leydig cell

Noun A specialized interstitial cell found in the connective tissue surrounding the seminiferous tubules of the testes. Its primary function is the synthesis and secretion of the androgen hormone testosterone.
The term "Leydig cell" is used in biological, medical, and anatomical contexts to refer specifically to these testosterone-producing cells. It is always capitalized as it is an eponym, named after the German anatomist Franz Leydig who first described them.
- Under microscopic examination, the Leydig cells were clearly visible in the testicular tissue sample.
- The primary function of the Leydig cell is the production of testosterone.
- A disorder affecting Leydig cells can lead to reduced testosterone levels.
- Leydig cell tumor: A rare type of testicular tumor that originates from Leydig cells. It can be benign or malignant and may secrete hormones.
- The patient was diagnosed with a benign Leydig cell tumor.
- Interstitial cell of Leydig: A fuller, more descriptive synonym for Leydig cell.
- Leydig cell hyperplasia: A non-cancerous condition characterized by an increased number of Leydig cells.
- Leydig cell insufficiency: A condition where Leydig cells fail to produce adequate testosterone.
- Interstitial cell (of the testis)
- Interstitial cell of Leydig
The term "Leydig cell" has a single, specific meaning in anatomy and endocrinology. There are no common idiomatic or figurative uses for this term.
