Quantitative Correlation Between Testicular Stem Cell Survival, Sperm Production, and Fertility in the Mouse After Treatment With Different Cytotoxic Agents
stem cells sperm production fertility radiation Adriamycin
2009/2/19
Treatment of mice with high doses of radiation or certain cytotoxic drugs results in killing of spermatogonial stem cells, a prolonged period of reduced sperm production, and infertility. In this ...

Electrophoretic and Chromatographic Properties of Boar Sperm Plasma Membranes:Antigens and Polypeptides with Affinity for Isolated Zonae Pellucidae
sperm plasma membrane zonae pellucidae
2009/2/19
Two methods were used to assess the ability of plasma membrane (PM) polypeptides to bind to isolated zonae pellucidae (ZP). Crossed immunoelectrophoresis patterns of detergent solubilized PM were co...
Sperm Motility and Histomorphometry of the Testis of the Genetically Obese Zucker Rat
Zucker rat testis sperm
2009/2/19
The reproductive system of male obese Zucker rats was studied to determine whether there are abnormalities in testis composition, organ weights, or sperm motility, which might contribute to their se...
Vasocystostomy in the Rabbit: Surgical Technique and Sperm Outflow
vasocystostomy surgery rabbit sperm urine
2009/2/19
The surgical technique employed for construction of bilateral vas-to-bladder fistulae (vasocystostomy) in the male rabbit is described. The method of collection and results of examination of sperm...
Several reports have suggested that human semen quality has declined throughout the world over the last few decades. Chemicals in the environment acting as endocrine disrupters have been implicated ...
Evaluation of oxidative DNA damage in human sperm and its association with male infertility
8-Hydroxydeoxyguanosine spermatozoa infertility
2009/2/18
Recently, there is increasing evidence suggesting that oxidative sperm DNA damage is closely associated with impaired sperm function and male infertility. 8-Hydroxydeoxyguanosine (8-OHdG) is consi...
Increased in vitro binding of fresh and frozen-thawed human sperm exposed to a synthetic peptide
Profertility peptide sperm-egg binding human
2009/2/18
Prosaposin is a well-characterized, approximately 68-kDa protein found in many tissues and as a normal component of human semen. A fragment of prosaposin apparently is involved in primary sperm-eg...
In vitro sperm-binding assay to distinguish differences in populations of human sperm or damage to sperm resulting from cryopreservation
Sperm quality fresh versus frozen semen
2009/2/18
Annually, >1.3 million men are members of couples seeking help because of infertility. Semen from many of these men contains reasonable numbers of motile and normal sperm, but for a subset of indivi...
Presence and tyrosine phosphorylation of c-met receptor in human sperm
tyrosine phosphorylation c-met receptor human sperm
2009/2/18
The c-met receptor is a p190MET tyrosine kinase proto-oncoprotein that through its binding to its ligand, designated hepatocyte growth factor (HGF), induces mitogenic, motogenic, and morphogenic act...
Acrosome reaction in dog sperm is induced by a membrane-localized progesterone receptor
Canine spermatozoa prostatic fluid
2009/2/18
The aim of this study was to investigate whether the dog sperm acrosome reaction can be induced by progesterone and whether the action of progesterone is mediated by binding of progesterone to a r...
Potential daily sperm production, Sertoli cell number, and seminiferous tubule characteristics in beef bulls fed conventional or gossypol-enriched diets
Potential daily sperm production Sertoli cell number seminiferous tubule characteristics
2009/2/18
The objective of this study was to determine the amount of germ cell degeneration throughout spermatogenesis in the bull and to determine if gossypol-enriched diets enhance that degeneration. Twenty...
An improved mouse sperm-oocyte plasmalemma binding assay: studies on characteristics of sperm binding in medium with or without glucose
Zona-free oocytes pronuclear zygotes in vitro fertilization
2009/2/18
Sperm binding to the oocyte plasmalemma is crucial to subsequent steps in fertilization. However, the usual in vitro assay for sperm-oocyte binding does not distinguish between nonspecific attachmen...
Comparison of fresh and cryopreserved human sperm attachment to bovine oviduct(uterine tube)epithelial cells in vitro
Sperm coculture sperm storage artificial insemination
2009/2/18
Formation of a prefertilization sperm reservoir in mammals is thought to occur via sperm cell attachment to fallopian tube or oviduct epithelial cells (OEC). Recent data suggests that such an interact...
Molecular cloning and developmental expression of the major fibrous sheath protein(FS 75)of rat sperm
Molecular cloning developmental expression major fibrous sheath protein(FS 75) rat sperm
2009/2/18
The fibrous sheath (FS) is a cytoskeletal structure that encases the axoneme in the principal piece of the spermatozoon tail. In the rat, it is composed of several proteins, of which a 75-kDa polype...
