Low sperm motility and physical and genetic issues in some instances, improving low sperm motility is unfortunately impossible if a genetic defect is the cause of low motility, there is no way to correct the issue through the use of supplements, medicines, or hormones. Some vaginal lubricants may damage sperm and astroglide, damaged sperm integrity and activity (motility) in laboratory tests but a fourth brand of vaginal lubricant, pre-seed, did not appear . Upon this classification, the normal sperm activity is diagnosed if more than 40 % of sperm cells demonstrate the motility of 1st and 2nd and 3rd grade (total sperm motility) plus there is more than 32 % sperm cells showing progressive motility (1st and 2nd grade).
Sperm motility inhibiting activity of a phytosterol from alstonia macrophylla wall ex a dc leaf extract: a tribal medicine debprasad chattopadhyay 1, sandhya r dungdung 2, kaushik das 2, sudipta saha 2, asit b mandal 3 &. Motility-inhibiting activity of me as well as the most active fraction b was estimated by evaluating forward motility (fm) of spermatozoa using hemocytometer as the counting chamber. The sperm motility inhibiting protein factor at 2 µg/ml (125 nm) level showed maximal motility-inhibiting activity the observation that the epididymal plasma factor lowered the intracellular camp level of spermatozoa in a concentration-dependent manner suggests that it may block the motility of caprine cauda spermatozoa by interfering the .
Abstract this study determined the effects of trichomonas vaginalis trophozoites, subcellular fractions, and medium from axenic t vaginalis cultures on human sperm motility and viability. Vanadium (iv) metallocene complexes having sperm motility inhibiting activity us09457247 expired - fee related us6500860b2 ( en ) 1998-01-20. The methanol extract (me) and the n-butanol fractions of methanolic extract of alstonia macrophylla wall ex a dc leaves were investigated on the forward motility (fm) of mammalian (goat and human) spermatozoa. Indian journal of experimental biology vol 43, november 2005, pp 1104-1109 sperm motility inhibiting activity of a phytosterol from alstonia macrophylla. T1 - clinically relevant enhancement of human sperm motility using compounds with reported phosphodiesterase inhibitor activity au - tardif,steve au - madamidola,oladipo.
Inhibition of human sperm motility by contraceptive anti-eppin antibodies from infertile male monkeys: effect on cyclic adenosine monophosphate protease activity . Sperm motility describes the ability of sperm to move properly through the female reproductive tract (internal fertilization) or through water (external fertilization) to reach the egg sperm motility can also be thought of as the quality , which is a factor in successful conception sperm that do not swim properly will not reach the egg in . Effects of selective serotonin reuptake inhibitors on sperm and male fertility in an animal study fluoxetine decreased spermatogenesis, sperm motility, and sperm . Effect of the protein kinase inhibitor h-89 on sperm motility and pka activity from control and cda activated sperm a , bovine caudal and caput sperm were incubated in buffer a in the presence or absence of 50 μ m cda and/or 50 μ m h-89.
Tukey–kramer test was used in conjunction with an anova to compare protease activities and the effects of protease inhibitors on sperm motility and velocity following tests of homogeneity of variance (levene’s test) and normal distribution of data (kolmogorov–smirnov’s test). Inhibition of human sperm motility by inhibitors of choline acetyltransferase b v sastry , v e janson and a k chaturvedi journal of pharmacology and experimental therapeutics february 1981, 216 (2) 378-384. The inhibitory activity of fraction b increases with increasing concentration in a dose-dependent manner phytochemical study of the extract revealed that the leaf contains tannins, flavonoids, sterols, triterpenes, alkaloids and reducing sugars.
The consequences of inhibiting 5a-reductase activity on steroid concentrations, gene expression, epididymal epithelial the compromised sperm motility and . These results indicate that sperm calcineurin activity is important during the later stages of spermatogenesis or during sperm maturation in the epididymis to elucidate where sperm calcineurin works, we administered csa or fk506 for short periods. Among the selective protein tyrosine kinase inhibitors, genistein was the most active and consistent, inhibiting sperm tyrosine kinase activity, py proteins, incidence of py sperm, and sperm motility and motion parameters, such as vel, alh, and hyperactivation. We demonstrate the presence and activity of pi 3-kinase in human spermatozoa and have investigated the molecular mechanism(s) by which the pi 3-kinase inhibitor, ly294002, triggers an increase in sperm motility.
