An Unusual Case of Unilateral Malignant Leydig Cell Tumour of the Testis

Case Reports in Oncology, 2011
Leydig cell tumour is a benign testicular non-germ cell tumour, and malignant transformation is rare. We report a case of a 35-year-old man who came to our hospital with a painless left testicular mass measuring 1.2 × 1 cm. Histological evaluation of the

A giant testicular mixed germ cell tumour [PDF]

The Annals of The Royal College of Surgeons of England, 2016
We present a case that we believe to be the largest mixed germ cell testicular tumour reported in the United Kingdom. A 23-year-old male was admitted to our urology department with a large scrotal swelling. The patient was found to have a giant left testicular tumour and a solitary lung metastasis at presentation.

Effect of FSH on testicular morphology and spermatogenesis in gonadotrophin-deficient hypogonadal mice lacking androgen receptors [PDF]

, 2010
Follicle stimulating hormone (FSH) and androgen act to stimulate and maintain spermatogenesis. FSH acts directly on the Sertoli cells to stimulate germ cell number and acts indirectly to increase androgen production by the Leydig cells.

An Unusual Case of Primary Retroperitoneal Germ Cell Tumour in a Young Man

European Journal of Case Reports in Internal Medicine, 2018
Some 2–5% of germ cell tumours are of extragonadal origin, with a retroperitoneal location being very rare. The majority of retroperitoneal germ cell tumours have metastasized from a testicular tumour.

Androgen action via testicular arteriole smooth muscle cells is important for leydig cell function, vasomotion and testicular fluid dynamics [PDF]

, 2010
Regulation of blood flow through the testicular microvasculature by vasomotion is thought to be important for normal testis function as it regulates interstitial fluid (IF) dynamics which is an important intra-testicular transport medium.

Socio-economic inequalities in testicular cancer survival within two clinical studies. [PDF]

, 2012
BACKGROUND: Testicular cancer is the most common cancer in men under 35 years of age, and has the highest survival for adult male malignancies. Despite the fact that survival is very high, there is evidence that survival differs between socio-economic ...

Testicular development in mice lacking receptors for follicle stimulating hormone and androgen [PDF]

, 2012
Post-natal testicular development is dependent on gonadotrophin and androgen stimulation. Follicle stimulating hormone (FSH) acts through receptors (FSHR) on the Sertoli cell to stimulate spermatogenesis while androgens promote testis growth through ...
