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 ...
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 ...
A sperm motility inhibitor from human seminal plasma was purified and characterized. The purification procedure includes dialysis, ion exchange chromatography on SP-Sephadex C-25 and adsorption chro...
Quantitative methods for the determination of the concentration, percent motility and swimming speed of human and animal spermatozoa can assist in the objective analysis of sperm and semen quality. ...
The number of bovine spermatozoa separated in a swim-up procedure was quantified using an electronic cell counter. In an initial test of the swim-up procedure, non-frozen sperm samples with differen...
The presence of motility inhibitors in seminal plasma and within spermatozoa from control and infertile men with poor sperm motility was investigated using demembranated reactivated human spermatozo...
An in vitro study was designed using the laser light-scattering technique to obtain further information on the dose-effect relationship of methylmercury on sperm motility. The technique provided a q...
The absorption of L-carnitine from the duct of the proximal regions of the rat epididymis was investigated using a stopped-flow, split-droplet microperfusion technique. L-carnitine was absorbed from...
A quantitative method is described for distinguishing two types of mouse sperm motility using a new parameter, the Linear Index. One hundred spermatozoa from C57BL/6-+/+ and 100 spermatozoa from C57...
This study evaluates the reversibility of the effects of gossypol on testicular ultrastructure and the motility of epididymal spermatozoa. Adult male rats were treated 6 days weekly with the vehic...
A series of semen samples that had been recorded on motion picture film, then evaluated via standard visual techniques by a number of well established fertility clinics (Van Duijn et al (1971)), w...
The reproductive system of male obese Zucker rats was studied to determine whether there are abnormalities in testis composition, organ weights, or sperm motility, which might contribute to their se...
Hormonal male contraception requires an induction phase before azoospermia and contraceptive safety are achieved. The nature of spermatozoa that may be ejaculated during this induction phase was s...
The effects of nitric oxide (NO) on sperm motility were examined in the fathead minnow, Pimephelas promelas, using computer-assisted sperm analysis (CASA). The observed effects underscore the dual n...
Hst7, a mouse hybrid sterility locus, has been mapped in close linkage to four other hybrid sterility loci, on proximal chromosome 17 within the t complex. When an allele (s) of Hst7 from the specie...
