Acute effects and long-term sequelae of 1,3-dinitrobenzene on male reproduction in the rat. I. Sperm quality, quantity, and fertilizing ability
long-term sequelae 1,3-dinitrobenzene male reproduction rat
2009/2/23
Groups of eight adult male rats were given a single oral dose of 0 or 48 mg/kg of 1,3-dinitrobenzene and sacrificed at 1, 2, 4, 8, 16, 24, 32, 72, and 175 days posttreatment. The groups killed at 17...
Relationship Between Fertilizing Ability and cAMP in Human Spermatozoa
capacitation of human spermatozoa cAMP in human spermatozoa fertilization of zona-free hamster eggs
2009/2/19
The goal of this study was to investigate the relationship between cAMP and the fertilizing ability of human spermatozoa. Levels of cAMP were measured in human spermatozoa during 6-hour in vitro i...
Evidence for a Role of Post-Ovulatory Cumulus Components in Supporting Fertilizing Ability of Hamster Spermatozoa
fertilization in vitro capacitation acrosome reaction egg-cumulus complex golden hamster
2009/2/19
A completely chemically defined culture medium was used to investigate the role of egg-cumulus complex (ECC) components in supporting sperm fertilizing ability. Defined sperm motility-stimulating ...
A Competitive In Vitro Assay of Human Sperm Fertilizing Ability Utilizing Contrasting Fluorescent Sperm Markers
Spermatozoa fertilization sperm motility
2009/2/19
Fluorescein isothiocyanate (FITC) and tetramethyl rhodamine isothiocyanate (TRITC) were evaluated for use as contrasting fluorescent labels on living human spermatozoa. Unlabeled (control), FITC...
The impact of reactive oxygen species on bovine sperm fertilizing ability and oocyte maturation
Spermatozoa fertilization development xanthine oxidase
2009/2/17
The objective of this study was to examine the effects of reactive oxygen species (ROS) on bovine sperm function and on the developmental competence of in vitro-matured bovine oocytes. In a first se...
Synchronous assessment of sperm motility and fertilizing ability in the hamster following treatment with alpha-chlorohydrin
Synchronous assessment sperm motility fertilizing ability
2009/2/13
To investigate the relationship between sperm motion parameters and fertilizing ability, a model was developed to assess both of these endpoints synchronously using a toxicant that inhibits sperm mo...
The ethane dimethanesulfonate-induced decrease in the fertilizing ability of cauda epididymal sperm is independent of the testis
Epididymis sperm maturation in utero insemination fertilization toxicant
2009/2/12
Several decades ago it was reported that when adult male rats were exposed to a single injection of 50 mg/kg body weight ethane dimethanesulfonate (EDS) and mated with untreated females, average l...
Accessory sperm as an indication of fertilizing ability of rabbit spermatozoa frozen in egg yolk-acetamide with detergent
Accessory sperm fertilizing ability of rabbit spermatozoa
2008/12/26
Many factors besides initial semen quality affect fertilization rates as sperm interact with the environment of the female reproductive tract. One of these factors is sperm transport, which can be eva...
