Alternative to open testicular biopsy the fine needle aspiration cytology of the testis is being increasingly used as a minimally invasive method of evaluating testicular function. Aim of the study: To assess the diagnostic accuracy of fine needle aspiration cytology in...
متن کاملTesticular gene expression in cryptorchid boys at risk of azoospermia.
Despite timely and successful surgery, 32% of patients with bilateral and 10% with unilateral cryptorchidism will develop azoospermia. Cryptorchid boys at risk of azoospermia display a typical testicular histology of impaired mini-puberty at the time of the orchidopexy. During mini-puberty increased gonadotropin and testosterone secretion stimulate transformation of gonocytes into Ad spermatogo...
متن کاملdeletion and testicular expression of daz (deleted in azoospermia) gene in patients with non-obstructive azoospermia
background: deletions of the daz (deleted in azoospermia) genes within the human y chromosome's azfc region are the most common cause of spermatogenesis failure. these deletions are usually assessed by analyses of genomic dna extracted from peripheral leukocytes. daz genes are expressed in male germ cells. in this prospective study, we investigated daz expression and deletion in 102 consecutiv...
متن کاملTesticular fine needle aspiration cytology in azoospermic males.
One hundred one azoospermic males were subjected to fine needle aspiration cytology (FNAC) of the testis and 11 of them underwent testicular biopsy as well. In 99 cases, the aspiration was adequate for classifying into different categories, which are as follows: Sertoli cell only syndrome (46), normal spermatogenesis (27), hypospermatogenesis (10), tubular/peritubular sclerosis (10) and maturat...
متن کاملTesticular cytology of alpaca: comparison between impressed and smeared slides.
Testicular fine needle aspiration (TFNA) has proven to be a simple and minimally invasive procedure, which allows assessments of cytological parameters of seminiferous epithelium/tubules more accurately in a short time. Though this technique does not cause negative effects on sperm quality or any damage to testicular tissue, its use is very limited in male animal infertility diagnostics. Report...
