The cryobiology of spermatozoa
Theriogenology, 2012The impact of successful cryopreservation of spermatozoa can be found in many fields, including agriculture, laboratory animal medicine, and human assisted reproduction, providing a cost-effective and efficient method to preserve genetic material for decades.

The unusually high content of phospholipid-bound polyunsaturated fatty acids (PUFA) in the sperm plasma membrane drew attention to their potential physiological significance. Docosahexaenoic acid (22:6) is quantitatively the most important fatty acid.

Spermatozoa as Functional Components of Robotic Microswimmers
Advances in Materials, 2017In recent years, the combination of synthetic micro‐ and nanomaterials with spermatozoa as functional components has led to the development of tubular and helical spermbots – microrobotic devices with potential applications in the biomedical and ...

Human Pathology, 1988
Spermatozoa have not previously been described within the prostate gland. Nine of one hundred prostates of nonhospitalized males obtained from autopsy during the course of medicolegal death investigation were found to contain spermatozoa. The potential role of spermatozoa in the pathogenesis of corpora amylacea/calculi formation, granulomatous ...

Capacitation of Rabbit Spermatozoa
Nature, 1958SUMMARY The capacity of rabbit spermatozoa to penetrate the zona pellucida of the ovum has been reported to depend upon pre-conditioning within the reproductive tract of the oestrous female. The present experiments show that spermatozoa can be capacitated in the uteri and uterine tubes of rabbits ovariectomized 1 month previously, in the ...

Rheotaxis of spermatozoa [PDF]
Proceedings of the Royal Society of London. Series B. Biological Sciences, 1961 1. The response of human and bull spermatozoa to vertical velocity gradients has been examined, the fluid flow being in horizontal planes. 2. Dead human and bull spermatozoa point downstream (negative rheotaxis) in the top half of a parabolic velocity gradient and upstream (positive rheotaxis) in the bottom half.

New research on the cooling and cryopreservation of mammalian spermatozoa is reviewed in the context of the older literature. Cryoinjury to a variety of cell organelles is regarded as being due to the two major stresses of cryopreservation, i.e., the ...

Cryopreservation of Spermatozoa
2016Cryopreservation is a technique that keeps the cells and tissues in a vital state, using cryogenic temperatures (196 C). Despite the first experiments of sperm preservation with snow dating back to the eighteenth century, it was only the discovery of the protective role of glycerol against freezing damage in the twentieth century and the use of liquid ...

Cyto and genotoxicities of graphene oxide and reduced graphene oxide sheets on spermatozoa
, 2014Concentration-dependent cyto and genotoxicities of graphene oxide (GO) and reduced GO (rGO) sheets on spermatozoa were studied. rGO sheets with various surface chemical states were achieved using hydrazine (N2H4) hydrothermal (HT) reactions and green tea

ACETYLCHOLINESTERASE IN BULL SPERMATOZOA [PDF]
Reproduction, 1964 Acetylcholinesterase occurs in the head, midpiece and tail fractions of sonically disrupted bull epididymal spermatozoa. The enzyme exhibits the characteristic substrate concentration optimum; 1\m=.\5X 10-5 m-eserine competitively inhibits the hydrolysis of the acetylcholine.
