What male genital gland contains specialized cells that produce hormones and sperm?

The testicle is the male genital gland responsible for the production of hormones and sperm. Within the testicles, specifically in the seminiferous tubules, specialized cells called Sertoli cells support and nourish developing sperm cells, while Leydig cells (interstitial cells) produce the hormone testosterone. This hormone plays a crucial role in the development of male secondary sexual characteristics and reproductive function.

In contrast, the other glands mentioned play different roles in the male reproductive system: the prostate gland contributes to the mixture of fluids that form semen and helps with the ejaculatory process, the epididymis serves as a storage site for sperm and is involved in their maturation, and the seminal vesicle produces a fluid that nourishes sperm and makes up a significant portion of semen. While all of these components are vital for male reproductive health, the specific function of hormone and sperm production is intrinsic to the testicle.
