So you have a pink nursery and are surrounded by dolls and dresses but you really want a boost of testosterone in your house, or maybe you want to break the rough and tumble life and stop having to buy band aids in bulk. OK, so maybe that was a little stereotyped, but you get my point – you want to mix up your kids a little and really don’t want to keep taking the risk that nature might not be on your side.
There have been so many old wives tales over the years about the best way to guarantee the gender of your baby – from diets, to sexual positions to who climaxes first but now we really can help you get the gender that you want to balance out your family if you wish.
The procedure is not easy, and neither is it cheap but for some patients it is definitely the right decision to make. We will be able to help you make that decision during your consultation with the medical staff here.
In order to do family balancing you will need to undergo an IVF cycle and then on day 3 when the embryos are at the 6-8 cell stage we will carry out PGD, where a single cell is removed from each embryo and then that cell is analyzed to see if it came from a male or a female embryo. It is then possible for us to relate that information back to each embryo and thus select the required gender for transfer.
The gender of any particular embryo is determined by the sperm – all normal eggs will contain a single copy of an X chromosome and then a normal sperm will contain either a Y chromosome or an X chromosome. To make a female embryo then the sperm that fertilizes the eggs needs to contain an X chromosome and to make it male it will have a Y chromosome.
Statistically speaking when sperm are created the distribution of X and Y chromosomes is evenly spread and so there should also be an even distribution of male and female embryos created as well. That being said, during an IVF cycle we cannot guarantee that this will be reflected in what we see. A good example of this is the fact that when you toss a coin you will eventually get heads 50% of the time and tails 50% of the time, but it is quite probable to get 10 heads in a row on the way to getting that equal distribution.
There are a lot of hurdles during an IVF cycle for anyone, but when we are doing PGD for family balancing purposes they can be magnified in some cases. In a regular cycle there is always a drop off from the number of follicles recruited to the number of eggs retrieved, fertilized and then making good quality embryos. As far as PGD is concerned there is also the fact that the embryos have to have reached at least the 6 cell stage to be really appropriate for biopsy and then develop all the way to a blastocyst ready for transfer on day 5.
There is also the fact that there is a chance that the embryos that look most appropriate to be transferred are not of the desired gender at all or even that the only embryos that we obtain may be of the opposite gender to that which you are looking for. In these cases you will have to make a decision as to what to do and that decision will have to be made within a matter of hours due to the timing of the transfer.
That all being said we have had many successful cases where the desired gender is obtained and the couple achieves a pregnancy. For more details please make an appointment for a new patient consultation and also check out the other information on the web site regarding IVF and PGD treatments.
