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...
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...
A comparison of the alkaline proteinase activity of human seminal plasma, the seminal non-gamete cellular material and spermatozoa was made by gelatin-sodium dodecyl sulfate-polyacrylamide gel elect...
Human seminal plasma contains large amounts of transferrin, which is a protein secreted mostly by Sertoli cells. It has been suggested that the concentration of transferrin may serve as a possible c...
We have studied some characteristics of alpha-1,4-glucosidases in human male reproductive organs in order to obtain information on the origin of the enzyme in seminal plasma. Acid and neutral enzyme...
This work was undertaken to determine the identity of the major androgen-dependent 15,000 molecular weight protein previously observed on SDS polyacrylamide gel electrophoresis of both dog prostate ...
Biochemical aspects of post-testicular sperm maturation have been studied. Partial purification of either human or ram seminal plasma yields a heat-stable, acidic protein which is a Ca2+-dependent...
Human seminal plasma, freed of spermatozoa by centrifugation, inhibited binding of iodine-125 (125I)-hFSH to receptors in calf testes. Binding inhibition (BI) was seen in seminal plasma from intact ...
Ejaculates from normal and castrated bulls were evaluated for the presence of inhibin-like activity. Inhibin activity found in the seminal plasma of normal bulls became undetectable after castrati...
Semen samples and blood were collected from 57 men: 23 normospermic, 20 oligospermic, 10 vasectomized, two with Klinefelter's syndrome, and two with Sertoli-cell—only syndrome. Inhibin was measure...
The authors found that DOPA/5-HTP decarboxylase was present in the human seminal plasma and that its activity was lower in fertile men than in infertile men. The Km and Vmax of the enzyme were, re...
In order to investigate the origin of an 84-kDa protein with ABH blood-typing antigen activity (p 84) and its concentration in human seminal plasma, a monoclonal antibody (mAb p 84) was produced....
It has been suggested that insulin-like growth factor (IGF)-1 plays an important role in the regulation of spermatogenesis in the testes. In the present study, concentrations of total IGF-1 we...
Human prostatic secretion and seminal plasma contain certain protein kinase activities. Protein kinases play important roles in regulating a vast variety of cellular functions. The objective of this...
Interleukin-12 (IL-12) is a unique cytokine that recently has drawn considerable attention because of its immunomodulatory properties and its possible involvement in several normal physiological a...
