed to many factors including acute or chronic illness, accidents, and lifestyle choices.
The overall objective of the proposed study is to enhance early detection of male factor infertility and reduce cost and morbidity associated with delayed diagnosis through development of a universal screening model based on home semen testing. The advent of inexpensive and accurate home semen testing has enabled a potential paradigm shift in the approach to male fertility evaluation. The investigator's central hypothesis is that universal home semen testing prior to attempts to conceive is easy for participants and can lead to reduced fertility-related anxiety and early detection of male factor infertility, thereby expediting evaluation and treatment for the couple while minimizing unnecessary cost and morbidity. This study is specifically designed to assess the feasibility and utility of home semen testing for couples who are beginning attempts to conceive. First, the investigator will assess participants' ability to complete the home semen testing, ease of use, and obstacles encountered in doing so. Second, the investigator will examine the impact of home semen testing in fertility-related quality of life among couples beginning attempts to conceive, as well as ability of home semen testing to increase the diagnosis and treatment of male infertility in these couples.
Investigate the effect of intratesticular injection of autologous platelet rich plasma (PRP) on sperm retrieval rates and IVF outcomes in infertile men who already underwent a negative sperm retrieval. Currently, there is no alternative treatment after failed TESE. Prior series suggest that intratesticular PRP injections may improve TESE outcomes. We hope to determine whether PRP is an effective treatment for this patient population.
Testicular dysgenesis syndrome (TDS) is known to cause epigenetic abnormalities in spermatozoa. Anogenital distance (AGD) is considered to be a suitable clinical marker of TDS, but the direct link between AGD and epigenetic abnormalities is still missing. Infertile men (n=10) presenting with shortened AGD and a control group of normal semen donors (n=10) with normal AGD will then be asked to provide one semen sample each. Using a flow cytometer and sorter (FACS) their spermatozoa will be sorted into populations of spermatozoa with/without DNA fragmentation or with/without chromatin decondensation. These sorted populations of spermatozoa will then be examined for differences in epigenetic imprinting differences using whole genome expression analysis. Whereas the sorting of spermatozoa will be carried out in Basel, the epigenetic analysis will be carried at the University of Geneva.
To 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.
Male factor infertility is a leading cause of primary and secondary infertility. Poor sperm quality is defined as having an abnormal semen analysis [WHO 2020 - https://www.who.int/publications/i/item/9789240030787]. The effects of supplements (vitamins, minerals, and anti-oxidants) on improving sperm quality are still debated (https://pubmed.ncbi.nlm.nih.gov/30462179). 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 based on semen analysis results prior to, and after taking the supplements.
The purpose of this study is to determine whether Punalpin, an antioxidant, has a positive impact on DNA fragmentation in spermatozoa in male fertility patients with increased amount of DNA fragmentation in their spermatozoa. Secondary purpose is to investigate whether there is any positive effect on the subsequent pregnancy rates from the fertility treatment.
The 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.
To assess whether the presence of Cytomegalovirus (CMV) Immunoglobulin G (IGG) antibodies in semen is a reliable predictor of male subfertility or infertility.
This study aims to evaluate the safety and efficacy of Bu Shen Yi Jing (BSYJ) Pill , a type of traditional Chinese medicine, in improving male subfertility and semen parameters.
