摘要
利用性控精液结合体外胚胎生产技术是获得预知性别后代的一种有潜在效率的方法。自20世纪90年代,利用流式细胞仪将X精子和Y精子分离开来,使畜牧生产性别选择的梦想变为现实,性控精液得到了极大的推广应用。本文重点阐述利用性控精液进行胚胎体外生产的研究和生产状况。
Use of sexed semen in conjunction with in vitro embryo production is a potentially efficient means of obtaining offspring of predetermined sex. The ability to sort individual sperm cells into viable X- and Y-chromosome-bearing fractions made producers＇ sex selection dreams reality in the 1990s and now semen can be sexed with greater than 90% accuracy with use of a flow cytometric cell sorter. However, there are some drawbacks to implementing the extensive use of sexed semen technology include the apparent lower fertility of sorted sperm, the lower survival of sorted sperm after cryopreservation and the reduced number of sperm that could be separated in a specified time period, The issues of In vitro production of bovine embryos using sexed semen and its application prospect are discussed in this review.
