Sperm enrichment from poor semen samples by double density gradient centrifugation in combination with swim-up for IVF cycles

10 Feb 2020

Abstract excerpt

Sperm preparation in IVF cycles using density gradient centrifugation (DGC) in combination with swim-up (SU) has been widely adopted in reproductive centres worldwide. It is a fact that the sperm recovery rate following one DGC from poor semen samples (showing liquefaction defects/containing too many unresolvable clots or rare sperm) is relatively low. Our results showed that double DGC (DDGC) is effective at...
