PROTEOMICS, 2009
Abstract The spermatozoon is an accessible cell which can be easily purified and therefore it is particularly well suited for proteomic analysis. It is also an extremely differentiated cell with very marked genetic, cellular, functional and chromatin changes as compared to other cells, and has profound implications for fertility ...

Trends in Cell Biology, 2014
Sperm are guided to the egg by a gradient of chemical attractants - a process called chemotaxis. The binding of the chemoattractant to receptors on the surface of the flagellum triggers a cascade of signaling events that eventually lead to an influx of Ca(2+) ions.

Arabinogalactan proteins at the cell surface ofBrassica sperm andLilium sperm and generative cells
Sexual Plant Reproduction, 1996Antibodies to arabinogalactan proteins were tested for binding to sperm cells ofBrassica campestris and to generative cells and sperm ofLilium longiflorum. Two monoclonal antibodies, JIM8 and JIM13, bound toBrassica sperm in pollen grains and pollen tubes and to isolated sperm.

Interaction of Sperm with Somatic Cells
Science, 1974We regret we did not cite the earlier work of our colleagues in the field of gynecology mentioned above; we disagree with their contention that the methods were put to the same use and achieved the same results. Our study dealt with nonphagocytic spermatozoal transfer of genetic information to cultured somatic cells. Coppleson and Reid regarded sperm

2006
Originally published in 2006, this is a comprehensive and definitive account of the human male gamete. The volume summarizes many unique and revealing characteristics of the sperm cell. It provides a detailed overview of human sperm production, maturation and function, and looks at how these processes affect and influence fertility, infertility and ART.

Impact of sperm cell source on the results of intracytoplasmic sperm injection
Archives of Gynecology and Obstetrics, 2014There is an ongoing debate whether the source of sperm cells, the etiology or the extent of male factor infertility has influence on the outcome of ICSI cycles.The results of intracytoplasmic sperm injection (ICSI) according to the source of spermatozoa in patients with severe male factor infertility were compared in a retrospective study: 249 couples ...

Zygote, 2016
SummaryThe resazurin reduction test (RRT) is a useful technique to assess the metabolic rate of sperm cells. RRT depends on the ability of metabolically active cells to reduce the non-fluorescent dye resazurin to the fluorescent resorufin. The aim of this study was to develop a vital fluorometric method to evaluate metabolic activity of rabbit sperm ...

Human sperm cells express CD44
Fertility and Sterility, 2002To determine whether CD44 is expressed by human sperm cells.Prospective study.Assisted conception unit and university research laboratory.Fourteen normal fertile donors.None.Enzyme-linked immunoassay was used to measure the concentration of CD44 in samples of human sperm cells. Immunocytochemistry using a fluorescent antibody system was used to confirm

Motility, viability, and calcium in the sperm cells
Systems Biology in Reproductive Medicine, 2013Sperm cells are complicated in vitro models. Their viability is limited, and physiology is complex. The study of their properties is of great application in the animal production as viable and functional gametes are essential. It has been shown that the decrease of sperm cell viability parallels an increase of the reactive oxygen species (ROS ...
