The transport of eggs from the site of ovulation to the site of implantation is a fundamental step of the reproductive process in the female. The fallopian tube effects the major part of this function and times the passage of eggs into the endometrial environment. As a result of different combinations of speed of progression and retention periods through the various regions of the oviduct, the pattern of transport differs from one species to another. The role of muscular contraction, ciliary movement and flow of secretions in the mechanisms of progression and retention are still poorly understood. Estrogens and progestins have a pronounced influence upon egg transport, but the responses to exogenous hormones are quite variable and depend mainly upon species, dose and time of administration. Species differences prevent from broader generalizations at this time and indicate the need for further comparative studies.
卵子从排卵部位运输到着床部位是女性生殖过程中的一个基本步骤。输卵管在这一功能中起主要作用，并控制卵子进入子宫内膜环境的时间。由于通过输卵管各个区域的推进速度和停留时间的不同组合，不同物种的运输模式也有所不同。肌肉收缩、纤毛运动和分泌物流动在推进和停留机制中的作用仍知之甚少。雌激素和孕激素对卵子运输有显著影响，但对外源激素的反应差异很大，主要取决于物种、剂量和给药时间。目前，物种差异阻碍了更广泛的概括，并表明需要进一步的比较研究。
