然而，部分患者在取卵日因为精神过度紧张出现取精困难，经心理疏导、药物治疗后多次手淫取精、夫妻性交中断法取精等处理后均失败，部分生殖中心有时通过电子射精仪取精，而大部分中心则需通过穿刺取附睾或睾丸精子来进行卵细胞胞质内单精子注射完成体外受精。

Ooplasmic transfer increases the fertilizability of the aged oocytes and the early embryonic viability, it has led to the birth of health babies, and become a hotspot in the realm of human assisted reproduction biotechnology and animal clone.

卵胞质转移技术能有效改善老龄卵母细胞的受精能力和早期胚胎的发育能力，在人类已有健康后代出生，它已成为人类辅助生殖生物技术和动物克隆研究的新热点。

Stage I of both male and female stone flounder appears only once in all its life, and the germ cells are comprised by spermatogonia or oogonia. The gonad from Mar to Aug keeps at stage II. The gonad index of testis at this stage is 0.037%, and the amount of spermatogonia is increased quickly. There is some linear germ plasm in the cytoplasm of spermatogina. In ovary at this stage it is mostly composed by oocyte of phase 2 which the character is the appearance of yolk nucleus, and no zona radiate in membrane. The mean GI of ovary is 1.95%. From Sep to Oct gonad is at stage III which testis is composed by lots of spermatogina and few spermatocytes, and the mean GI of testis at this stage is 0.086%. In ovary the ooctyes at phase 3 are in dominate position, the yolk nucleus disappear. And the GI of this stage is 3.35%. Both testis and ovary are at stage IV in Nov. hi testis the germ cells are in spermiogenesis, and the mean GI is 0.93%. hi ovary the oocytes are mostly at phase 4, which are filled in the cytoplasm with vitellin granule, and the zona radiate in membrane begins to formation. Nucleus moves to one side of the oocyte gradually. The mean GI of ovary at this stage is 9.37%.

在每年的3月-8月期间性腺处于Ⅱ期，此期精巢中精原细胞明显增多，胞质局部可见有线状的生殖质存在，平均成熟系数为0.037％；卵巢中以2时相卵母细胞为主，可见细胞质中出现强嗜碱性的卵黄核，细胞外由一层滤泡细胞包围，但尚无放射带，平均成熟系数为1.95％。9月-10月期间性腺处于Ⅲ期，此期精巢中仍有大量精原细胞，同时可见部分精母细胞，平均成熟系数为0.086％；卵巢中以3时石鲜孟加限加$玩印面n洲匆s性腺发生、分化及发育的周年变化相卵母细胞为主，细胞质中的卵黄核己消失，平均成熟系数为3.35%。11月性腺处于IV期，此期精巢内精细胞正处于不同的形成过程中，平均成熟系数为0.93%；卵巢中以4时相卵母细胞为主，胞质中充满染成桔红色的卵黄颗粒。
