Testicular function and future fertility may be affected by cancer treatment during childhood. Whilst survival of the germ (stem) cells is critical for ensuring the potential for fertility in these patients, the somatic cell populations also play a crucial role in providing a suitable environment to support germ cell maintenance and subsequent development. Regulation of the spermatogonial germ-...

Background: More than a decade work in preservation of male fertility by spermatogonial stem cell (SSC) transplantation in animal models as well as new discoveries about the nature of human SSCs has prompted an investigation into the possibility of an effective clinicalgrade procedure for isolation and cryopreservation of human testicular cells. Materials and Methods: Clinical-grade reagents, v...

Testicular cancer is a malignancy that impacts young men worldwide. The modern treatment of testicular has evolved due to innovations in medical approaches and surgical techniques. retroperitoneal lymph node dissection (RPLND) an integral component the cancer. We aim highlight advances oncologic considerations noted over past century. Once recognized as highly morbid procedure, understanding an...

Cadmium (Cd) is a reproductive toxicant that induces germ cell apoptosis in the testes. Previous studies have demonstrated that endoplasmic reticulum (ER) stress is involved in Cd-induced germ cell apoptosis. The aim of the present study was to investigate the effects of N-acetylcysteine (NAC), an antioxidant, on Cd-induced ER stress and germ cell apoptosis in the testes. Male CD-1 mice were in...

This case report describes for the first time a case of pure testicular carcinoid pre-aortic lymph node metastases in a 25 year old patient with carcinoid syndrome. The simultaneous occurrence of intratubular germ cell neoplasia in the surrounding testicular tissue was identified by OCT4 and placental-like alkaline phosphatase positivity. This confirmed that the tumour had a germ cell origin in...

AIM To evaluate the immunohistopathological changes in the contralateral testis of rats after an experimental spermatic cord torsion. METHODS Male Sprague-Dawley rats of 45-50 days old were subjected to a 720 degree unilateral spermatic cord torsion for 10, 30 and 80 days (experimental group, E), respectively or sham operation (control group, C). Histopathology of the contralateral testis as ...

Testicular injuries like torsion or cryptorchidism can cause massive germ cell death, which could have great impact on male reproductive health. In addition, it has been proposed that modern life style, in the form of underwear or sedentary work position, could increase the testicular temperature, induce germ cell apoptosis, reduce spermatozoa quality and promote male infertility. In this work ...

Early stage testicular germ cell tumors are highly curable malignancies, but the need for close radiologic and biomarker surveillance is pivotal. Even in the setting of recurrence, rescue therapy has been successfully implemented. The present report describes a patient that had rapid and aggressive recurrence after radical orchiectomy for a testicular germ cell tumor and presented with bulky di...

In testicular germ cell tumour (GCT), imaging plays a central role in assessment of tumour bulk, sites of metastases, monitoring response to therapy, surgical planning and accurate assessment of disease at relapse. The primary modality used for imaging patients with GCT is computed tomography (CT) but plain film radiography, ultrasound, magnetic resonance imaging (MRI) and positron emission tom...
