Whilst on a recent google look around I found this - I thought of this thread and thought it may be worth posting it for anyone who wanted to use this service, it is in the US though.


..... uses a technique, which was developed in the early 1980’s. The technique is based on the fact that sperm carrying the Y chromosome move somewhat faster than sperm carrying the X chromosome. A laboratory process is used in which sperm must swim through a sticky protein liquid (albumin), the assumption being that in a given period of time, more Y-bearing than X-bearing sperm will speed through the albumin. By repeating this process, a sperm concentrate is finally obtained which contains a relatively high percentage of Y-bearing or X-bearing sperm (depending on which procedure is selected) than the original sperm sample. The resulting concentrate can then be used by a physician or qualified nurse to perform an intrauterine insemination (IUI).

Clinical data suggests that the sex selection method produced a success rate of 78-85%for male sex selection, and 73-75% for female.
