Maturation rates of cultured preantral follicles
| Groups | Number of follicles | Survived | Antrum formation | Ovulated follicles | Stages of oocyte development | ||
|---|---|---|---|---|---|---|---|
| GV oocytes | MI oocytes | MII oocytes | |||||
| Control (fresh follicles) | 300 | 256(85.50 ± 1.73) | 248(82.50 ± 1.73) | 234(78.25 ± 2.50) | 40(13.00 ± 1.83) | 56(18.75 ± 1.26 | 138(46.00 ± 1.41) |
| Toxicity follicles | 296 | 252(86.00 ± 2.16) | 229(81.50 ± 5.92) | 220(74.25 ± 2.99) | 37(13.75 ± 1.89) | 55(18.75 ± 3.10 | 128(43.50 ± 4.43) |
| Vitrified follicles | 310 | 239*(77.25 ± 1.71) | 202*(65.25 ± 2.63) | 200*(64.75 ± 1.71) | 58*(19.00 ± 0.82) | 50*(16.00 ± 0.82) | 92*(29.75 ± 1.50) |
In all cases, at least four experimental replicates were performed. Data are presented as n (% ± SD).
*; Indicates significant difference within the groups (P<0.05), GV; Germinal vesicle oocyte, MI; Metaphase I oocyte, and MII; Metaphase II oocyte.
