These experiments were carried out to investigate fertilizable and developmental ability after zona drilling the unfertilized eggs and the eggs not fertilized by the 1st insemination. The results of in vitro fertilization of the mouse eggs treated by using micromanipulation and acid tyrode's solution with capacitated epididymal spermatozoa were as follows. In the case of ovulated unfertilized eggs, according to sperm count(106, 105, 104 and 103/ml) the rates of in vitro fertlilization treated by zona drilling were 86.0%, 82.0%, 70.0% and 54.0%, respectively, and those of control were 58.0%, 52.0%, 12.0% and 8.0%, respectively. The rates of in vitro fertilization of zona drilled eggs were significantly high compared with those of control, and there were no significant difference between two groups. According to the sperm count the zona drilled eggs developed to the blastocysts were 51.4%, 40.5%, 23.3% and 17.4% and those of control were 35.7%, 26.3%, 0% and 0%, respectively. Also, in the eggs not fertilized by 1st insemination, the fertilization rates of oocytes reinseminated after zona drilling was significantly higher(83.5%) than that of control(34.7%), and the rates of polyspermy were similar. The rates of development to the blastocysts was 18.6% in the zona drilling treated eggs, and that of control was 27.3%, there was no significant difference between two groups. These results indicated that oocytes not fertilized by 1st insemination as well as ovulated unfertilized eggs could be fertilized, improve fertilizing rates by zona drilling treatment, and development potential were normal.
