Norepinephrine content was reduced to undetectable levels in the cauda epididymidis in all guanethidine groups after 3 wk of treatment and was reduced to 7. It has been documented that combined exposure to arsenic and organophosphates result in increased levels of ROS in blood and tissues [ 42 ]. Storage of bovine semen in liquid and frozen state. Related articles in Web of Science Google Scholar. Each experiment was performed by using sperm from a single donor and was done 6 times. Interestingly, simultaneous coexposure did not produce any adverse effect on sperm head morphology. Cadmium and diazinon caused significant changes on sperm morphology with varying effects on motility patterns.

Head: It has a compact nucleus with only chromatic substance and is surrounded by only a thin rim of cytoplasm. Wikimedia Commons has media related to Spermatozoa. Exp Cell Res. Gamete Research. An nigrosin-eosin stain is commonly used because it is effective, simple and, in addition to allowing sperm to be readily visualized, it is a so-called "live-dead" stain, allowing one to assess membrane integrity at the same time as morphology. Another stain that can be used, and is demonstrated below, is toluidine blue. An important part of any breeding soundness exam is an evaluation of sperm morphology.

Molecular Human Reproduction. The cumulus cells are embedded in a gel-like substance made primarily of hyaluronic acid, and developed in the ovary with the egg and support it as it grows. Advances in Experimental Medicine and Biology. This procedure is particularly useful for assessing acrosomal integrity.
