Arsenic + hCG	2.10 ± 0.05	1.48 ± 0.16	15.16 ± 1.82*	18.62 ± 0.64*	46.84 ± 3.24*	8940 ± 246*

Each value represents mean ± SE, n = 12. (ANOVA followed by multiple comparison two-tail t-tests, * p < 0.01, ** p < 0.001 as compared with respective control). Asg = spermatogonia-A, pLSc = preleptotine spermatocytes, mPSc = midpachytene spermatoeytes, 7Sd = stage 7 spermatids.
