Since the quality of sperm is affected by water industrial or agriculture pollution, sperm motility was measured as a sensitive and accurate bioindicator of water quality. In this study, sperm motility was measured by a computer assisted sperm analysis after 24 hours exposure of sperm to different concentration of heavy metals) Cadmium and Zinc). The results show that the sperm motility was not...

Sperm competition is thought to be a major force driving the evolution of sperm shape and function. However, previous studies investigating the relationship between the risk of sperm competition and sperm morphometry revealed inconclusive results and marked differences between taxonomic groups. In a comparative study of two families of passerines (Fringillidae and Sylviidae) and also across spe...

BACKGROUND This prospective study compared the acrosome reaction following ionophore challenge (ARIC) versus conventional sperm parameters and sperm velocities in predicting successful outcome following ovarian stimulation and intrauterine insemination. METHODS All patients were offered a maximum of three treatment cycles. Conventional semen analysis was performed and sperm velocities were me...

evidence suggests that human sperm chromatin anomalies adversely affect reproductive outcomes and infertile men possess substantially amount of sperm with chromatin anomalies than fertile men. routine semen analysis evaluates parameters such as sperm motility and morphology, but does not examine the nuclear dna integrity of spermatozoa. it has been suggested that altered nuclear chromatin struc...

OBJECTIVE Several publications have established a relationship between sperm DNA damage and male factor infertility, based on data from America, Europe, and Asia. This study aimed to compare the extent of sperm DNA damage in sperm samples from Nigerian men with unexplained infertility and in sperm samples from a fertile group composed of sperm donors who had successfully impregnated a female pa...

BACKGROUND Sperm proteins are important for the sperm cell function in fertilization. Some of them are involved in the binding of sperm to the egg. We characterized the acrosomal sperm protein detected by a monoclonal antibody (MoAb) (Hs-8) that was prepared in our laboratory by immunization of BALB/c mice with human ejaculated sperms and we tested the possible role of this protein in the bindi...

After twenty years Computer Aided Sperm Analysis has developed considerably and is now routinely used in many laboratories across the world. The advantage of the CASA methodology available is twofold: Analysis of particularly sperm concentration, sperm motility, sperm morphology and vitality is quantified in an Background manner. Secondly, most of the CASA analysis with the exception of sperm m...

objective: this study aims to evaluate the protective effects of american ginseng administered by gastric intubation on sperm vital quality in adult male rats treated with cyclophosphamide (cp). materials and methods: in this experimental study, 28 adult male wistar rats were assigned to four groups, seven rats in each. the animals allocated to control, cp treated, ginseng treated and cp-ginsen...
