Organs combining endocrine and non-endocrine functions — The endocrine part of the testis

The Testis (testicle) is a male gonad responsible for sperm maturation and The production of Male Sex Hormones (testosterone). These sex hormones mature within the testicular endocrinocytes (Leydig Cells), which are located in the lobules between the convoluted seminiferous tubules. Testicular Hormones determine The Development of secondary male sex characteristics (Hair growth, laryngeal development), promote The formation of synostoses in the Skeletal System, accelerate Muscle Development, induce penile erection, and stimulate sexual desire and human psyche.

Sex hormones stimulate METABOLISM, particularly Lipid Metabolism, enhance the secretory and hormonal function of the Prostate Gland, and also influence the function of the reticular zone of the adrenal cortex and The Thyroid Gland.
