The abnormal sperm motility group was treated with PSA. Results: The PSA concentration was(1.34±0.63)mg/ml in normal sperm viscosity group,(0.69±0.31)mg/ml in abnormal sperm viscosity group; there were significant difference(P<0.01).
There was significantly negative correlation between PLA2 content in seminal plasma and sperm density( r =- 0.602 , P < 0.05 ), while there was insignificant correlation between PLA2 and sperm motility or percentage of motility.
Results MTCYB deletion in spermatozoa was observed in 16 of the 100 infertile males,9 being in the infertile males with poor sperm motility and 7 in the normoal motility group( P >0 05).

Besides, TNF-α contents in subjects with lower sperm activity and less motility rate as well as IL-8 contents in subjects with less sperm motility rate were both significantly higher than those in subjects with more normal sperms ( p<0 01, p<0 05 ).
The sperm activity and motile ratio, hypoosmotic swelling test (HOS) and sperm penetration in capillary in 4 h, 8 h, 16 h and 24 h after infectionwith UU.

The culture of UU , the inspection of the clinical symptoms, the determination of the PH and the norm of WBC in prostatic fluid ,as well as Lecithin Corpuscle, sperm activity, sperm survival rate were carried out respectively before and after treatment.
The content of IGF-1 in seminal plasma was significantly lower in the group of decreased spermatic function than those in the group of normal spermatic function(P<0.01),using the motility of sperm and the rate of movable sperm to evaluate the spermatic function.
As compared with 10 control rats, the sperm density in testis rete fluid of the treated rats declined to 7% and the motility of sperm from epididymus cauda reduced to 6%. While the testosterone level in serum increased to 255%, the testosterone level in the rete fluid decreased to 50%.
The levels of IgG in the seminal plasma were significantly different between males with normal motility of sperm and males with abnormal motility of sperm,as well as between AsAb positive and AsAb negative(P<0.05).

Insufficient sperm motility and/or their unsuccessful capacitation result in poor if any fertilization.
This method is used for assessing the main parameters of sperm motility by means of a microscope and video camera connected to a computer with easily available software.

Recovery of Sperm Activity After Osmotic Shock in the Three-Spined Stickleback: Implications for Pre-Oviposition Ejaculation
Present results also suggest that EDL first induces impairment of Sertoli cells function and this leads to reduction of sperm activity and secretion of inhibins.
It seems that sperm activity is the most sensitive, and that fertilization and gastrulation are more sensitive than first cleavage, blastulation and pluteus formation.
We found no differences between sneakers and parentals in length and swimming speed of sperm, or percent and duration of sperm activity.
Here, we use computer-assisted sperm analysis (CASA) to examine changes in stickleback sperm motion over time in fresh water, showing for the first time that this reduction in motility can be reversed by an increase in osmolality.
Other sperm motion characteristics did not significantly differ between the two groups except for postthaw curvilinear velocity (P=0.01).
Louis, MO; salica-based) and the IxaPrep (Medicult, Copenhagen, Denmark; non-salica based, polysucrose medium) method, with respect to recovery of pregressive motile sperm and various sperm motion characteristics.
The microtubules determine the axis of the developing sperm; polarity is set by the direction of sperm motion and is homologous with most flagellate sperm in that the nuclear material is anterior and the microtubule initiating center is posterior.
Sperm motion analysis was performed at the same time.
According to results obtained, L-PGDS may have the ability to improve progressive motility of sperm, and L-PGDS in seminal plasma and on sperm surface may impact male fertility in the female reproductive tract.
The study of sperm obtained from epididymises of males did not reveal significant differences in both morphology and motility of sperm between males of the control and experimental groups.
The motility of sperm decreased remarkably in EDL rats compared with controls on 5 d after the operation.

Oral administration of the compound to adult male beagle dogs (50-246 mg/kg) or rhesus monkeys (85-100 mg/kg) was associated with a decline in motility of sperm in ejaculates obtained after dosing.
Spermatogenesis in the dog can be suppressed when the temperature of the testis is elevated to about 42±1℃ by means of a microwave diathermy unit.

The wave length is i2 cm with a maximum output of 0-200 watt. The output was adjusted to 10-15mw/cm~2 and as soon as the testicular temperature was raised to 42±1℃, it was kept constant for 20 minutes. A thermister clements for monitoring the temperature was used.The sperm ejected for analysis was collected by means of etectric stimulator per rectum within 3-5 minutes. The stimulation parameters were 20-30 Hz in frequency, 300 mA in current and 500-700mv in potential with continuous hand manipulation.4 dogs weighing 15±1 kg have been under observation. It showed that heat affects spermatogensis: (1) before heat trcatment sperm density (P<0.001); (2) The motility of sperm decreased gradually from the normal 7-8 cm (10.8cm individually) per 8 hours to 1cm per 8 hours (some were reduced to zero) in three months; (3) after heat treatment the survival rate of sp-erm was reduced from 92.70％ to 60.46％ in three months, (P<0.01).With only a single microwave irradiation, various rates of reduction of sperm production, sperm motility and sperm survival were obtained in 3-5 months in different dogs. This study offers the possibility of a means of producing reversible and irreversible sterility in human males, without surgical or pharmacological procedures.
Induction of possible male sterility in laboratory rats by gossypol was examined by microscopic observations on sperm motility, sperm morphology following silver staining, and meiosis. The rats were force-fed with gossypol acetate once with 400mg/kg body weight. In a span of 2-5 weeks post-feeding, a marked reduction of sperm motility was observed with a concurrent increase of abnormal spermatozoa Silver staining of the spermatozoa showed various tail abnormalities, including disrupted connecting piece, bent...
Induction of possible male sterility in laboratory rats by gossypol was examined by microscopic observations on sperm motility, sperm morphology following silver staining, and meiosis. The rats were force-fed with gossypol acetate once with 400mg/kg body weight. In a span of 2-5 weeks post-feeding, a marked reduction of sperm motility was observed with a concurrent increase of abnormal spermatozoa Silver staining of the spermatozoa showed various tail abnormalities, including disrupted connecting piece, bent tails, looped tails, and cracked midpiece, Sperm head structure appeared to be not affected. Beginning 6 weeks post-feeding, there was a complete recovery. Short-term in vitro experiments showed similar but weaker response. In all samples, histologieal sections and cytogenetic preparations of testes revealed no abnormalities in the activity and normally of meiotic divisions. In animals 2-4 weeks after feeding with gossypol, no argentophilic accessary structures in developing mammalian spermatids were observed.
In the study of male contraception, much importance is attached to the obseryation on the density, survival ratio and motility of the spermatozoa in the semen. In experimental studies in the animals, however, certain difficulties are encountered in collection of the animal semen specimens at regular intervals. This paper describes an apparatus and the methods used for regular collection of guinea-pig and rat semen by an electroejaculation .technique, practical application of the method is anticipated
