In azoospermic infertile men with varicocele, testicular biopsy revealed histopathologic patterns that varied from disorganized spermatogenesis with low or moderate sperm scores to early (primary spermatocytes stage) or late (spermatid stage) arrested spermatogenesis or germ cell aplasia and Sertoli cells only. Diagnostic testicular biopsy can be helpful for accurate management of azoospermic i...

OBJECTIVE In sever oligospermia; one of the paths used for surgical sperm retrieval (SSR) is to extract sperm via a testicular biopsy. The aim of our study is to determine the reliable time interval between testicular biopsy and intracytoplasmic sperm injection (ICSI) procedure in order to obtain optimumsperm parameters (count, motility and normal morphology). MATERIALS AND METHODS This cohor...

Background: The evaluation of the infertile male includes a thorough history taking, physical examination Semen analysis, hormonal array and search for anti sperm antibody. Additional tests include Trans rectal ultrasound, vasography and testicular biopsy. The latter is particularly useful in cases of azoospermia or oligozoospermia and normal endocrine function. Objective: To identify and categ...

OBJECTIVE To assess the effects of two methods of freezing on testicular sperm DNA from subjects with obstructive azoospermia and to compare these with samples of fresh and freeze-thawed testicular sperm from fertile men. DESIGN The Comet assay was used to determine the percentage of undamaged DNA in fresh testicular sperm, testicular sperm freeze-thawed in suspension and in a biopsy sample (...

AIM To evaluate whether inhibin-B can predict the outcome of a microsurgical epidymal sperm aspiration (MESA) procedure in patients with suspected primary obstructive azoospermia (OA) and if inhibin-B can replace testicular biopsy in the diagnostic work-up of these patients. METHODS Inhibin-B levels and testicular biopsy scores were related to the outcome of MESA in 43 patients with suspected...

A case report of a 78-year-old gentleman presented with scrotal mass mimicking testicular tumor on ultrasonographic examination. Excisional biopsy proven xanthogranulomatous orchitis which is rare condition. The clinical presentation, radiological findings and management will be discussed.

A case of a 45,X/46,XY boy with gonadal dysgenesis is presented. The patient showed hypospadias and right undescended testis. He underwent underwent repair surgery for hypospadias, right orchidopexy, and bilateral testicular biopsy. Testicular biopsy revealed no malignant finding. He was followed-up annually by scrotum palpation. When the patient grew up to 24 years old, he was diagnosed to hav...

Objective To investigate effects of cryopreservation on changes of the ultrastructure of human testicular sperm and evaluate the efficacy of cryopreserving testicular tissue as a source of sperm for assisted reproduction. Methods Testicular biopsy tissues were obtained from infertile patients (n=12) with obstructive azoospermia and cryopreserved. Testicular sperm motility was observed after in ...

Men with congenital absence or bilateral partial aplasia of vas deferens, or those with failed or surgically unreconstructable obstructions or azospermic men with testicular failure or genetic cause can now be treated by using sperm retrieval techniques in conjunction with in vitro fertilization/intra cytoplasmic sperm injection (ICSI/ IVF). These techniques are: Microsurgical epididymal sperm ...

Background & objective: Regarding the importance of histologic examination of testicular biopsy for clinical planning of infertility, the current study was conducted to compare 2 separate histologic examination of testicular biopsy. Also, some cases with known fertility outcome were followed and their histological patterns were also compared with those of the outcome. ...
