A (control), B (1 week-PHT), C (3 weeks-PHT), D (5 weeks-PHT), E (7 weeks-PHT), F (9 weeks-PHT) Normal Leydig cells (slender arrow); interstitial space with sperm cells (white arrow); seminiferous tubule (black span); vascular congestion (red arrow). Degenerated germ cells/Maturation Arrest (blue arrow). Thickened propria enveloping the tubules (green arrow), poor architecture (***).
