Effect of low-density lipoprotein addition to soybean lecithin-based extenders on bull spermatozoa following freezing-thawing–preliminary results
bull sperm cryopreservation sperm motility viability cryoprotectant
2016/12/20
Soybean lecithin-based extenders represent an alternative to extenders containing egg yolk, but there has been discussion about their cryoprotective efficacy. Low-density lipoprotein (LDL) was proved ...
Exploration of natural cryoprotectants for cryopreservation of African catfish, Clarias gariepinus, Burchell 1822 (Pisces: Clariidae) spermatozoa
egg yolk honey glucose coconut water
2015/7/7
Toxicity is a major limitation to successful spermatozoa cryopreservation of fish. Due to this
problem, it is critical to find potential cryoprotectants which are more environmental-friendly, non-to...
Oxidative stress and motility in tench Tinca tinca spermatozoa
tench sperm activating medium osmolality
2015/7/7
It was hypothesized that sperm hypotonic exposure can provoke oxidative
stress which could be involved in sperm quality degradation. Our study aimed to describe spermatozoa motility
parameters and...
Comparison of oxidant and antioxidant status of seminal plasma and spermatozoa of several fish species
antioxidant enzymes oxidative stress fish sperm
2015/6/24
Oxidant and antioxidant activity in seminal plasma was compared with that in spermatozoa of teleost (common carp Cyprinus carpio and brook trout Salvelinus fontinalis) and chondrostean (Russian sturge...
Relationship between abnormal spermatozoa and seminal plasma free amino acids in boars
boars semen morphologically abnormal spermatozoa seminal plasma free amino acids
2015/6/4
The objective of this study was to provide some data on concentrations of seminal plasma free amino acids (FAAs) in order to compare these values with different total contents of morphologically abnor...
Pig Spermatozoa Defect in Acrosome Formation Caused Poor Motion Parameters and Fertilization Failure through Artificial Insemination and In vitro Fertilization
Boar Sperm Motion Parameters In vitro Fertilization Acrosome Defect
2016/5/17
The selection of morphologically normal spermatozoa is critical to obtain high breeding performances in boar breeding farms and artificial insemination (AI) centers. Parameters for the selection of se...
Effect of Cholesterol-loaded-cyclodextrin in Presence and Absence of Egg Yolk during Freezing Step on Quality of Markhoz Buck’s Spermatozoa
Markhoz Goat Cholesterol Cyclodexterin Cryopreservation Spermatozoa Buck
2016/5/6
Cryopreservation protocols induce partially irreversible damage to mammalian sperm plasma membranes. Previous studies have indicated that adding cholesterol to the plasma membrane, as cholesterol-load...
The Effect of Various Concentrations of Taurine during In vitro Fertilization on the Development of Bovine Embryos Fertilized with Spermatozoa from Three Different Bulls
Taurine In vitro Fertilization Embryonic Development Bull Variation
2016/5/5
We investigated the effect of various concentrations of taurine during in vitro fertilization (IVF) on the embryonic development up to the blastocyst stage of bovine oocytes fertilized with three diff...
The Effect of Proctodeal Gland Foam, Diluent and Dimethylacetamide Addition on Morphology and Fertilising Ability of Japanese Quail (Coturnix japonica) Spermatozoa

extenders fertility quails spermatozoa morphology
2009/7/30
The effect of quail semen dilution with three extenders : Lake's, Ringer's and Tyrod's on morphology and fertility trials of unstored spermatozoa was evaluated. Semen was collected twice a week by mal...
Changes in boar semen with a high and low level of morphologically abnormal spermatozoa
boars semen quality morphological analysis spermatozoa different development
