We did over 47,000 gender determinations in the past 10 1/2 years with five errors. That is a 99.95%!  Two errors were not quite 15 weeks when the sessions were done - a little early to do it but did so at request of clients, the third was a hiding twin that we corrected on second visit! Fourth was undescended testicles that even her doctor got it wrong! Fifth was undescended testicles again!

We know that finding out the sex of your baby is very important. If we can not determine the gender of your baby for any reason, you may return again within two weeks for no additional charge.
