Histological study of neonatal testis

Abstract

During prepubertal development in most species, normal testicular growth is associated with dramatic proliferation of Leydig cells in the interstitium and an increased number of Sertoli and germ cells within the seminiferous epithelium. The study was designed to study the histology of neonatal testis. Ten specimens of human neonatal testes their age range from 10 -45 days were prepared, fixed, sectioned and stained. In early postnatal life the human seminiferous tubules is composed of solid cords containing two cells, the precursors of sertoli cells and the cells of the germinal course.
