Which hormone acts on seminiferous tubules to enhance sperm production in males?

Follicle-stimulating hormone (FSH) is critical for male reproductive health, particularly in enhancing sperm production within the seminiferous tubules of the testes. It stimulates Sertoli cells that support and nourish developing sperm cells through spermatogenesis. This process is essential for producing a sufficient quantity of viable sperm, which can subsequently contribute to male fertility.

In males, FSH works in conjunction with testosterone, which is produced by Leydig cells and also plays an important role in the development of sperm, but it is FSH that directly acts on the seminiferous tubules to promote the production of sperm. This cooperative action ensures that spermatogenesis occurs efficiently and effectively.
