Some of these applications are outlined below:Fertility treatments: Oocytes, sperm samples and embryos can all by cryopreserved to aid fertility treatment. ...
α-chymotrypsin can significantly shorten the liquefaction time of semen and reduce its viscosity, but it has no obvious effect on sperm ...
In order to maximise the potential for good quality embryos, optimum conditions must be met and environmental stress must be reduced as much as possible. To achieve this eggs, sperm and the resulting embryos should be immediately transferred to the incubator. ...
The results demonstrated that egg production and sperm quality were decreased upon exposure to MEHP, which also resulted in reduced egg diameter and eggshell as well as decreased egg protein content. ...
Bisphenol A acts as an endocrine disruptor, affects animal reproductive success in vivo, and affects sperm functions in vitro at environmentally relevant concentrations leading to reduction in sperm motility and fertilizing ability in fish. ...
No histological alterations were observed in gonads of TBT‐exposed animals, however, sperm storage in the seminal receptacle was drastically decreased in exposed females. ...
The results of the present study indicated that fertility, cloacal gland area, sperm concentration and serum testosterone were reduced significantly (p < 0.05) on day14 in the norfloxacin treated birds. ...
A tiered investigative approach was employed to characterize and identify substances responsible for the persistent toxicity of a municipal primary‐treated effluent to gametes of the Hawaiian sea urchin, Tripneustes gratilla. EPA Toxicity Identification Evaluation (TIE) procedures were modified to account for the tolerance of T.gratilla gametes to various sample manipulations. Microtox rapid ...
Volume, density, total number, and motility and velocity of sperm were measured to assess testicular function. At 0.2 µg/L, BPA reduced steroidogenetic acute regulatory protein and increased estrogen receptors (ERs) messenger RNA (mRNA) transcript (ERβ1 in liver and ERβ2 in testis) after 90 d. ...
The authors report different parameters of male reproductive behavior, brain, and gonadal aromatase expression, as well as sperm quality in an internally fertilizing fish species (Jenynsia multidentata, Jenyns) exposed to environmentally relevant concentrations of 17β‐estradiol (E2). ...
Although testicular weight was lower at the Moody Pond site, histology, plasma testosterone, and sperm number were similar to these parameters in Washburn Pond animals. ...
