    • AR CAG repeat length is not associated with serum gonadal steroids and lipid levels in healthy men 

      Goutou, M.; Sakka, C.; Stakias, N.; Stefanidis, I.; Koukoulis, G. N. (2009)
      P>Cardiovascular risk factors seem to be affected by androgens, which exert their action through the androgen receptor (AR). Androgenic action correlates inversely with a polymorphic CAG repeat region in the AR gene encoding ...

    • The BMI of men and not sperm parameters impact on embryo quality and the IVF outcome 

      Anifandis, G.; Dafopoulos, K.; Messini, C. I.; Polyzos, N.; Messinis, I. E. (2013)
      It has been reported that increased body mass index (BMI) of men influences fecundity but it is not clear if it impacts on sperm parameters. Whether or not BMI of men influence sperm parameters and subsequently in vitro ...

    • Dexamethasone reduces acrosin activity of ram spermatozoa 

      Tsantarliotou, M. P.; Taitzoglou, I. A.; Goulas, P.; Kokolis, N. A. (2002)
      The aim of this study was to investigate the effect of dexamethasone on acrosin activity of spermatozoa in Chios rams during autumn (breeding season for sheep in Greece), in correlation with possible changes in blood ...

    • Gossypol-induced inhibition of plasminogen activator activity in human and ovine acrosomal extract 

      Taitzoglou, I. A.; Tsantarliotou, M.; Kouretas, D.; Kokolis, N. A. (1999)
      The effect of gossypol-a polycyclic compound isolated from cotton seeds-on the plasminogen activator activity of man and ram acrosomal extracts was explored in vitro. The action of gossypol on the plasminogen activator ...

    • The impact of frequently encountered cardiovascular risk factors on sexual dysfunction in rheumatic disorders 

      Anyfanti, P.; Pyrpasopoulou, A.; Triantafyllou, A.; Doumas, M.; Gavriilaki, E.; Triantafyllou, G.; Gkaliagkousi, E.; Chatzimichailidou, S.; Petidis, K.; Avagianou, P. A.; Zamboulis, C.; Aslanidis, S.; Douma, S. (2013)
      Traditional cardiovascular risk factors have been acknowledged as major contributors to sexual dysfunction in the general population. The purpose of this study was to explore their impact on sexual function in rheumatologic ...

    • Induction of the acrosome reaction in bull spermatozoa with plasmin 

      Taitzoglou, I. A.; Chapman, D. A.; Killian, G. J. (2003)
      Proteolytic enzymes appear to have an essential role in multiple phases of mammalian fertilization. Plasmin, the active enzyme of the plasminogen activation system that stimulates fibrinolysis and proteolysis has a less ...

    • Post-fertilization effects of chronic renal failure in male rats 

      Dimitriadis, F.; Giannakis, D.; Giotitsas, N.; Parldalidis, N.; Baltogiannis, D.; Saito, M.; Watanabe, T.; Gratsias, S.; Zikopoulos, K.; Pashopoulos, M.; Tsambalas, S.; Kalaboki, V.; Tsounapi, P.; Vlachopoulou, E.; Gekas, A.; Melekos, M.; Makridimas, G.; Dalkalitsis, N.; Georgiou, I.; Agapitos, E.; Loutradis, D.; Kanakas, N.; Miyagawa, I.; Sofikitis, N. (2009)
      P>We evaluated the potential for growth and intrauterine development of embryos generated from the fertilization of oocytes with spermatozoa recovered from animals with chronic renal failure (CRF). Group A included ...

    • Sperm DNA fragmentation measured by Halosperm does not impact on embryo quality and ongoing pregnancy rates in IVF/ICSI treatments 

      Anifandis, G.; Bounartzi, T.; Messini, C. I.; Dafopoulos, K.; Markandona, R.; Sotiriou, S.; Tzavella, A.; Messinis, I. E. (2015)
      Sperm DNA fragmentation (SDF) has been proposed to be one of the main markers regarding male infertility. A prospective study was performed to assess primarily whether sperm DNA damage has any impact on embryological data ...
