Walton and Wethammentioned the probability that a structure for the storage of sperm existed in the genitalia of the hen. It was considered unlikely that the life-duration of spermatozoa could be retained for the three to five weeks reported by Barfurth, Payne, Crewand others, without some ...
Key words: Hemoglobin, primary structure, sperm whale, oxygen affinity, heterogeneity.Sperm whale belongs to the order Cetacea and iswell known for its remarkable diving abilities. Inorder to understand the basis for this unusualability physiological studies have been carriedout. At the molecular ...

The prostate gland is a walnut-size structure that is located below your bladder and in front of your rectum. The prostate gland contributes additional fluid to the ejaculate. Prostate fluids also help to nourish your sperm. The urethra, which carries the ejaculate to be expelled during orgasm,...
The two accessory bodies have a crescent-moon shape in the mature sperm, but at the beginning of spermiogenesis they are small structures lateral to the axoneme, later assuming a crescent-moon structure. A flattened cistern located between the axoneme and the plasma membrane is present in the...
In addition, it induced histoarchitectural changes in testes of rats. However, FIS treatment resulted in remarkable improvements in testicular and sperm parameters. Therefore, it was inferred that FIS could serve as a therapeutic candidate against arsenic-generated male reproductive toxicity attributing ...

Structure: Sperm are microscopic cells consisting of a head, midpiece, and tail. The head contains genetic material, the midpiece contains mitochondria for energy production, and the tail allows for motility. Mobility: Sperm are highly motile, using their tail to swim towards the ovum through va...
