Functional Morphology of Cryptorchid Leydig and Sertoli CellsThe development of the Leydig cells can be divided into three phases: (1) infantile, (2) prepubertal, and (3) pubertal phases (Figure 1). In each of these stages, Leydig cells have a typical appearance and their morphology is closely connected with the development of the hypothalamo-pituitary-gonadal axis.作者: OMIT 時(shí)間: 2025-3-30 00:21
