Fructolysis in Human Spermatozoa Under Normal and Pathological Conditions
human spermatozoa motility anaerobic fructolysis lactic acid production
2009/2/18
Anaerobic fructolysis was studied in human spermatozoa from 1) normal, 2) oligospermic, and 3) necrospermic semen, as well as 4) in normal spermatozoa irreversibly immobilized with a spermicidal a...
Expression of clusterin/sulfated glycoprotein-2 under conditions of heat stress in rat Sertoli cells and a mouse Sertoli cell line
SGP-2 testis HSP7O
2009/2/17
Clusterin is the major protein produced by rat Sertoli cells and is deposited onto sperm membranes; however, its function is unknown. In order to gain insight into the regulation of clusterin in Serto...
Choice of operating conditions to minimize sperm subpopulation sampling bias in the assessment of boar semen by computer-assisted semen analysis
CASA computer semen analysis tracking semen
2009/2/16
The performance of a computer-assisted semen analysis system was evaluated for use with washed boar spermatozoa. Accuracy was tested using a computer graphics-generated series of spots moving along ...
Development of computer-directed methods for the identification of hyperactivated motion using motion patterns developed by rabbit sperm during incubation under capacitation conditions
computer-directed methods identification hyperactivated motion motion patterns rabbit sperm
2009/2/12
Rabbit spermatozoa developed motions that mimicked hyperactivated motility during incubation for 16-20 hours under capacitation conditions and in several other commonly used media. Sperm from some rab...
The aim of this study was to determine the differences in motility of frozen and thawed bull spermatozoa under conditions of weightlessness compared with ground conditions. The tests were performe...
Kinematics of human spermatozoa incubated under capacitating conditions
motility hyperactivation videomicrography
2009/2/6
Suspensions of seminal plasma-free human spermatozoa were prepared by swim-up from semen and studied using high magnification videomicrography after incubation under capacitating conditions for 1.5-...
Effect of different incubation conditions on phosphatidylserine externalization and motion parameters of purified fractions of highly motile human spermatozoa
Motility incubation phosphatidylserine translocation
2008/12/30
The objective of this study was to assess the temporal effects of sperm incubation at body temperature with various amounts of human serum albumin (HSA) on motion parameters and phosphatidylserine e...
Sonographic testicular microlithiasis as an indicator of premalignant conditions in normal and infertile men
Carcinoma in situ echogenic foci infertility testicular
2008/12/29
Sonographic detection of multiple, small hyperechogenic lesions in the testis (testicular microlithiasis; TM) can indicate germ cell tumors. However, it has not been well established whether this ...
Evaluation of Chromosome Breakage and DNA Integrity in Sperm：An Investigation of Remote Semen Collection Conditions
Snap-freezing sperm-FISH TUNEL neutral comet assay
2008/12/19
Collection of ejaculated semen at a remote site (outside of the laboratory) would facilitate participation rates and geographic diversity in reproductive epidemiology studies. Our study addressed ...
Inflammatory Conditions of the Male Excurrent Ductal System. Part II.
Inflammatory Conditions Male Excurrent Ductal System
2008/12/4
In Part I of the review, we discussed epididymitis, a commonly encountered clinical entity, and the rarely described efferent ductule inflammation. In Part II of the review, we focus on another rarely...
Inflammatory Conditions of the Male Excurrent Ductal System. Part I.
Inflammatory Conditions Male Excurrent Ductal System
2008/12/4
Physiologically, the endocrinologic interplay between testes and pituitary gland results in the production of spermatozoa. Before serving their role in fertilizing oocytes, spermatozoa must exit the t...
