Figure 1. Effect of zearalenone (ZEA) on in vitro ovarian follicle culture. (A) The oocyte-granulosa cell complex (OGC) growth status (1 d, 4 d, 8 d and 12 d) in an in vitro culture model in both control group and 10 µM ZEA treatment group, in day 8 the follicle starts to form an antrum. The percentages of antrum follicle formation following treatment with 0, 3, 10 and 30 µM of ZEA are shown (B). * means P < 0.05, n = numbers of OGCs.
