Our expert says:
The use of sperm separation techniques for gender selection is highly unreliable and should be avoided. A much more accurate means of gender selection would be to go through the in-vitro fertilization route combined with embryo testing by means of a process called pre-genetic diagnosis. The costs are formidable and may approximate to as much as R40000 to even R50000 depending on the number of embryos that require testing. By the method of pre-genetic diagnosis, should a pregnancy be obtained, the successful results are as high as 95%. The process involves ovulation induction and harvesting of the eggs as well as fertilization of these eggs in the laboratory setting to produce embryos. Once embryos have been obtained these embryos are individually tested for not only for the gender but also for chromosomal abnormalities and only the healthy required embryos are utilized for embryo transfer back into the uterus. The chance of conceiving through this method is the same as that for other on-vitro fertilization procedures and is in the region of 40%. However should a pregnancy be established then the likelihood of the correct gender is as mentioned previously, extremely high.
