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...
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...
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...
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...
Testicular cells from human biopsy specimens were cultured and plasminogen activator secreted into the medium was investigated. Follicle stimulating hormone stimulated plasminogen activator secret...
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...
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...
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...
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...
Multivariate discriminant analysis was used to evaluate the usefulness of computer image analysis of sperm movement characteristics and differential patterns of sperm tail swelling after hypoosmot...
Serum FSH, LH, and testosterone were studied in 114 infertile men with poor sperm production. Testicular biopsies were taken and classified morphologically. In 90 specimens, the pattern of convers...
A sperm motility inhibitor from human seminal plasma was purified and characterized. The purification procedure includes dialysis, ion exchange chromatography on SP-Sephadex C-25 and adsorption chro...
The effects of ethanol on the loss of the human sperm acrosome, as determined by the chlortetracycline fluorescence assay and by indirect immunofluorescence assay, were assessed over 6 hours during ...
The histologic distribution of a prostatic secretory protein of 94 amino acids (PSP94) and its mRNA were examined simultaneously by conventional immunohistochemistry and in situ hybridization histoc...
