It is such a blessing and a real MIRACLE to have a baby, so having two little MIRACLES is double the blessing.  We are very proud of our twin birth rate.  While there is no way to increase the odds of having twins other than implanting three embryos versus two, the fact is that 20-25 percent of the time, our pregnancies result in twins.  This is on par with any other fertility clinic in the world.  To increase this chance, intended parents can have two surrogates at the same time, using embryos that come from the same egg donor and biological father (the cost is approximately double for having two surrogates, but we do eliminate the egg donor charge for one surrogate program because you will be using the same egg donor).
