Apparent fertility of human spermatozoa from the caput epididymidis
Apparent fertility human spermatozoa caput epididymidis
2009/2/23
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...
Receptor-mediated endocytosis of alpha 2-macroglobulin by principal cells in the proximal caput epididymidis in vivo
alpha 2-macroglobulin principal cells proximal caput epididymidis
2009/2/20
Micropuncture techniques were used to study receptor-mediated endocytosis of alpha 2-macroglobulin bound to colloidal gold (alpha 2M-gold) by principal cells in the proximal caput epididymidis of co...
Organ culture of rat caput epididymal tubules in a perifusion chamber
Organ culture rat caput epididymal tubules perifusion chamber
2009/2/20
We have been able to culture caput epididymal tubules from rats by modifying an organ culture system (Orgebin-Crist et al, 1980) which was used to culture rabbit corpus epididymal tubule segments. T...
Regulation of rat caput epididymidis contractility by prostaglandins
epididymis sperm transport prostaglandins rat
2009/2/20
Mechanical activity of the rat caput epididymidis in vitro was recorded using a videomicrography system. The effects of prostaglandin (PG)F2 alpha, PGE2, and aspirin on caput epididymidis contractil...
The male antifertility agents alpha chlorohydrin, 5-thio-D-glucose, and 6-chloro-6-deoxy-D-glucose interfere with sugar transport across the epithelium of the rat caput epididymidis
rat epididymis sugar transport antifertility
2009/2/19
The effects of the male antifertility agents alpha-chlorohydrin, 5-thio-D-glucose, and 6-chloro-6-deoxy-D-glucose on sugar transport (3H-3-O-methyl-D-glucose and 3H-2-deoxy-D-glucose) across the r...
A Rapid and Simple Method for Isolating Principal Cells from the Rat Caput Epididymidis
epididymis principal cell rapid isolation
2009/2/19
A technique is described for the rapid isolation of principal cells from enzymatically dispersed rat caput epididymidis by differential sedimentation into calf serum. Sedimentations were prepared in...
Pituitary adenylate cyclase-activating polypeptide（PACAP）：effects on blood flow in the testis and caput epididymidis of the rat
blood flow testis caput epididymidis rat
2009/2/18
Pituitary adenylate cyclase-activating polypeptide (PACAP) is synthesized in developing germ cells in the testis and may act as a paracrine modulator of spermatogenesis and/or participate in tubul...
Obstruction of the vas deferens alters protein secretion by the rat caput epididymidal epithelium in vivo
protein secretion rat caput epididymidal epithelium
2009/2/18
Obstruction of epididymal lumen fluid flow alters the intraluminal environment and potentially changes epididymal epithelial cell function when those functions are dependent on intraluminal regulato...
Comparative study of boar sperm coming from the caput, corpus, and cauda regions of the epididymis
boar sperm caput corpus cauda regions epididymis
2009/2/13
Sperm quality in the caput, corpus, and cauda regions of the epididymis of healthy and sexually mature Landrace boars was studied. Epididymal sperm characteristics were examined by light microscopy (L...
Postvasectomy alterations in protein synthesis and secretion in the rat caput epididymidis are not repaired after vasovasostomy
Postvasectomy alterations protein synthesis secretion rat caput epididymidis vasovasostomy
2008/12/25
Many men who have undergone vasectomy later request vasovasostomy. Unfortunately, significant numbers of these men remain infertile despite the reestablishment of patent ducts. This report examine...

5-hydroxytryptamine tryptophan hydroxylase neuroendocrine cells male reproduction serotonin receptor spermatozoa
2008/12/24
The caput epididymis of some mammals contains large quantities of serotonin whose origin, targets, and physiological variations have been poorly studied. We combined morphological and biochemical...
The Contractile Wall of the Caput Epididymidis in Men Affected by Congenital or Postinflammatory Obstructive Azoospermia
Congenital absence of vas deferens human caput epididymidis smooth muscle cell
2008/12/22
The transport and storage of spermatozoa in the epididymis depend on the contractile activity of its tubular wall. It is not known what differences exist in the contractile wall of the human epidi...
