Granulosa cell tumor of the testis is an infrequent stromal cell tumor that can be distinguished into adult and juvenile, the latter being more common. Juvenile granulosa cell tumor of the testis is a rare pathologic finding, accounting for 1.2%-3.9% of prepubertal testicular tumors. It is considered as a benign stromal sex cord tumor and is usually unilateral. Although radical surgery was prev...

A 22-year-old male presented at our institution with an incidentally ultrasound-detected testicular tumor. Magnetic resonance imaging showed a contrast-enhanced right intratesticular mass over 1 cm in size. The patient underwent testis sparing surgery. Pathologic examination revealed seminoma. A follow-up nine months later showed no residual tumor, a normal contour of the testis and no evidence...

Cystic dysplasia of the testis is a rare, benign pathologic finding. We present two recent cases of cystic dysplasia of the testis to our practice. The first case involves an 11 month old male presenting with a non-palpable, intra-abdominal left testis. The second case involves a 7 year old male with left scrotal swelling and a history of left renal agenesis. After review of the literature, the...

Figure 1 a. Longitudinal US image of the right testis show a bilobulated mass in the upper medial aspect of the testis. The mass had sharp margins, composed of a central echogenic area and of alternating hyperechogenic and hypoechogenic rings in the periphery (onionskin sign), measuring 2.4 x 1.7 x 1.7 cm. b. Longitudinal Doppler-US image of the right testis demonstrates the absence of vascular...

background: cytotoxic therapy can lead to prolonged azoospermia or even sterility. in the present study, we investigated the morphological changes of mouse testes after gamma-radiation. methods: after anaesthetizing of nmri mice, testes and their surrounding tissues were irradiated using a cobalt therapy machine. four experimental groups were irradiated with fractionated doses of: 1.5+8, 1.5+12...

background: advancement in the treatment of various types of cancer has led to greater patient survival. these treatments essentially have toxic effects on different kinds of cells, such as germ cells. infertility as one of the side effects of cancer treatment has changed the quality of life of young cancer survivors dramatically. melatonin is an antioxidant with receptors in the reproductive s...

CASE REPORT A 19-year-old man presented to our outpatient clinic with a perineal mass and discomfort. Examination showed an empty and poorly developed left hemiscrotum. The contralateral testis was in its normal location in the right hemiscrotum (Figure 1). An oval-shaped soft mass was detected in the perineum measuring 4 × 5 × 6 cm. A clinical diagnosis of perineal ectopic testis was made. We ...

The distribution of XX and XY cells in XX----XY chimaeric mouse testes was analysed by enzyme marker analysis of separated testicular tissues and by in situ DNA marker analysis of air-dried testicular cells and testis sections. XX cells contributed to the Leydig cells, the peritubular cells and the vascularized connective tissue of the tunica albuginea. The Sertoli cells, on the other hand, app...

Administration of Gonadotrophin releasing hormone (GnRH) to male C versicolor during nonbreeding season increases the weight of testis;diameter of testis, seminiferous tubule, Sertoli and Leydig cell nuclei. It also activates the spermatogenic process. Increase in the weight of epididymis and lowered cholesterol level of testis indicate androgen production. Treatment of tesotsterone along with ...

Ovaries are paired pelvic organs located on thesides of the uterus. Although it is rare in general population, between age group 20-40 years males,Testicular germ cell neoplasms most common form malignant tumour reported. In young women ovarian tumours rank second among tumors and males, testicular tumorsserves as leading percentage all seen early late adulthood (3rd 4th decade) life. The peopl...
