The development of the seminiferous tubule in the first year of life was studied with the electron microscope in five biopsies of normal testes. When HCG stimulation ceases, the fetal Sertoli cell changes into the Sa-Sertoli cell. The possibility of the fetal Sertoli cell having a hormone producing role is discussed. Gonocytes can be detected until the third month post natum. In addition to the gonocytes fetal, transitional, Ap and Ad spermatogonia are also present in the first year of life.
运用电子显微镜对五例正常睾丸活检组织进行研究，观察出生后第一年生精小管的发育情况。当人绒毛膜促性腺激素（HCG）刺激停止时，胎儿型支持细胞转变为Sa型支持细胞。文中讨论了胎儿型支持细胞具有产生激素作用的可能性。直到出生后第三个月仍可检测到生殖母细胞。除生殖母细胞外，胎儿期、过渡型、Ap型和Ad型精原细胞在出生后第一年也存在。
