Control group and DEHP experimental group offspring (F1-F4) male rat’s epididymis histology expression.

Normal control group of testicular seminiferous tubule epithelial developed normally, we can observe each stage sperm cells and a large number of sperm cells in the epididymis pipe. DEHP experimental F1 generation observed seminiferous tubule epithelial obvious atrophy, less sperm cells, pathologic hyperplasia of interstitial cells, number of sperm in the epididymis lumen scarce or lack, luminal epithelium cell falls off. F2 generation of rat testis partial seminiferous tubule epithelium atrophy, sperm cells less; F3 and F4 generation were tend to be normal, sperm cells grading well. A:F1;B:F2;C:F3;D:F4 E: Control (200×).
