Effect of Neem Oil on Sperm Mitochondrial Activity
Normozoospermia Neem Oil Sperm Mitochondrial Activity
2015/7/15
It is a known fact that neem oil has some effect on motility of sperm. Motility of sperm depends on mitochondrial activity present in mid-piece of sperm. In the present study, the mitochondrial activi...
Human sperm mitochondrial function related to motility：a flow and image cytometric assessment
Human sperm mitochondrial function motility cytometric assessment
2009/2/23
Current evaluation of male fertility, routinely estimated by sperm count, motility, and morphology, provides only crude information about the fertility state of individuals. Both flow and image cyto...
The automated analysis of rat sperm motility following subchronic epichlorohydrin administration：methodologic and statistical considerations
rat sperm motility subchronic epichlorohydrin administration methodologic and statistical considerations
2009/2/23
The automated analysis of sperm motion endpoints is potentially useful in identifying male reproductive toxicants and ultimately in predicting fertility in humans. The present study was designed to ...
The effect of tumor necrosis factor on human sperm motility in vitro
tumor necrosis factor human sperm motility
2009/2/23
Tumor necrosis factor (TNF alpha) is present in elevated levels in peritoneal fluid from infertile women with endometriosis. The effect of TNF alpha on human sperm motility in vitro was evaluated ...
Synchronous assay for human sperm capacitation and the acrosome reaction
human sperm capacitation acrosome reaction
2009/2/23
A synchronous acrosome reaction system was established for human spermatozoa. Seminal plasma is removed from the spermatozoa by centrifugation and the washed spermatozoa are capacitated in a modif...
Analysis of the relationship between defective sperm function and the generation of reactive oxygen species in cases of oligozoospermia
defective sperm function reactive oxygen species oligozoospermia
2009/2/23
The ability of human spermatozoa to exhibit sperm-oocyte fusion in response to the ionophore, A23187, was examined in relation to the capacity of these cells to generate reactive oxygen species. I...
Relationship between the results of sperm analysis and GIFT
Relationship sperm analysis GIFT
2009/2/23
In vitro fertilization (IVF) and GIFT have been proposed as therapeutic approaches in infertile couples where a significant male factor is present. To date, few published data are available relati...
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...
Indomethacin and oxaprozin lower seminal prostaglandin levels but do not influence sperm motion characteristics and serum hormones of young healthy men in a placebo-controlled double-blind trial
seminal prostaglandin levels sperm motion characteristics serum hormones young healthy men
2009/2/23
To evaluate the influence of indomethacin and oxaprozin on reproductive function in healthy young men, 34 volunteers with normal semen parameters were recruited. In a randomized double-blind design,...
