The cryopreservation of spermatozoa was introduced in the 1960s as a route to fertility
preservation. Despite the extensive progress that has been made in this field, the biological …

A state of oxidative stress (OS) and the presence of reactive oxygen species (ROS) in the
male reproductive tract are strongly correlated with infertility. While physiological levels of …

In the field of assisted reproductive technology, female fertility preservation, particularly
ovarian tissue cryopreservation in adolescent cancer patients, has attracted much attention …

The cryopreservation of human spermatozoa has been an option for patients undergoing
chemo or radiotherapies since the late 1950s. Presently, there are different techniques for …

Infertility is an increasing global public health concern with socio-psychological implications
for affected couples. Remarkable advances in reproductive medicine have led to successful …

Cryopreservation causes cryoinjury to oocytes and impairs their developmental
competence. Melatonin (MLT) can improve the effect of cryopreservation in animal oocytes …

Sperm cells can be damaged during the semen cryopreservation process, decreasing their
fertilizing ability. Physical damage and oxidative stress may occur during the freeze–thawing …

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

Semen cryopreservation is an important tool for artificial breeding, species conservation and
human reproductive medicine. However, sublethal freezing damage remains an important …

Melatonin is a ubiquitous indoleamine hormone synthesized primarily by the pineal gland.
Diverse biological actions of melatonin involve quite complex mechanisms via its membrane …
