The discovery of adult Leydig cells by Franz Leydig in 1850 led to extensive research into the functions and regulation of this testis-specific cell type (1). In the early 1900s, Whitehead presented the first extensive analysis of fetal Leydig cells (FLCs) in pig embryos, staging the idea that a distinct Leydig cell population exists in fetal testes (2,

Leydig Cell in Idiopathic Varicocele
European Urology, 1990In a group of 31 patients with idiopathic varicocele (IV), testicular biopsy showed a decreased tubular diameter, hyperplasia in the number of Leydig's cells (LC; many with cytoplasmic vacuolization and atrophy) and a decrease in the number of positive LC in testicular tissue sections stained with the testosterone peroxidase-antiperoxidase method ...

This boy, age 3 years and 9 months, was referred for precocious puberty. He had pubarche 6 months prior to presentation. His genitalia had always seemed to be larger than his older brother’s genitalia; they had increased in size over the 4 to 6 months prior to presentation. He also had recent acceleration of growth in height.

We report on a 54-year-old male patient with Leydig cell tumor of testis, an incidental finding following orchiectomy for a testicular tumor. The pathological findings met the established histologic criteria for a benign tumor. The patient required no other treatment. The results of hormonal analyses were hormonal.

To describe a case of Leydig cell tumor of the testis, discuss the criteria for determining its benign or malignant nature and the clinical features according to patient age and the hormone profile.Scrotal US evaluation for an associated pathology incidentally detected a hypoechoic, homogeneous mass with preserved borders.

This review is about the study of the testis Leydig cells formation and development in prenatal and postnatal periods. Leydig cells of testis are the main place of synthesis and secretion of androgens including testosterone--the main male sexual hormone. Testosterone plays an important role in male reproduction regulation.
