Effect of cryopreservation on mouse sperm. [PDF]
, 2010 Cryopreservation or freezing of sperm in the reproductive biology is still actual topic. Today is the only method used for sperm storage, whether for the purposes of assisted reproduction, or for scientific purposes.

Incubation Time And Its Effect On Sperm Motility Following Cryopreservation [PDF]
, 2019 The yellow-spotted monitor (Varanus panoptes) is an Australian lizard species which is severely impacted by the invasive cane toad. Previous attempts at sperm cryopreservation have shown promising post-thaw survival (∼ 45% motility), however the length ...

LASP1, a Novel Protein in Spermatozoa and Acrosome Reaction
Molecular Reproduction and Development, Volume 93, Issue 7, July 2026.LASP1 is expressed in spermatozoa, binds to F‐actin, and builds up the equatorial ring structure during acrosome reaction, which is important for hyaluronan receptor surface presentation. ABSTRACT LIM and SH3 protein 1 (LASP1) is a widely expressed scaffold protein associated with actin‐rich structures. In Lasp1‐knockout mice, reproductive defects such

Reactive Oxygen Species‐Induced Damage in Cryopreserved Bovine Sperm: Mitigation Strategies
Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.Cryopreservation of bovine sperm results in overproduction of ROS due to osmotic pressure variations, ice crystals and dysfunction of mitochondria, which causes lipid peroxidation, fragmentation of DNA, protein damage and ultimately decline of post‐thaw sperm quality.

Cryoprotectant effects of mangiferin on the quality of frozen-thawed boar sperm
Frontiers in Veterinary ScienceBoar sperm is particularly vulnerable to damage at low temperatures, leading to reduced efficiency in cryopreservation. This study aimed to analyze the effect of mangiferin (Man) on boar sperm cryopreservation efficiency. Various concentrations of Man (0,

Semen Cryopreservation in Testicular Cancer: Before or After Orchidectomy?
Andrology, Volume 14, Issue 5, Page 1272-1281, July 2026.ABSTRACT Background Fertility preservation in patients with testicular cancer remains a clinical priority, yet the optimal timing for sperm cryopreservation—before or after orchidectomy—remains a matter of debate. Objectives The aim of this study was to determine the optimal timing for semen cryopreservation and the best‐quality sample for ART.
