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...
Suppression of steroid receptor-chromatin interaction by inhibitors present in ammonium sulfate-fractionated rat testicular androgen receptor preparations
steroid receptor-chromatin interaction inhibitors present ammonium sulfate-fractionated rat
2009/2/23
Tritiated androgen receptor complex was partially purified by ammonium sulfate precipitation at 15 to 37% saturation from rat testicular or prostatic cytosols. A greater amount of prostatic tritiate...
Cryopreservation of Spermatozoa and Artificial Insemination：Past, Present, and Future
cryopreservation semen quality bull semen human semen semen donors
2009/2/19
This review article is intended to provide an in-depth analysis of the principles and programs established, as well as problems overcome, that have led to a successful artificial insemination (AI) p...
Estrogen receptors are present in the epididymis of the rooster
Estrogen receptors epididymis rooster
2009/2/17
Our recent discovery that testicular germ cells and epididymal sperm contain active P450 aromatase suggests that the reproductive tract may be a target for estrogen. Therefore, the objective of th...
Hexokinase present in human sperm is not tyrosine phosphorylated but its antibodies affect fertilizing capacity
Hexokinase human sperm fertilization infertility
2009/2/16
The present study was conducted to investigate the presence of hexokinase in human sperm cell, its subcellular localization, its modulation and role in capacitation/acrosome reaction, and tyrosine...
Glycosidic specificity of fucosyltransferases present in rat epididymal spermatozoa
Glycosidic specificity fucosyltransferases present rat epididymal spermatozoa
2009/2/13
We have recently demonstrated multiple fucosyltransferase (FT) activity in rat spermatogenic cells. To complement these findings, here we identify and partially characterize the glycosidic linkage s...
Immunoreactive parathyroid hormone-related protein is present in human seminal plasma and is of prostate origin
Immunoreactive parathyroid hormone-related protein human seminal plasma
2009/2/12
Parathyroid hormone-related protein (PTHrP) is a regulatory peptide that has been associated with normal fetal growth and differentiation as well as the regulation of fetal calcium. We recently d...
Inhibition of steroidogenesis in neonatal Leydig cells by unknown factor（s）present in spent media of androgen-treated cultured testicular cells from adult rats
Leydig cell 5a-dihydrotestosterone methyltrienolone
2009/2/12
Treatment of cultured testicular cells from adult rats with 5 alpha-dihydrotestosterone (DHT; 10(-6) M) or the synthetic androgen methyltrienolone (R1881; 10(-6) M) inhibited Leydig cell 3 beta-hy...
Outcomes for Vasovasostomy Performed When Only Sperm Parts Are Present in the Vasal Fluid
Vasectomy reversal vasovasostomy infertility vasoepididymostomy vas deferens
2008/12/24
This article reviews the outcomes for vasovasostomy (VV) when only sperm parts were present in the vasal fluid. Thirtyfour patients who underwent bilateral (31) or unilateral (3) VV had either sp...
