Within mammalian ontogenesis, the reproductive system reaches full maturation and adult function later than any other organ system. This is particularly true of the gonads and their key role in reproduction. Although significant propagation of germ cells occurs in the immature male gonad, and the population of fetal-type interstitial cells (Leydig cells) exercises an essential influence on the development of the endocrine and phenotype sex, testicular maturation, leading up to male fertility, is not completed until puberty. It includes the successive establishment of the process of spermatogenesis within the emerging seminiferous epithelium of the testicular tubules and, at the same time, the final maturation of Leydig cells. This period is the subject of the present study.
