 Purpose: To investigate the in vitro effects of methanol leaf extract E. hirta (MLEEH) on motility, viability and morphology caprine spermatozoa.
 Methods: The effect MLEEH treatment (1.25, 2.5, 5, 10 20 mg per mL) sperm percentage total progressive abnormalities were evaluated at 1, 5 min post-treatment. Sperm revival test was used to evaluate reversibility incapacitation following...
This study was designed to analyze boar sperm to compare motility, acrosome morphology, viability and ATP by various preservation methods between Duroc boar A with cold shock resistance sperm and Duroc boar B with cold shock sensitivity sperm. Semen volume, sperm concentration, motility and normal acrosome between Duroc boar A and B did not show any differences within 2 h after collection. Ther...
OBJECTIVE The aim of this study was to analyze the effect of myo-inositol in combination with minerals and vitamin on sperm motility in patients affected by asthenozoospermia as index of Bulgarian population. PATIENTS AND METHODS One-hundred-nine men aged between 18 and 50 years with reduced sperm motility identified by routine semen analysis were enrolled in this study. After excluding any u...
Postcopulatory sexual selection may select for male primary sexual characteristics like sperm morphology and sperm motility, through sperm competition or cryptic female choice. However, how such characteristics influence male fertilization success remains poorly understood. In this study, we investigate possible correlations between sperm characteristics and paternity success in the socially mo...
Background: Vitamin E is believed to be the primary component of the antioxidant system in spermatozoa. There is a relationship between activity of these antioxidant and function of sperm. Vitamins E and C which are belong to non-enzymatic antioxidant are used as a supplemented drug to improve sperm quality and male fertility. The present study was carried out to investigate the positive effect...
World's population is increasing at an alarming rate. Contraceptive methods for male are comparatively less common than female. Sperm motility, indicator fertilisation, regulated by a set of proteins protein phosphatase (PP) family. Among these PP1 directly related with sperm motility. SDS22 (suppressor Dis2 mutant 2) conserved and extensively expressed regulator, information regarding its func...
In the field of reproductive medicine, assessment of sperm motility is a key factor for achieving successful artificial insemination, in vitro fertilization, or intracellular sperm injection. In this study, the motility of boar sperms was estimated using real-time imaging via confocal microscopy. To confirm this confocal imaging method, flagellar beats and whiplash-like movement angles were com...
objective(s):althoughroutinely applied in assisted reproductive technology, human sperm cryopreservation is not a completely successful procedure. adverse effects of cryopreservation on the fertilization capacity, motility, morphology, and viability of spermatozoa have been proven; cryopreservation has also shown a role in sperm dna fragmentation and infertility. the post-thaw survival of sperm...
objective(s): increased levels of nitric oxide (no) in the testicular veins of people suffering from varicocele have already been reported. however, the role of no-synthase (nos) isozymes and their inhibitors have not been extensively studied. we aimed to evaluate the inhibitory effects of aminoguanidine (ag), on sperm motility, vitality, and mitochondrial membrane potential (mmp) in varicoceli...
introduction: tegrity is the most important component for transferring genetic information sperm dna fragmentation is considered a component of male infertility. its assessment comprises conventional semen analysis of which emphasis is placed on its evaluation in fertility clinics. in this study, we investigate the relationship between sperm parameters of motility, morphology, concentration, an...
