These results suggest that cftr in sperm may be involved in the transport of hco3 - important for sperm capacitation and that cftr mutations with impaired cftr function may lead to reduced sperm fertilizing capacity and male infertility other than cbavd 研究结果显示，精子的cftr功能为碳酸氢根的传输，促使精子获能；而cftr基因突变引致功能失效，会降低精子授精能力，这是先天性无输精管以外另一导致男性不育的可能因素。
In this study , by combining rt - pcr and race , a full - length cdna encoding the lagurus lagurus zp3 ( lzp3 ) was isolated from the lagurus ' s ovary and cloned into a prokaryotic expression vector and a eukaryotic expression vector for further immunocontraceptive investigations 本论文研究工作采用rt - pcr与race相结合的方法，首次克隆了草原兔尾鼠zp3全长cdna并进行了序列分析，构建了真核表达质粒，为草原兔尾鼠免疫不育的研究奠定了基础。
Conclusion the results of present study indicated that chromosome abnormality is one of the frequent genetic causes for male infertility , suggesting that it is essential to screen chromosome abnormality during diagnosis of male infertility as well as before in vitro assisted fertilization by intracytoplamic injection 结论染色体异常是男性不育的一个常见遗传病因，在男性不育的诊断和卵细胞浆内单精子注射受精治疗前，对染色体的异常进行筛查十分必要。
She felt the force of the bacchae in her limbs and her body , the woman gleaming and rapid , beating down the male ; but while she felt this , her heart was heavy . she did not want it , it was known and barren , birthless ; the adoration was her treasure . it was so fathomless , so soft , so deep and so unknown 但是，当她觉着这个的时候，她的心是沉重的，她不要这一切，这一切都是不神秘的，光赤的，不育的，只有崇拜的温情才是她的宝藏，这写藏是这样的深奥而温柔，这样的神秘而不可思仪！
The paraffin section analysis showed that there were no difference between transgenic sterile plants and control fertile plants in the development and structure of pollen sac . in order to analyze the sterility mechanism further , we handled the pollen mitochondria in normal temperature and heat shock response , then we extracted the mitochondrion proteins and make variance analysis 石蜡切片分析表明，转基因不育植株的花粉囊的发育和结构与对照的可育植株之间没有任何差异，只是花粉囊中的花粉在不育株中是不育的，而可育株是可育的。
