Human sex ratio is generally 1.06. The motility selected population of spermatozoa are usually Y chromosome rich. It is therefore easier to influence selected male births. Social and psychologic factors and economic needs intensified by high technology may cause further imbalance in the sex-ratio, creating a demand for techniques to influence sex selection. Such techniques may also help to handle sex linked defects. An examination of several studies on the sex chromosome distribution of human spermatozoa, based on HOP method, showed a preponderance of either X or Y bearing male pronuclei, depending on certain experimental conditions, indicating a technical possibility of influencing sex in an unbiased way.
人类性别比例一般为1.06。经筛选具有活力的精子群体通常富含Y染色体。因此，影响选择生育男孩相对更容易。社会心理因素以及高科技强化的经济需求可能会导致性别比例进一步失衡，从而产生对影响性别选择技术的需求。此类技术或许也有助于处理伴性缺陷。基于HOP方法对几项关于人类精子性染色体分布的研究进行考察后发现，根据特定实验条件，携带X或Y染色体的雄性原核占优势，这表明以无偏差方式影响性别在技术上是可行的。
