The porine is the polyembryony animal, many obtains the ovocyte from the porine ovary although but the maturity quite to be low; Because the ROSI technology is does not have to grow the mature sole round sperm cell to pour into directly completely in the ovicell nature, jumped over the spermatozoon in to pass through the physiology and the biochemistry, if the ovicell nature mature or the activation degree were insufficient, added the round immature sperm cell maturity quite inferior reason, very possibly Causes the ROSI micro fertilization defeat.

猪是多胎动物，从猪卵巢上获得的卵母细胞数量虽然较多，但成熟度比较低；由于ROSI技术是将没有完全发育成熟的单一圆形精细胞直接注入卵胞质内，跳越了精子在穿过透明带和卵质膜等过程中所发生的生理和生化反应；如果卵胞质成熟或活化程度不够，加之圆形未成熟精细胞成熟度比较差等原因，很可能造成ROSI受精的卵母细胞内部激活因子蓄积减少和生成不足，引起精核解聚困难、精圆核不能形成、第二极体不能排出、卵母细胞孤雌发育率增加等，使ROSI显微受精失败。
