Positive effects of in-vitro Myo-inositol supplementation of cryopreserved human sperm on the outcome of cryopreservation: a randomized controlled trial
OBJECTIVE _Myo_-inositol is a naturally occurring component of vitamin B complex that is involved in cellular signaling pathways. There is a growing evidence on the potential beneficial effects of _Myo_-inositol supplementation on both natural and assisted fertility. The objective of this study was to investigate the effects of _in_ vitro _Myo_-inositol supplementation of cryopreserved human semen on the post-thaw sperm ... Read more

High seminal oxidation reduction potential in cryopreserved semen from infertile men is a marker of poor post-thaw sperm quality

High seminal oxidation reduction potential in cryopreserved semen from infertile men is a marker of poor post-thaw sperm quality
OBJECTIVE Cryopreservation causes deleterious effects on human spermatozoa due to freezing and thawing, leading to decreased cryosurvival rates (CSR). The objectives of this study were to assess levels of oxidation-reduction potential (ORP) in cryopreserved semen of infertile men, and to determine their relationship to post-thaw sperm parameters. DESIGN A prospective cohort study. MATERIALS AND METHODS The study included 28 semen ... Read more
