Sperm-sorting fails to seperate boys from girls

Sex-selective abortion is the practice of terminating a pregnancy based upon the predicted sex of the infant. The selective abortion of female fetuses is most common where male children are valued over female children, especially in parts of East Asia and South Asia particularly in countries such as People's Republic of China , India and Pakistan , as well as in the Caucasus , Western Balkans , and to a lesser extent North America. Sex selective abortion was first documented in , [4] and became commonplace by the late s in South Korea and China and around the same time or slightly later in India. Sex-selective abortion affects the human sex ratio —the relative number of males to females in a given age group, [5] [6] with China and India, the two most populous countries of the world, having unbalanced gender ratios.

Sperm sorting is a means of choosing what type of sperm cell is to fertilize the egg cell. Several conventional techniques of centrifugation or swim-up. Newly applied methods such as flow cytometry expand the possibilities of sperm sorting and new techniques of sperm sorting are being developed. It can be used to sort out sperm that are most healthy, as well as for determination of more specific traits, such as sex selection in which spermatozoa are separated into X- female and Y- male chromosome bearing populations based on their difference in DNA content. The resultant 'sex-sorted' spermatozoa are then able to be used in conjunction with other assisted reproductive technologies such as artificial insemination or in-vitro fertilization IVF to produce offspring of the desired sex - in farming animals but also in human medical practice.
