Recently, it was National Coming Out day, a day for raising awareness for the acceptance of LGBT people by our community. Today, my family and I were talking about what it could feel like to have a gay child.
My mom said it would be weird… you could not go visit that child and his/her spouse and their kids… because any kids they had would not be 100% their own! The most a gay couple can do is use one parents’ DNA and combine in with a donor’s. But really, with medical technology progressing the way it is, will this be true for much longer?
There are constantly being tests being done by scientist to learn more about how we can control life, whether with cloning, stem cells, or growing new organs for patients who need a transplant. It could definitely possible to have a same-sex couple have their own genetic children. It would be difficult and expensive, and it would require egg extraction, but it could be done. Perhaps not now, but I would bet within 20 years.
The ovum, or “egg”, from a female human is about 20 times the size of a human sperm. This is because the sperm is essentially just a swimming nucleus of DNA. The ovum, however, has cytoplasm, mitochondria, and all that other cell stuff. These other components of the cell are what are able to replicate to create every functioning cell in the human body.
Of course, the main difference between an ovum and any other human cell is that an ovum only has half of a full set of chromosomes; it needs to be met with a sperm which has the other half in order to form a full set of human DNA and begin to replicate. The nuclei of the ovum and of the sperm, I believe, are essentially the same. It is the rest of the cell that makes the difference.
So, what do you need to make a new baby? You need an ovum and half a nucleus from each parent.
Theoretically, for a gay male couple to have a biological child, you could take an egg from a donor, extract the nucleus from the ovum, and insert the nuclei from the two fathers. As long as at least one of the two nuclei contained an X chromosome, the egg could then be implanted into a surrogate mother, and grow into a baby!
For two women, you would take an egg from each, and transplant the nucleus from into the other. Then the two nuclei would combine inside the one ovum. Of course, by this method, a lesbian couple could only give birth to a daughter, since the mothers’ nuclei would only be X chromosomes sets.
How far fetched is this? I think some procedure like this may have successfully been done already. If I made a habit of reading up on scientific journals, perhaps I would know. I know that this procedure IS expensive and difficult and does not have a high success rate. However, as technology improves, it will definitely get easier!
