Cryopreservation Effects on Ram Sperm Ultrastructure [PDF]

open access: yesBiopreservation and Biobanking, 2020
Cryoprotectants are known to have protective effects against cryodamage to spermatozoa. In this study, the cryoprotective effects of two cryoprotectants (glycerol, ethylene glycol) and cryoprotectants/trehalose combinations on frozen-thawed ram spermatozoa were investigated at the ultrastructural level. For this purpose, ejaculates collected from Konya

CRYOPRESERVATION OF REPRODUCTIVE PRODUCTS AS AN EFFECTIVE METHOD FOR PRESERVING THE BIODIVERSITY OF STURGEON FISH SPECIES (REVIEW)

open access: yesRibogospodarsʹka Nauka Ukraïni, 2016
Purpose. In recent years, cryopreservation of reproductive products has widely been used as one of the accessible and in some cases the only ways of preserving and supporting the number of endangered fish species including sturgeon fish species ...

Effect of Honey, Coenzyme Q10, and β-Carotene/α-Tocopherol as Novel Additives in Rabbit-Sperm Cryopreservation Extender

open access: yesAnimals, 2023
The effectiveness of rabbit-sperm cryopreservation is still below average compared to other domestic species. After the sperm cryopreservation process, post-thawing parameters like motility and membrane integrity are significantly compromised. The use of

Effects of cryopreservation on the ultrastructure and enzyme activities of rare minnow (Gobiocypris rarus) sperm

open access: yesAquaculture Reports
In the process of testing the Chinese rare minnow (Gobiocypris rarus) sperm motility before and after cryopreservation, it was found that sperm motility decreased significantly after cryopreservation.

REVIEW: Current Status of Extenders and Cryoprotectants on Fish Spermatozoa Cryopreservation [PDF]

open access: yes, 2005
An important component of many studies of cryopreservation of fish spermatozoa is the type of extenders and cryoprotectants. The suitability of extenders and cryoprotectants differs from one fish to another.

Testicular structure, spermatogenesis and sperm cryopreservation in the African clariid catfish Heterobranchus longifilis (Valenciennes, 1840) [PDF]

open access: yes, 1996
The morphological and physiological characteristics of the testes and the sperm of the catfish #Heterobranchus longifilis$ (Val.) are presented. The effect of cryopreservation on the fertilizing capacity of the sperm was also evaluated.

Sperm cryopreservation reduces offspring growth [PDF]

open access: yesProceedings of the Royal Society B: Biological Sciences, 2019
Sperm cryopreservation is routinely used in reproductive medicine, livestock production and wildlife management. Its effect on offspring performance is often assumed to be negligible, but this still remains to be confirmed in well-controlled within-subject experiments.
