To Explore Whether The Difference in The Use Of Single-cavity And Double-cavity Egg Retrieval Needles Affects Egg Retrieval, Subsequent Embryo Culture And Postoperative Conditions

The results of the comparison and analysis of single-cavity and double-cavity egg retrieval needles are as follows. In terms of egg retrieval rate, although the single cavity egg retrieval needle group is lower than the double cavity egg retrieval needle group (83% vs 102%), in terms of the good embryo rate, single The cavity retrieval needle group was slightly higher than the double cavity retrieval needle group (67% vs 62%). Surprisingly, the average number of eggs retrieved in both groups was 12.4. According to the number of eggs retrieved, the overall statistical analysis results of the two groups are subdivided into three subgroups, namely the number of eggs retrieved is less than 10, the number of eggs retrieved is between 10-20, and the number of eggs retrieved is greater than 20. , We found that in the subgroup where the number of eggs retrieved is less than 10, single-cavity and double-cavity egg retrieval needles have a more significant difference in the egg retrieval rate (65% vs 91%). The use of double-cavity egg retrieval needles can The number of mature eggs obtained exceeds the expectation, showing that the double-cavity egg retrieval needle is more suitable for the situation where the number of follicles is small than the single cavity egg retrieval needle. However, the two groups have no statistical significance in terms of fertilization rate and good blastocyst rate. The difference. Although the double-cavity egg retrieval needle has the advantage of high egg retrieval rate, the rate of postoperative painkillers is significantly higher than that of the single cavity egg retrieval needle (30% vs 14%), indicating that the use of a single cavity egg retrieval needle for surgery can reduce Discomfort after the client's operation. Generally speaking, in the case of egg retrieval with a small number of follicles (less than 10 eggs), it is suitable to use the double-cavity egg retrieval needle with the advantage of high egg retrieval rate, and in the case of egg retrieval with a large number of follicles (the number of eggs retrieved) More than 10), it is suitable to use a single-cavity egg retrieval needle that can effectively reduce the probability of postoperative discomfort.
