Cryopreservation of spermatozoa is becoming more important because of new clinical
requirements and current clinical practice. Despite the success of sperm cryopreservation …

Melatonin has a wide variety of beneficial actions at the level of the gonads and their
adnexa. Some actions are mediated via its classic membrane melatonin receptors while …

Cryopreservation harms spermatozoa at different levels and thus impairs their fertilizing
ability. The role of melatonin in protecting spermatozoa from different kind injuries has been …

Contents Melatonin is a ubiquitous molecule, present in a wide range of organisms, and
involved in multiple functions. Melatonin relays the information about the photoperiod to the …

While critical for male fertility preservation, cryopreservation damage reduces sperm quality
and fertilization potential. This study investigated whether the addition of mitochondrial …

In the Merino ram, it is unclear whether cryopreserved sperm function and fertility is
compromised when collected during the non-breeding season, when Merino ewes are …

The objective was to determine effects of slow‐release melatonin on post‐thaw sperm
quality in rams exposed to mild testicular heat stress (HS; scrotal neck insulation). Twelve …

Three field experiments were performed to determine the effects of melatonin implants on
the fertility of rams. The experiments were performed on three breeds (Rasa Aragonesa …
