Evaluation of computerized analysis of sperm movement characteristics and differential sperm tail swelling patterns in predicting human sperm in vitro fertilizing capacity
sperm movement characteristics differential sperm tail predicting human sperm
2009/2/23
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...
Relationship between rapid eye movement sleep and testosterone secretion in normal men
Luteinizing hormone follicle-stimulating hormone
2009/2/18
The relation between the pituitary-gonadal hormones' rhythm and sleep physiology in men is not fully elucidated. To examine whether the reproductive hormones are correlated with sleep architecture, ...
Testicular capillary permeability：the movement of luteinizing hormone from the vascular to the interstitial compartment
UI vascular permeability testis rat
2009/2/13
It has previously been shown in several species that pulses of luteinizing hormone (LH) in peripheral serum are followed within 10-20 minutes by pulses of testosterone. Whether or not LH pulses di...
The immunohistochemical localization of alpha 2-macroglobulin in rat testes is consistent with its role in germ cell movement and spermiation
immunohistochemical localization alpha 2-macroglobulin rat testes
2009/2/13
alpha 2-Macroglobulin (alpha 2-MG) is a nonspecific protease inhibitor and binding protein for peptide hormones that was recently isolated from Sertoli cell-enriched culture medium and shown to be t...
Effect of follicular or oviductal fluids on movement characteristics of bovine sperm during capacitation in vitro
Sperm motion analysis motility hyperactivation
2009/2/12
Mammalian sperm exhibit characteristic motility changes associated with capacitation. Movement characteristics of bovine sperm incubated in noncapacitating (control, medium alone), capacitating (ovidu...
Movement characteristics of boar sperm obtained from the oviduct or hyperactivated in vitro
Pig uterine tube fallopian tube sperm motility
2009/2/10
The objectives of this study were to describe hyperactivated motility in boar sperm and to determine the incidence of hyperactivation among boar sperm flushed from the oviduct. Oviducts were surgica...
Fluid movement in the lumen of the rat epididymis：effect of vasectomy and subsequent vasovasostomy
vasovasostomy vasectomy epididymis fluid movement
2009/2/6
Intraluminal fluid movement rate was measured in four regions of the rat epididymis. The fastest flow occurred in the proximal caput epididymis (18.5 +/- 3.7 mm/hour) and the slowest in the distal...
