Filter by:Does period of abstinence impact progressive motility in oligoasthenoteratozoospermic (OATS) males? In the evaluation of male fertility, semen analysis is an important investigation. An abstinence between 2 and 7 days before a diagnostic semen analysis has been recommended by WHO (WHO 2010 guidelines), for the sake of standardization. The European Society of Human Reproduction and Embryology advises 3-4 days of abstinence before a semen analysis. The exact impact of abstinence period on sperm quality is a little complex and difficult to interpret. This study, 250 men with low sperm counts, motility and morphology will be recruited. The results will be analyzed to ascertain the impact of shorter abstinence period on semen quality
The investigators shall study the effect of Sinopharm vaccination on semen parameters and serum testosterone
This study aims to better understand the effects of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, virus that causes the coronavirus disease 2019 (COVID-19), on male fertility.
Donor sperm provides a viable option for patients with significant male factor infertility. However, since the source of sperm is not from the male partner, the psychological burden of these couples is more pronounced and complex than other patients.The purpose of this study is to investigate the stress faced by participants undergoing assisted reproduction with donor sperm and to further investigate its impact on pregnancy outcomes.
This study investigates the effect of repetitive cycles of a Fasting Mimicking Diet (3x5 days in six months) on sperm quality in men
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® 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 the present clinical trial, such positive effects will be tested again in a higher number of patients, and additional parameters will be included in order to gain insights into the sperm physiological changes that underpin the improvement in semen quality
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.
This study was planned to determine the effect of sexual counseling given to primary infertile couples in line with the PLISSIT model on sexual function and sexual satisfaction.
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.
