Overall, the analysis of some vaginal parameters revealed that the vaginal pH, the Nugent scores, the VEGF, TGF-β1, and TGF-β2 concentrations, and the lactobacilli counts in women RA and INF who became pregnant after the trial were similar or closer to those found in the vaginal samples obtained from the NPC group, composed by healthy fertile women (Table 4). Here, TGFB2 is linked to nasopharyngeal carcinoma.
