AMH and endometriosis: A small decrease in percentage of cells in S and G2/M phases was observed (Figure 4A) with a concomitant increase of cells in pre-G1 phase (Figure 4 B).Various semi-quantitative RT-PCR have been used to quantify the expression levels of AMH and AMH RII isoforms in both endometriosis epithelial and stromal cells (Figure 5A).
