AIM To estimate the prevalence of chromosomal abnormalities and Y chromosome microdeletion among men with azoospermia and severe oligozoospermia and its correlation with successful surgical sperm retrieval. SETTING AND DESIGN A prospective study in a tertiary level infertility unit. MATERIALS AND METHODS In a prospective observation study, men with azoospermia and severe oligozoospermia (co...

INTRODUCTION The aim of this study was to evaluate the effect of microsurgical subinguinal varicocelectomy on semen parameters in azoospermic men with clinical varicocele and to determine the predictive parameters of postoperative improvement. METHODS Twenty-three men with non-obstructive complete azoospermia and varicocele underwent subinguinal open microsurgical varicocele repair. The outco...

Controversial reports have been published about the influence of sperm source and of the underlying testicular pathology on success rates of intracytoplasmic sperm injection (ICSI). In this controlled study, ICSI treatment cycles with testicular spermatozoa from men with obstructive and non-obstructive azoospermia were compared with ICSI ejaculated sperm cycles with semen parameters < or = 5 x ...

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).&#x0D; Case: A patient 28 years old has a job as car paint worker. He came with chief complaint infe...

Over the past 20 years, there has been a clear trend to increase in number of infertile men Ukraine, their percentage reaches 50% couples. There is significant male infertility caused by azoospermia – lack sperm ejaculate. In infertility, found 10–15% patients, among other forms pathospermia. Given ambiguity ideas about etiology, pathogenesis and treatment diagnostic approaches for various type...

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: leydig cell tumor is a rare form of testicular neoplasm which comprises 1-3% of all testicular tumors and only about 3% of these tumors are bilateral. a few leydig all tumor have been described in patients with klinefelter�s syndrome so far. case: the patient described in this case report was a 24 year-old man with chief complaint of infertility for one year. physical examination, s...

Background: Azoospermia is the total absence of sperm cells from a patients semen sample after centrifugation. It could be obstructive or non-obstructive and its associated causes include chromosomal defects, infections, gonadotrophins imbalance, and etc in the patients. The objective is to determine the prevalence of primary testicular failure, germinal insufficiency, obstructive azoospermia a...
