Are designer babies worth it?
Thus, it is evident that Designer Babies are indeed very beneficial; they not only allow the baby's health to be improved, but also offer more opportunities for successful organ matches, treat those who are unfortunately genetically disordered, and allow parents to choose their favorable characteristics.
As a way of “designing” your baby, PGD is currently unattractive. “Egg harvesting is unpleasant and risky and doesn't give you that many eggs,” says Greely, and the success rate for implanted embryos is still typically about one in three.
Creating genetically-modified babies is both ethically justifiable and "highly desirable", according to an Abertay University bioethicist. Dr Kevin Smith claimed the risks of gene editing were now low enough to justify its use with human embryos.
Most Americans oppose altering genes of unborn babies to prevent serious inherited diseases and, especially, to enhance the baby's appearance or intelligence, according to a new poll conducted by Harvard T.H. Chan School of Public Health researchers and STAT.

Adam Nash is considered to be the first designer baby, born in 2000 using in vitro fertilizaton with pre-implantation genetic diagnosis, a technique used to choose desired characteristics.
It's been 20 years since the first designer baby was born to the Nash family from Denver, Colorado, but the news is still a miracle to many. Adam Nash was conceived for his stem cells from the umbilical cord, which was later used for the life-saving treatment for his sister suffering from Fanconi's Anemia.
Parents should not be able to choose from a menu of preferred traits for their children. This could hinder children from carrying unique genes and could thus eventually reduce genetic variation which is necessary for the human species to continue and live when environmental changes suddenly take place.
At 89 percent success rate, the study is the most successful attempt at CRISPRing human embryos so far. It may even be sufficiently high for IVF clinics, which can then screen the embryos and only transplant those with the corrected genes into mothers.
As alluded to earlier, the technology of creating designer babies is still not well-developed; hence, it may be practically unsafe for both the mother and the baby. According to some doctors, the technology could cause miscarriage or grave injuries to both mothers and children.
What is the science behind designer babies?
CRISPR designer babies are created by modifying DNA fragments to prevent and correct disease-causing genetic errors. CAS9 is a special technology which can remove or add certain types of genes from a DNA molecule, and most recently has been used after fertilization for gene-edited embryos.
The rise of designer babies would build new research platforms to study the areas that go beyond human health and wellness. ii. This technique may help reduce or eliminate the risk of life-threatening genetic ailments in unborn babies. iii.
Genetic engineering is likely to heighten parental expectations. If parents don't get the child of their choice – if the qualities they selected do not materialise or if the child fails to make use of them – their disappointment could lead to denigration or rejection.
Although this may seem quite harmless to most, the negative effects of designer babies are tremendous: the lack of diversity in our population, violation of a specific set of laws designed to protect humans, going against Christian views, and even destroying the roots of human nature.
This compelling documentary follows a couple who are trying to have a child with the right genetic make-up to save their son's life. It also talks to parents who have used PGD for gender selection and to leading scientists and ethicists from around the world.
However, germline editing, which Lulu and Nana received, involves editing heritable DNA found in sperm, eggs and embryos. Overt ethical concerns are raised by the possibility of permanent changes that edited people will carry and pass on to their children and their children's children.
Biohacking is easy to do. Anyone who wants to start modifying the genome in their garage can buy a DIY CRISPR kit for less than $200. There is a broad range of experimentation that can be done - from manipulating the genes of bacteria and yeast to self-experimentation.
Other methods by which a baby's genetic information can be altered involve directly editing the genome before birth, which is not routinely performed and only one instance of this is known to have occurred as of 2019, where Chinese twins Lulu and Nana were edited as embryos, causing widespread criticism.
The increase of lifespan within babies that could potentially have the procedure of genetic modification and engineering, done on them is thought to have up to 30 years. A potential 30 years just add to the human lifespan because of genetic editing as a baby still in the mother's tummy.
Designer babies are either created from an embryo selected by preimplantation genetic diagnosis (PGD) or genetically modified in order to influence the traits of the resulting children. The primary aim of creating designer babies is to avoid their having heritable diseases coded by mutations in DNA.
Can designer babies be smarter?
Embryos screened for intellect may gain only about 3.0 IQ points, on average. In reality, the benefits would likely be less substantial, and none could be guaranteed. In other words, a designer baby's IQ could "end up being much lower or much higher than what is expected," Carmi said.
It is important to understand that parents do not have to personally have the eye color they are seeking. They must only carry the genetic codes for that eye color that can be passed on to their child. Clearly, not every person who personally has green eyes has both or even one parent with green eyes.

Can a genetic modification/mutation make the body achieve immortality? That's a very interesting question! The short answer is no, probably not for humans. The most likely reason we get old and die is that living takes a lot out of us.
The two main procedures that can help prevent offspring of having a genetic defect is by IVF, In Vitro Fertilization, or PGD, Preimplantation Genetic Disorder.
A lab experiment aimed at fixing defective DNA in human embryos shows what can go wrong with this type of gene editing and why leading scientists say it's too unsafe to try. In more than half of the cases, the editing caused unintended changes, such as loss of an entire chromosome or big chunks of it.
These unwanted edits could alter other important genes - inadvertently triggering cancer, for example. But arguably, the most controversial aspect of gene-editing concerns the potential to introduce changes to the germline - DNA alterations that would pass down the generations.
