To make the wapiti sperm capacitated in vitro, we selected and used the method of sperm-up. By making the rate of acrosome reaction as a main index, and the sperm energy, the survial time and the fertilizated rate of wapiti sperm and hamster mature oocytes as auxiliary indexes, it were carried out to compare the effects of wapiti sperm capacitation in vitro under different temperature, different density of pyruvate sodium, caffeine and heparin and different culture medium.

对马鹿精子，使用上浮法诱导其获能，通过对顶体染色测定精子的顶体反应率并作为主要指标，同时以精子活力、精子存活时间和异种受精率为辅助指标，对精子的获能效果进行评价，以比较不同培养温度、丙酮酸钠浓度、咖啡因浓度、肝素浓度以及培养基对马鹿精子体外获能效果的影响。

The research work can make us acquire the further recognition of molecular mechanism about blastocyte implantation and parturition and provide the theoretical basis for some leading-edge problems, such as organ transplantation, homeoclone or heteroclone. In the meantime, the result might be used as possible targets of medicine development for the cure of some reproductive diseases, such as sterility, abortion and fetal malformation.

研究这些关键过程将使我们对胚泡植入和分娩的分子机理获得进一步的认识，同时也可为器官移植、同种或异种克隆等研究热点提供基础理论依据，在临床上也为治疗一些妊娠疾病如不孕、流产、胎儿畸形等提供药物可能作用的靶位点。
