Cryopreservation is the most efficient method for long-term preservation of mammalian
sperm. However, freeze-thawing procedures may strongly impair the sperm function and …

Cryopreservation is an expanding strategy to allow not only fertility preservation for
individuals who need such procedures because of gonadotoxic treatments, active duty in …

Cryopreservation causes decreased sperm fertility potential due to reactive oxygen species
(ROS) production and physical-chemical damage, resulting in reduced sperm viability and …

Cryopreservation is known to induce oxidative stress in spermatozoa. Although melatonin
has powerful antioxidant properties, little is known about its effects on human sperm quality …

This study compares the effectiveness of the ultra-rapid and conventional freezing of sperm
from captive bovids, giraffids, cervids, ursids, a cercopithecid, a delphinid and a …

BACKGROUND Subfertility affects approximately 15% of all couples, and a severe male
factor is identified in 17% of these couples. While the etiology of a severe male factor …

The aim of this study is to evaluate the beneficial effects of N‐acetyl‐cysteine (NAC), alpha
lipoic acid (ALA) and combination of NAC+ ALA supplement in freezing medium on Sperm …

Human spermatozoa cryopreservation techniques are used to maintain and protect male
fertility in cases such as infertility and malignancy treatments. However, during …

In this study proteomics analysis was performed to investigate damage caused to ram sperm
by the freeze-thaw process. Sperm motility, viability, reactive oxygen species (ROS) and …

Objective To evaluate post-thawing sperm parameters in a large series of men
cryopreserving for different cancers and oligospermia. Design Retrospective observational …
