Following the Science on the Issue of Fetal Personhood

    

 This is in response to Wesley Smith’s National Review post, “Medical Journal Screed

Decries All Fetal Personhood Laws,” 18 October 2025.

When does a developing fetus becomes “human?”  Does human life begin at conception

or sometime later in the pregnancy? When, later in the pregnancy? What if you are wrong

about your dating by even a few days? Could you mistakenly be ending a human life because it

does not meet your assigned definitions? Does the developing fetus have legal rights as a

person or are they/is it not yet human? Is it not obvious that an ectopic pregnancy is a

miscarriage and that it becomes a triage situation and therefore, not an abortion?

The overall conversation is seen by many as a religious question, and it is, but a rational

and scientific case can be made for opposition to abortion without any resort to religious

arguments.  Many people will not listen to anything even remotely religious, but they might

 listen if the discussion can be framed in a scientific way.

            We have often been told to "follow the science." This is a good and valid idea. In order to

remain completely uniform in thought, this advice should be consistently applied. This article

will present, in a highly simplified way, the scientific information necessary for a case against

abortion and some forms of birth control.

This is a very simplified presentation of human conception and the passage of genetic

information from the parents to the offspring. The information may seem to be complicated and

overwhelming, but at least a simplified basic understanding is necessary for a scientific critique

of the practice of abortion. That is what I will attempt to provide for you here.  It is necessary to

start at the beginning.

DNA (deoxy-ribonucleic acid) is a molecule consisting of two strands of nucleotide

bases (adenine, guanine, cytosine, and thymine) paired together in two long strings arranged in

 the shape of a helix.  DNA, a very complex and, at the same time, a very elegantly simple

 molecule, is present in every cell of the human body and contains, in coded form, all the

information necessary to build and maintain the entire body.

Combinations of the four bases in pairs contain the entire human genome; the genetic

code which determines a person's sex, hair color, voice, skin color, height, body type, number of

fingers and toes, fat distribution, eye color, genetic diseases, intelligence level, possible allergies,

digestion, athletic ability, blood group typing, etcetera, etcetera, etcetera. The codes literally

determine everything about your physical body and genetic science clearly says that all the

information about you as a human individual is present from the moment of conception.

A very simplified explanation is this: each spermatozoan carries 23 chromosomes

containing copies of the father’s DNA and each egg cell contains 23 chromosomes containing

copies of the mother’s DNA. At fertilization, the two sets of chromosomes unite to produce the

zygote which has a total of 46 chromosomes (23 from the father and 23 from the

mother). There are, of course, abnormal situations when this process is distorted and birth

abnormalities result.

So, half of the individual’s genetic information comes from the mother and half from the

father. The chromosomal pattern in the fertilized egg is a hybrid of the coded instructions

present in each of the two source cells, made from them but individually different from each of

them; a fully separate genetic code, a totally distinct individual. To the mother’s immune

system, the fertilized egg is “Not Me,” it is a foreign body.   

The human female produces ova (eggs) which her body recognizes as "Me." Except in

rare cases of autoimmune disease, such as in immune oophoritis, the immune system leaves

the ovaries and the eggs alone. In autoimmune oophoritis, the body's immune system attacks

the ovaries as being “Not Me” and causes ovarian inflammation, severe damage, and fibrosis.

            Normally, when a sperm wins the frantic race to the egg, the egg immediately allows

the spermatozoan to enter and mix the DNA which it carries with the DNA which is present in

 the egg.  The resultant mixture of chromosomes is "Not Me," which presents a severe problem

because, if the body’s immune system is functioning properly it does not like "Not Me" and it

begins to makes moves to get rid of the "Not Me." It attacks "Not Me" to protect itself from

viruses, bacteria, and other organisms like yeast or protozoa. This is the reason why transplant

patients must take anti-rejection drugs for the rest of their lives. The transplanted tissues are

"Not Me" and would be killed if the body’s defenses are not properly suppressed.

To protect itself, the fertilized egg starts making proteins which tell the body, "move

on, there's nothing to see here." The proteins serve to hide the "Not Me." The body only sees

the "Me" and leaves the transplanted tissues alone.

Once the embryo implants and begins to increase in size, it rapidly becomes too "Not

Me" for the immune system to ignore, so the placenta takes over, releasing hormones, such as

progesterone, human chorionic gonadotropin, and other factors, to prevent rejection of the

fetus.

            The placenta is a temporary organ which contains both maternal and fetal tissue. Most

people recognize that the placenta nourishes the fetus, provides the fetus with oxygen, and

allows in some of the mother’s protective antibodies since the fetus’ immune system is not yet

functioning. It also allows the fetus’ waste products out into the mother’s blood system where

 they can then be properly eliminated. What people may not realize is that the placenta also

acts as a barrier and filter between the mother “Me” and the fetus “Not Me,” protecting the

“Not Me” from being killed. 

            Because of the placenta’s construction, the fetus and the mother effectively never come

into contact with one another.  Under the best of circumstances, the two bloodstreams never

mix. There are even two different types of hemoglobin at play, adult and fetal. The mother and

the fetus may also have different blood serotypes.

Remember that the fetus is "Not Me, " foreign tissue to the body of the mother. So,

what you have is, mother ("Me") and fetus ("Not Me"). Because the fetus has been effectively

disguised, the mother’s immune system, under normal situations, does not attempt to kill the

foreign material, the developing baby. 

This scientific information is one reason why there is so much controversy over when the

fetus becomes a separate, individual, and legally protected human, but this argument will not

convince everyone. The fertilized egg is clearly human tissue and is clearly genetically distinct

from tissue derived from the mother. None of this can answer the question of whether human

life legally begins at conception, at the first detectable heartbeat, or later.

Thirty-eight of the United States recognize the “unborn child” as a human and, in 2004,

United States President George W. Bush signed the Unborn Victims of Violence Act which views

unborn children as humans if they are injured or killed during the commission of specific federal

crimes such as terrorism. The United States courts have declared that these laws do not apply

to legal abortions.  My question is, “Why not?”  Is the only difference that the murdered child is

wanted and the aborted child is not?

Embryo Adoption

As a follow-up to my series of posts on Why Life Begins At Conception, here is something to think about from the edges of reproductive science: embryo adoption.

In-vitro fertilization is the procedure of fertilization of human eggs outside of the mother’s body and their subsequent implantation in the uterus..  This procedure is used when, for various reasons, it is highly unlikely, dangerous, or impossible for fertilization to occur in the natural way.   The procedure can be used for non-spousal donor fertilization, for fertilization after the death of the husband, or for implantation into surrogate mothers.  Some lesbians use this method to become pregnant.

It is common for 10 to 30 eggs to be chosen for fertilization.  The healthiest eggs are incubated for about 18 hours in a concentrated solution of sperm.  Any eggs which become fertilized are graded on several factors to choose those which will optimize the expected pregnancy rate.  With women under 30 the pregnancy rate approaches 50%.  The rate drops off sharply as the mother’s age approaches or exceeds 40.

Two to three of the optimal eggs will be implanted into the mother’s uterus.   The fate of the other fertilized embryos then becomes a controversial question.  Many agree with former US president George W. Bush that “These boys and girls are not spare parts.”

What currently happens:

1.     Many of the fertilized embryos are discarded or are donated to research laboratories.

2.     Some embryos are donated to other couples who are otherwise unable to conceive.

3.     Some of the embryos are intentionally implanted when conception is unlikely, letting “nature take its course.”

4.     Some couples pay to maintain their unused embryos in a frozen state. There are currently about 400,000 to 600,000 frozen embryos in the United States.

A growing movement among evangelicals is embryo adoption.  In 2003, there were about 11,500 embryo adoptions in the United States.  By 2010, the number had risen to about 15,000.

“The earliest Christians were distinguished by their care for those society discarded.  Embryo adoption seems to me a seminal way to do such a thinhg here in the third millennium.”  Gabriel Fluhrer. 

Why Life Begins at Conception, Part 4

The sperm (from the father) and the egg (from the mother) each carry one half of the parent’s genetic information.  At fertilization, a full set of genetic information is present; the exact same full set of information which is present in every cell of the adult individual.  Between thirty and one hundred fifty million sperm compete to reach an egg after each sexual act.  Each one of these sperm carries one half of the full set of the father’s genetic information.

The fertilized egg begins almost immediately to reproduce itself. Each copy carries a  full set of genetic information; the exact same full set of information which is present in every cell of the adult individual.

The cells form a flattened disk called the blastodisc and a groove, the neural groove, develops in the middle of the disk.  The walls of the groove rise up and close together to form the neural tube.  The neural tube becomes the spinal cord.  Each cell in the structure carries a  full set of genetic information; the exact same full set of information which is present in every cell of the adult individual.

This short video is of a chicken embryo, but the process is exactly the same in the human embryo.

At each step of the baby’s development every cell in the body carries a full set of genetic information; the exact same full set of information which is present in every cell of the adult individual.   If a blind DNA analysis were to be performed on two separately submitted specimens, on the embryo and on tissue taken from the mother, the result would be this: the analysis would show two individuals who were related genetically.  

Embryo Adoption

Many pro-life advocates are opposed to in-vitro (outside the body) fertilization and to embryo storage because "excess" embryos are often discarded or donated for stem cell research. For those of us who believe ** that human life begins at conception, this is nothing short of murder and it presents a special problem for those who, because of other medical conditions, can not get pregnant any other way.

There are currently about 500,000 embryos held in a frozen state. The majority will never be used for implantation. This leaves four possibilities for their future: 1. destroy them; 2. donate them for stem cell research, which results in number 1; 3. donate them to another family, or 4. keep them frozen, which will eventually lead back to number 1. The longest period of freezing known to have resulted in viable implantation is about ten years.

Christian couples who resort to this technique to become pregnant will have "excess" embryos over which they will have legal control. One option is making the frozen embryos available to other infertile couples; ie. embryo adoption, or FET (Frozen Embryo Transfer). This is an "adoption" because the baby is not the biological child of the second couple, but the second couple gets to experience a real pregnancy and a real birth. A failed implantation is not destroying the embryo, but is a failed attempt at pregnancy akin to a miscarriage.

Concerns are the cost (about $6000.00 per attempt), and the strong possibility of a multiple pregnancy.

One company providing this service in an explicitly Christian format is Nightlight Christian Adoptions, see www.EmbryoAdoption.org.

** (This is not just a religious faith statement. There is a solid scientific basis for the declaration that human life begins at conception. See my post on 29 July 2009. You can access the post at the "abortion" keyword at the end of this page.)

The abortion debate is not only based on religious beliefs

     A friend and I were talking  and somehow got onto the subject of abortion.  When I expressed my opposition to the practice he told me he was surprised at me.    He said, "You're so well read and seem to be intelligent.  How can you be anti-choice?"

     I pointed out to him that I am not anti-choice, I'm pro-life.  He started rolling out all the pro-abortion arguments.  And, he made the charge that only fundamentalist Christians and Roman Catholics oppose abortion; so, declaring that it was not necessary to invoke religion at all in the debate, I asked him a question.

     "If you take tissue from an aborted fetus and from the biological mother and submit the samples separately for DNA analysis and comparison, what will be the result?  ... The DNA analysis will demonstrate that the tissues came from two separate and totally distinct individuals.  Genetic science states that the fetus, from the moment of conception, is a separate life, not merely a patch of tissue in the mother's body."

     My friend admitted that this was true but the implications of that admission flew right over his head.  He resorted to the hypothetical game, "If your daughter were ... "

     Many people of both liberal and conservative orientations stake a claim on a particular issue on ideology and become almost automatons, chanting the established mantra over and over.  They challenge any deviation from their particular orthodoxy.  Real argument, in the classical sense, is drowned out; they merely become louder with their chanting.  If you don't agree with them you must be an uneducated boob, hopelessly confused, or, worst of all, a bigot.

     It would be a positive step if we could all learn to argue with respect.  At the end of our argument my friend and I looked at one another and laughed.  We're still friends.
