作者用口径仅１ｍｍ的透明塑料管进行了ＨＦＭＣ抗生育体外模拟注射实验，结果表明先注射ＨＦＭＣ再注射沉淀剂便于ＨＦＭＣ附着于管壁井与沉淀剂混合沉淀。对８只日本大耳白兔行输精管顺行及逆行注射以染料着色的ＨＦＭＣ在输精管内的分布，结果显示顺行注射ＨＦＭＣ量超过输精管的自然容积，易于从输精管一膀胱口排出。日本大耳白兔１４只用于比较顺行及逆行两种不同注射方向及逆行注射不同剂量ＨＦＭＣ后精子密度及生育力指数以了解输精管的通畅情况及避孕效果，结果表明顺行注射ＨＦＭＣ难以达到避孕目的，而逆行注射一定量的ＨＦＭＣ以保证ＨＦＭＣ在输精管内形成足够沉淀，则可达到避孕的目的。因此，在将来的实际应用时应先逆行注射２０％ＨＦＭＣ，然后再注射少量沉淀剂，剂量应为从注射点到附睾端输精管自然容积的三倍。
The authors used HFMC to simulate the in vitro fertilization experiment with a transparent plastic tube with a diameter of only 1mm. The results showed that the injection of HFMC followed by injection of the precipitating agent facilitated the HFMC to adhere to the mixed wall of the tube wall and the precipitant. The distribution of dye-stained HFMC in the vas deferens in 8 Japanese white rabbits was determined by cisplatin and retrograde injection. The results showed that the amount of HFMC injected in parallel was higher than the natural volume of the vas deferens and was easily excreted from the vas deferens. Japanese white rabbits 14 were used to compare two different directions of retrograde and retrograde injection and sperm density and fertility index after retrograde injection of different doses of HFMC in order to understand the patency of the vas deferens and the contraceptive effect.The results show that cisplatin injection of HFMC is difficult to achieve The purpose of contraception, and retrograde injection of a certain amount of HFMC to ensure adequate deposition of HFMC in the vas deferens, you can achieve the purpose of contraception. Therefore, in future practical applications, retrograde injection of 20% HFMC should be followed by a small injection of precipitant at a dose that is three times the natural volume of the vas deferens from the injection site to the epididymis.
