Human sperm mitochondrial function related to motility：a flow and image cytometric assessment
Human sperm mitochondrial function motility cytometric assessment
2009/2/23
Current evaluation of male fertility, routinely estimated by sperm count, motility, and morphology, provides only crude information about the fertility state of individuals. Both flow and image cyto...
Vasopressin receptors in human seminal vesicles：identification, pharmacologic characterization, and comparison with the vasopressin receptors present in the human kidney
Vasopressin receptors human seminal vesicles identification pharmacologic characterization
2009/2/23
Because of the presence of a high density of vasopressin receptors in the epithelial cells of porcine seminal vesicles similar to the V2 vasopressin receptors of renal tubules, human seminal vesicle...
Identification of a potential FSH modulatory protein in human testis and seminal plasma
potential FSH modulatory protein human testis seminal plasma
2009/2/23
A variety of factors capable of inhibiting the in vitro binding of FSH to its receptor have been identified in gonadal tissues from males and females. Interest in these factors has been stimulated b...
Phosphatidylcholine synthesis in human spermatozoa
Phosphatidylcholine synthesis human spermatozoa
2009/2/23
To clarify the mechanism of phospholipid synthesis in spermatozoa, fresh human spermatozoa were incubated with labeled fatty acids and 1-acyl-lysophosphatidyl choline (LPC) in the presence or abse...
Secretion of plasminogen activator in response to follicle-stimulating hormone in culture medium of human testicular cells from biopsy specimens
plasminogen activator follicle-stimulating hormone culture medium human testicular cells
2009/2/23
Testicular cells from human biopsy specimens were cultured and plasminogen activator secreted into the medium was investigated. Follicle stimulating hormone stimulated plasminogen activator secret...
Cytochalasin D inhibits penetration of hamster eggs by guinea pig and human spermatozoa
Cytochalasin D inhibits penetration hamster eggs guinea pig human spermatozoa
2009/2/23
Fertilization experiments using zona-free hamster eggs and spermatozoa from both guinea pig and human were conducted in the presence of cytochalasin D to evaluate the possible role of actin filame...
The effect of tumor necrosis factor on human sperm motility in vitro
tumor necrosis factor human sperm motility
2009/2/23
Tumor necrosis factor (TNF alpha) is present in elevated levels in peritoneal fluid from infertile women with endometriosis. The effect of TNF alpha on human sperm motility in vitro was evaluated ...

Fifty-one patients with obstructive azoospermia caused by blockage at the caput epididymidis have been followed for 4 years after undergoing "specific tubule" vasoepididymostomy, bypassing the cor...
Synchronous assay for human sperm capacitation and the acrosome reaction
human sperm capacitation acrosome reaction
2009/2/23
A synchronous acrosome reaction system was established for human spermatozoa. Seminal plasma is removed from the spermatozoa by centrifugation and the washed spermatozoa are capacitated in a modif...
A simple, clinical assay to evaluate the acrosin activity of human spermatozoa
acrosin activity human spermatozoa
2009/2/23
Acrosin, a sperm-specific acrosomal proteinase, has an essential role in the fertilization process. Low levels of acrosin appear to be associated with subfertility and infertility, and the acrosin a...
