Filter by:It has been described that microgravity affects cellular and molecular structures. Cell membrane, cytoskeleton, cytoplasm and nucleus have been found to be sensible to gravitational changes. Alterations in the male and female reproductive systems have also been reported in mouse and other animals. The effects of microgravity on human reproductive cells remain unknown. The main objective of this experimental study is to investigate the effect of simulated microgravity in human male reproductive cells under in vitro conditions. Induced microgravity conditions will be obtained with a smaller single-engine aerobatic aircraft that can provide parabolic flights. The main parameters to be analyzed are: sperm motility, vitality, DNA fragmentation and apoptosis.
The proposed research aims to study the effects of antioxidant therapy, commonly used in male infertility treatment, on semen analysis. Patients presenting with male infertility, who are found to have abnormal semen analysis shall be recruited to this study. They will be asked to provide a sample of semen for routine semen analysis and advanced semen tests including sperm DNA fragmentation and sORP before starting with antioxidant therapy and after 3-month treatment with antioxidants. After completing the data analysis, we intend to publish the study in high impact perr reviewed journals and present it in international conferences.
The main purpose of the study is to assess to which degree a series of sperm parameters known to be associated with fertilization and implantation potential in artificial reproductive technology (ART) differ in consecutive sperm samples produced after 2-7 days and 2 hours of sexual abstinence in males from couples referring for ART treatment.
The purpose of this study is to determine if the pre-operative levels of sex-hormones can be used to identify the varicocele patients who can expect improvements in their semen parameters following varicocelectomy.
