Meaning and Definition

A specialised cell in the testes, located between the seminiferous tubules, responsible for producing and secreting the male hormone testosterone.

In endocrinology and reproductive biology, it refers to the primary androgen-producing cells in males. Dysfunction can lead to conditions like hypogonadism. Analogous testosterone-producing cells exist in other species and in ovarian tissue (theca cells).

Dialectal Variation

Common Mistakes When Using “leydig cell”

  • Mispronunciation: /ˈleɪdɪɡ/ or /ˈliːdɪɡ/ instead of /ˈlaɪdɪɡ/.
  • Misspelling: 'Leydig' as 'Leydigg', 'Leidig', or 'Lydig'.
  • Conceptual: Confusing Leydig cells with Sertoli cells or with the cells of the adrenal gland that also produce androgens.

FAQ

Frequently Asked Questions

They were first described in 1850 by the German anatomist Franz von Leydig.

Primarily, yes. They are the main testosterone-producing cells in the male testes. However, analogous cells exist in the ovaries of females (theca cells) and in other tissues in smaller amounts.

Damage or dysfunction of Leydig cells leads to reduced testosterone production, a condition known as hypogonadism. This can result in symptoms like low libido, infertility, fatigue, and loss of muscle mass.

Most Leydig cell tumours are benign (non-cancerous) and are often discovered incidentally. However, a small percentage can be malignant, especially in older men.

A specialised cell in the testes, located between the seminiferous tubules, responsible for producing and secreting the male hormone testosterone.

Leydig cell is usually technical/scientific (biology, medicine, endocrinology) in register.

Leydig cell: in British English it is pronounced /ˈlaɪdɪɡ ˌsel/, and in American English it is pronounced /ˈlaɪdɪɡ ˌsɛl/. Tap the audio buttons above to hear it.

Learning

Memory Aids

Mnemonic

Think: 'Ley' sounds like 'lie' – men lie down? Not helpful. Better: 'Leydig cells LOYALLY deliver testosterone.' Link the 'Ley' sound to 'Loyal' for function.

Conceptual Metaphor

THE TESTIS AS A FACTORY: Leydig cells are the hormone production units. THE BODY AS AN ECOSYSTEM: Leydig cells are a keystone species for male development.
