Lisa and her husband Paul had six boys - three from a previous relationship of Paul's.
Desperate for a girl, the couple traveled to Thailand in July this year for a procedure no longer permitted in Australia.
Of Lisa's nine embryos, seven of them were boys, only two were girls.
They elected to have the two embryos implanted in Lisa in the hope at least one would survive.
Tragically, Lisa lost the two female embryos in the second or third week of the pregnancy after they had returned home from Thailand.
The entire family was devastated as a result.
Lisa defends her decision
Lisa knows many people will not agree with her decision.
Lisa says she loves her boys dearly and wouldn't change them for anything. But she says it's time they had a girl.
It is particularly hard for Lisa and Paul to have a girl and since the first attempt failed, she admits they are considering returning to Thailand to repeat the procedure.
IVF expert Dr Anne Clark won't pass judgement on what Lisa and Paul are doing but says the couple's reason for seeking sex selection - balancing the family - is not allowed in Australia.
Since a ruling by the National Health and Medical Council, the process has been outlawed in Australia since 2005.
Selection is still allowed when risky medical reasons prevail e.g. in some families, having a particular gender child may leave them predisposed to certain illnesses.
How a baby's sex is selected
In quite a simple procedure, doctors use a special stain which shows up x and y chromosomes when an embryo is 3 to 5 days old.

Kurt Fearnley: I was relief teaching in Blayney when I met Kurt as a young school boy. The first thing that struck me was his smile and contagious positive outlook at all times. I see nothing has changed with this outstanding Australian. Although I never saw him again, it is a testament to the power of his personality that I have not forgotten him more than 15 years later.

and not choose what sex they should be.
I also dont believe in having children just because
you want them. Remember, they are a blessing and
if you are lucky enough to have a child then you should be happy no matter what you are given.
miracles by fertility drugs and love them with all my heart but we
both want a girl I think we have the right to choose just as much as we have the right to choose to die
I don't believe in gender selection and truly urge Lisa to try being at peace with where she is and let what happens happen.
