Tudor Domain Containing Protein TDRD12 Expresses at the Acrosome of Spermatids in Mouse Testis
Tdrd12 Tudor Spermatogenesis Acrosome Spermatid Testis
2016/7/27
Tdrd12 is one of tudor domain containing (Tdrd) family members. However, the expression pattern of Tdrd12 has not been well studied. To compare the expression levels of Tdrd12 in various tissues, real...
Protective effects of the antioxidants curcumin, ellagic acid and methionine on motility, mitochondrial transmembrane potential, plasma membrane and acrosome integrity in freeze-thawed Merino ram sperm
curcumin ellagic acid methionine
2016/1/29
The aim of this study was to determine the effects of curcumin, ellagic acid and methionine on sperm parameters following the freeze-thawing of Merino ram semen. Ejaculates were collected via an artif...
Relationship between acrosome integrity changes and in vitro fertilising ability of bovine spermatozoa
bull spermatozoa acrosome embryos IVF
2015/10/9
This study was designed to investigate the characteristics of acrosomal changes during capacitation of bovine spermatozoa in relationship to in vitro fertility of individual bulls. Motile spermatozoa ...
Effect of acrosome reaction progress in frozen-thawed boar spermatozoa on the efficiency of in vitro oocyte fertilization
pig cryopreserved sperm assessment
2015/4/7
A good functional status of cryopreserved boar spermatozoa is very important for successful fertilization of porcine oocytes and in vitro embryo production. The purpose of the study was to evaluate th...
Functional evaluation of dog ejaculates with priority given to the aspect of acrosome integrity
dog ejaculate sperm analysis membrane and acrosome integrity
2015/1/27
38 ejaculates of dogs of various breeds from2to 6 years old were examined in a short-term 120 min survival test. The examination focused on the functional parameters of sperm (motility, percentage of ...
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...
Synchronous assay for human sperm capacitation and the acrosome reaction
human sperm capacitation acrosome reaction
2009/2/23
A synchronous acrosome reaction system was established for human spermatozoa. Seminal plasma is removed from the spermatozoa by centrifugation and the washed spermatozoa are capacitated in a modif...
Evidence for a role of cyclooxygenase（prostaglandin synthetase）and prostaglandins in the sperm acrosome reaction and fertilization
spermatozoa fertilization acrosome reaction cyclooxygenase prostaglandin inhibitor
2009/2/23
Three cyclooxygenase (prostaglandin synthetase) inhibitors, indomethacin, phenylbutazone, and oxyphenbutazone, decreased fertilization in vitro when mixed with capacitated mouse spermatozoa before a...
A study of phospholipase in albumin and its role in inducing the acrosome reaction of guinea pig spermatozoa in vitro
capacitation acrosome reaction spermatozoa
2009/2/19
Phospholipase activity associated with guinea pig spermatozoa during capacitation and the acrosome reaction (AR) was determined by measuring the production of [14C] glycerylphosphorylcholine (GPC) f...
The Effect of Inhibitors of Trypsin and Phospholipase A2 on the Penetration of Zona Pellucida-free Hamster Eggs by Acrosome-reacted Hamster Sperm
Trypsin Phospholipase A2 Penetration Zona Pellucida-free Hamster Eggs
2009/2/19
The involvement of a trypsin-like enzyme and a phospholipase A2 in hamster sperm-egg fusion was investigated. Previously acrosome-reacted sperm and zona pellucida-free eggs were incubated in a low...
The Effect of ATP Depletion upon the Acrosome Reaction in Guinea Pig Sperm
sperm motility ATP depletion acrosome
2009/2/19
The suspension of guinea pig spermatozoa in substrate-free medium results in the cessation of sperm motility and a 94% reduction in adenosine triphosphate (ATP) levels within minutes. ATP depletion wa...
Acrosome reaction in dog sperm is induced by a membrane-localized progesterone receptor
Canine spermatozoa prostatic fluid
2009/2/18
The aim of this study was to investigate whether the dog sperm acrosome reaction can be induced by progesterone and whether the action of progesterone is mediated by binding of progesterone to a r...
