Various procedures for sperm recovery in azoospermic men have been described, from open testicular biopsy to simple needle aspiration from the epididymis and the testis. Fifty-one obstructive and 86 non-obstructive azoospermic men were treated to compare the recovery of spermatozoa obtained by percutaneous aspiration from the epididymis (PESA) and aspiration/extraction from the testis (TESA, TE...
Obstructive azoospermia is a common cause of male infertility and can result from infection, congenital anomalies, or iatrogenic injury. Microsurgical vasal reconstruction is a suitable treatment for many cases of obstructive azoospermia, although some couples will require sperm retrieval paired with in-vitro fertilization. The various causes of obstructive azoospermia and recommended treatment...
Background: Around 10 % of infertile men and 1 percent all males have azoospermia. There are two types azoospermia, which obstructive non-obstructive Non-obstructive azoospermia's main mechanism is because the testes fail to produce sex hormone induce spermatogenesis (primary testicular failure).
 Case: A patient 28 years old has a job as car paint worker. He came with chief complaint infe...
background: about 10% to 15% of infertile men have azoospermia, which could be obstructive or non-obstructive. diagnostic biopsy from the testis and recently testicular sperm extraction (tese) are the most precise investigations in these patients. testicular biopsy can be done unilaterally or bilaterally. the worth of unilateral or bilateral testicular biopsy in men with azoospermia is controve...
background: the genetic association between cystic fibrosis transmembrane conductance regulator (cftr) gene mutations and male infertility due to congenital bilateral absence of vas deferens (cbavd) is well established. mutant cftr, however may also be involved in the etiology of male infertility in non-cbavd cases. the present study was conducted to estimate the frequency of δi507 and δf508 cf...
Factors other than spermatozoa could be the major determinant of the success of assisted reproduction treatment in cases of male infertility. Our aim was to evaluate the effect of the wife's age and ovarian reserve on assisted reproduction success rates in the most severe type of male infertility, i.e. azoospermia. A total of 249 consecutive couples suffering from male infertility caused by azo...
The introduction of the technique of intracytoplasmic sperm injection to achieve fertilization, especially using surgically retrieved testicular or epididymal sperm from men with obstructive or non-obstructive azoospermia, has revolutionized the field of assisted reproduction. The techniques for the retrieval of spermatozoa vary from relatively simple percutaneous sperm aspiration to open excis...
