Objective Cryopreservation of human spermatozoa is fundamental in assisted reproductive
technology. At present, slow freezing techniques are widely used for sperm …

Study question Does cryoprotection of spermatozoa using a vitrification protocol with
improved cryoprotective agents and a novel device for large storage lead to better outcomes …

Objectives Sperm cryopreservation has great potential for male infertility treatment as used
in assisted reproduction technology (ART). There are a variety of cryopreservation methods …

Purpose To evaluate whether sperm preparation (swim-up technique) before freezing
improves the percentages of sperm motility, sperm viability, and non-apoptotic spermatozoa …

In this study, we compared the effects of repeated freezing/thawing of human sperm by our
in-house method of rapid freezing with slow programmable freezing. Sperm samples from …

Slow freezing is the most commonly used technique for the cryopreservation of spermatozoa
in clinical practice. However, it has been shown to have a negative impact on sperm function …

Human sperm vitrification is a new cryopreservation method. This study compared the
effects of rapid freezing and vitrification on various sperm parameters, hyaluronan-binding …

Human spermatozoa cryopreservation has significantly improved over the last few decades,
but the actual protocols are neither optimal nor standardized between different laboratories …

OBJECTIVE: To evaluate the ability of two cryopreservation methods and three
cryoprotectants to preserve sperm quality. DESIGN: A prospective clinical study. SETTING …

In the 1960s, sperm cryopreservation was developed as a method to preserve fertility.
Currently, techniques for the cryopreservation of human spermatozoa have been widely …
