Abstract Aim: To 1) compare post‐wash and post‐thaw parameters of sperm processed with
PureSperm density gradient technique and swim‐up method; and 2) test the efficacy of two …

Functional differences among fresh 24‐hour extended and cryopreserved human
spermatozoa were assessed using both computer‐assisted semen analysis (CASA) and …

Objective To determine if conventional sperm parameters, specific characteristics of sperm
motion determined by computer-aided semen analysis (CASA), sperm penetration assay …

To improve the quality of cryo‐preserved sperm, ejaculated semen was concentrated prior to
freezing by means of continuous‐step density gradient centrifugation. Freezing was …

Objective: To investigate effects of cryopreservation on sperm motility and DNA integrity.
Design: Pre-cryopreservation and post-cryopreservation analysis of motility and DNA …

OBJECTIVE: To compare the efficacy of rapid freezing (RF) and slow programmable
freezing (SPF) of human spermatozoa. DESIGN: Experimental study. SETTING: University …

The purpose of this study was to determine the effects of a simplified 80% Mono-Percoll
sperm separation procedure on both normal and male factor semen samples compared with …

Human sperm cryopreservation is characterised to this day by sub-optimal success rates.
Interestingly, a traditional approach to improving post-thaw outcome has been to integrate …

Objective To analyze cases in which no sperm could be identified after thawing among
cryopreserved samples of rare or very low concentrations of sperm. Design Retrospective …

The aim of our study was to evaluate the efficiency of 4 density gradient media for motile
cryopreserved spermatozoa selection to Percoll (Kabi Pharmacia, Uppsala, Sweden) and to …
