We learned a ton of good information on Tuesday, much of which I had never heard before so I wanted to share it with you all to clear up some of the myths around donor egg IVF:
Myth #1
Fifty percent of the genetic material is delivered by a sperm cell. Most men think their sperm is carrying their own characteristics. Actually their sperm is carrying genetic material from their entire gene pool (parents, grandparents, aunts, uncles, etc.). If the particular sperm that delivered the genetic material for your baby is carrying DNA for characteristics expressed in the father, the baby my resemble him. If, however, that particular sperm is carrying certain genetics from uncle Harry, for a little girl with curly blond hair and blue eyes, his daughter may look nothing like him with his straight dark hair and brown eyes. It is the luck of the draw. Each sperm cell carries an entirely different combination of genes from the man's ancestors.
The same is true for eggs. Any given egg contains genes from any group of ancestors and the eggs in B2 were formed using the exact same gene pool as my eggs would have been formed from. In fact using a sister as your donor means that your child will be your genetic and biological child.
Once the two sets of genes combine, another steps determines which traits will actually arise in the developing child. When the genes come together they all interact, some turn on, some turn off, so in reality, there is no telling which genes will do the instructing and who your child will act like, look like and sound like.
Myth #2
Although this is all called donor egg IVF, I will not receive B2's eggs. Once the genetic material from Mr. B and B2 has melded together in a laboratory the work of the sperm and egg is done. The combined material continues to duplicate itself until there is a ball of cells called an embryo and it is the embryo that is transferred to my uterus in hopes of implantation.
Myth #3
When a fetus grows inside of you, it takes the nutrients that your body already has, not what you are eating and drinking at the moment. In fact, most bodies run on a six month cycle, so the nutrients you took in 6 months ago is still in you supporting you in some way and this is what the fetus is using to grow. When you replace that nutrients, it enters the 6 month timeline of being used by the fetus. So if you are pregnant and eat garlic fries for lunch, it does not mean your growing child will also be having garlic fries for lunch.
So, in summary, B2's eggs are identical to the eggs I would have/should have had, a ball of cells will be transferred into me, not an egg and last but not least if I do get pregnant from IVF, what I am putting in my body now will be used up by the fetus to grow. Very interesting....
