The Impact of Different Equilibration Methods on the Cryopreservation Effectiveness of Boar Semen

Veterinary Medicine and Science, Volume 12, Issue 2, March 2026.
This study compared the effects of one‐step and two‐step balanced treatment methods for cryopreservation of boar semen and evaluated their impact on sperm quality after thawing. The optimized balanced treatment method improved sperm integrity and antioxidant capacity, and reduced apoptosis and oxidative damage. These findings provide practical guidance

Antioxidant supplementation of cryopreservation extenders improves post-thaw sperm viability in the red-crowned toadlet, Pseudophryne australis

Frontiers in Amphibian and Reptile Science
Amphibians are currently experiencing the highest extinction rate of any vertebrate class. Gamete cryopreservation and the biobanking of genetic resources are important conservation tools to safeguard the genetic diversity of imperiled species.

Rabbit sperm cryopreservation: A review

Animal Reproduction Science, 2009
Sperm cryopreservation is a great challenge, since many sperm are irreversibly damaged or present altered functionality after the whole process. Although components of extenders for sperm cryopreservation are quite similar between species, sperm from each of the species present peculiarities that force researchers to optimize the extenders and ...

One number to rule them all: The Wildlife Sperm Index for standardized gamete assessment

Methods in Ecology and Evolution, Volume 17, Issue 3, Page 705-717, March 2026.
Abstract In wildlife conservation, breeding programmes focused on reintroduction are critical to recovering endangered species. Assisted reproductive technologies (ARTs) and biobanking play pivotal roles in these efforts but depend on high‐quality gametes.

Evaluation of microRNA expression profiles in human sperm frozen using permeable cryoprotectant-free droplet vitrification and conventional methods

Asian Journal of Andrology
For sperm cryopreservation, the conventional method, which requires glycerol, has been used for a long time. In addition, the permeable cryoprotectant-free vitrification method has been continuously studied.

Evaluation of the Effects of Nicotinic Acid and Folic Acid on Morphology, Membrane Integrity and Quality of Sperm Chromatin Concentration in Normozoospermic Men during Cryopreservation.

مجله علمی دانشگاه علوم پزشکی کردستان, 2022
Background and Aim: Sperm cryopreservation is an important assisted reproductive technique. However, due to increased production of reactive oxygen species and oxidative stress, it can impair sperm function and reduce quality of fertility.

Role of glucose in enhancing life and potency of Cirrhinus mrigala spermatozoa during cryopreservation [PDF]

, 2015
Cryopreservation of fish gametes is an emerging technology and breeding with cryopreserved gametes is advancement in fish seed production. Success of cryopreservation is evaluated by the post - thaw motility of the spermatozoa, an for which energy is ...

Spermatogenesis and Morphology of the Male Reproductive Tract of the Turtle Kinosternon scorpioides

Anatomia, Histologia, Embryologia, Volume 55, Issue 2, March 2026.
ABSTRACT The scorpion mud turtle (Kinosternon scorpioides), a freshwater chelonian widely distributed in South and Central America, presents gaps in the microscopic and ultrastructural characterisation of its male reproductive system. This study provides a comprehensive characterisation of the testes, epididymides, and deferent ducts of adult males ...

Lactate inhibits glucose‐induced zigzag motility and enhances linear motility in bull spermatozoa by suppressing glycolysis

Andrology, Volume 14, Issue 3, Page 933-945, March 2026.
Abstract Background Energy metabolism and substrate balance are critical determinants of sperm motility and fertility. Linear motility is necessary for sperm forward movement, whereas hyperactivated motility is a prerequisite for fertilization. The preference of metabolic pathways depends on substrate availability which controls sperm motility. However,
