-Cigarette smoking prevalence is still increasing in the developing world especially among men mainly in central Asia, east Europe and Africa. Furthermore, maternal cigarette smoking during pregnancy has multiple deleterious effects on the offspring, which may persist into adulthood. The present study was done to evaluate the pituitary-testicular activities of rats subjected to chronic nicotine...

abstract background: sperm cells extracted from testes (tese) have poor chromatin quality and motility. various substances are used in the laboratory to increase sperm motility and improve the art outcomes; however, there are few research which considered improving both sperm motility and chromatin quality. objective: the aim of this investigation was to evaluate the improvement of the testicul...

Different methods for recovering epididymal or testicular spermatozoa have been described and each has its drawbacks and advantages. Percutaneous aspiration of the testis may be the method of choice in cases of irreparable obstructive azoospermia. Using a 21-gauge needle, spermatozoa may be recovered in 96 % of patients. More patients undergoing fine-needle aspiration experienced less pain than...

objective: the main objective of the current study was to observe the ameliorative effect of withania somnifera on arsenic-induced testicular toxicity by exploring the crucial parameters such as sperm counts, sperm motility, hormonal assay and lipid peroxidation including histopathology. materials and methods: in the present study, arsenic in the form of sodium arsenite was administered orally ...

Spermatozoa retrieved from the testis of men with high levels of sperm DNA fragmentation (SDF) in the neat semen tend to have better DNA quality. Given the negative impact of SDF on the outcomes of Assisted Reproductive Technology (ART), an increased interest has emerged about the use of testicular sperm for intracytoplasmic sperm injection (Testi-ICSI). In this article, we used a SWOT (strengt...

Chlorpirifos (CPF) is a widely used organophosphate insecticide for both agricultural and domestic purposes with attendant human exposures. Many authors have documented the toxic effects of CPF on the central nervous system. This study was designed to study the effect of CPF and the influence of coadministration of ascorbic acid (AA) on the testicular functions of albino rats. Twenty five 2 mon...

This paper describes an unusual association of aspermia and untreatable, chronic testicular pain in a young man who underwent 14 surgical interventions for an imperforate anus. Physical examination and ultrasonography revealed left epididymal and vas enlargement, normal-sized testes, tubular ectasia of the left rete testis and a small intraprostatic paramedian left cyst. Retrograde ejaculation ...

Objective: To analyze the causes, clinical features and t r ea tment ou tcomes in pa t i en t s w i th nonobstructive azoospermia (NOA) and different severity of hypospermatogenesis (HS). Methods: This is a retrospective study from our reproductive clinic. Data of history, physical findings, serum hormone profiles and genetic studies were collected. The severity of HS was subdivided into three ...

Testicular sperm extraction is a common procedure used to find spermatogenic cells in men with nonobstructive azoospermia. The laboratory processing of biopsied testicular tissues needs to be performed meticulously to acquire a high yield of cells. In this study, the effectiveness of mincing the tissues after testicular biopsy was assessed using histological evaluation, as was the possible adve...
