Background: Zinc is essential for the normal functioning of male reproductive system. The data on diagnostic value zinc level in human spermoplasm and its relationship with main parameters sperm fertility are contradictory.
 Aim: study correlations between spermogram characteristics.
 Methods: men age (n=486, average 33.073.03 years) was studied. In addition to standard spermogram, MA...

Background: A high level of sperm chromatin decondensation results in loss DNA quality and it is associated with poor embryonic prognosis Assisted Reproductive Technology (ART). This had lead to introduction compaction testing assessment clinical male infertility. Toluidine blue assay one most commonly used tests measure research studies also routine use. So the objective our study was assess b...

orofacial clefts, including cleft lip with or without cleft palate (cl (p)), are common congenital malformations, second only to clubfoot in frequency of occurrence. the epidemiology and genetics of this disorder have been studied extensively in various countries by several investigators. the objective of this study is to assess the epidemiology and some genetic aspects of orofacial clefting at...

The androgen receptor (AR) is a protein encoded by the AR gene, which when mutated may affect spermatogenesis, the process in which spermatozoa are produced; thus, AR mutations could lead to male infertility. We examined exon 1 of the AR gene in men with idiopathic infertility. Blood or semen samples from 111 infertile, oligozoospermic (N = 31), asthenozoospermic (N = 23), teratozoospermic (N =...

heat stress (hs) often blamed for suboptimal reproductive efficiency and is a worldwide problem, which inflicts heavy economic losses reflected in limiting the breeding season of rabbits to be normally from september to may in northern hemisphere and subtropical regions. the present experiment was conducted to study the effect of summer heat stress and the alleviating effect of some antioxidant...
