Sertoli cells are stimulated by ________, while leydig cells are stimulated by ________.
Lena [83]

Sertoli cells are stimulated by <u>FSH</u>, while leydig cells are stimulated by<u> LH.</u>

<h3>Sertoli and Leydig Cells:</h3>

The creation of T is stimulated by LH in Leydig cells, while the production of regulatory molecules and the nutrients required for maintaining spermatogenesis are stimulated by FSH in Sertoli cells in concert with T. As a result, Sertoli cells indirectly control spermatogenesis via T and FSH.

The growth and maintenance of the male reproductive system and spermatogenesis depend on LH-stimulated Leydig cell androgen synthesis. The interstitial cells of Leydig, which are concentrated heavily in the testis of newborn boys and adult males following puberty, release testosterone. Interstitial cells are another name for Leydig cells. The interstitial spaces outside of seminiferous tubules are where they can be found.
