Here is the bit he refers to when he says;
This action of the pill will be discussed again in this booklet.
Q. I have heard some people say the pill has an abortifacient capacity. What does this word mean, and is it really true anyway? A. Before answering this question it is very important that we all have a correct understanding of the key biological terms related to pregnancy. The following definitions have been accept by major medical texts for decades.
'Conception' refers to the moment at which the sperm penetrates and fertilises the ovum to form a viable zygote. It does not refer to the process of implantation of the newly created human embryo, which is a separate event, occurring about 7-8 day’s after conception. A woman is pregnant because conception has occurred, not because implantation has occurred. This distinction is important.
At the precise and unique moment of conception, a woman is 'pregnant' with "a new individual ". This is an accurate and informed medical description. It is the same terminology used by Prof. John Dwyer, pre-eminent Australian AIDS expert and researcher, who has described the moment that the sperm enters the ovum as the creation of a "new and unique individual". Well known medical writer, Professor Derek Llewellyn-Jones, author of Everywoman, has also written that when the male genetic material from the sperm joins with the female genetic material in the ovum, " a new individual is formed".
To stop conception occurring, that is, to stop sperm and ovum joining, is contraception. Condoms, diaphragms, spermicides, vasectomy and tubal ligation are accurately described as methods of contraception. Obviously any drug or device used after conception has occurred cannot be termed a contraceptive.
The correct term to describe any interference with the pregnancy after conception has occurred is ‘abortifacient’. This is the precise biological description for any drug or device that acts to end a pregnancy once it has begun at conception.
You might be interested to know that many major medical dictionaries have definitions of ‘conception’, ‘pregnancy’ and ‘contraception’ that are the same as those listed above.
It is medically dishonest to break from these definitions. And yet, this is precisely what some scientists have recently started to do. They seek to define pregnancy as beginning with implantation, not fertilization. But as I mentioned ealier, implantation occurs 7-8 days after the new human person has come into existence. The pregnancy, and the new human person, are already many days old by the time implantation has occurred.
Therefore, what these scientists are trying to doing is get people to think that abortifacient drugs such as the pill are really just contraceptive drugs. Do you see the clever shift in definitions these scientists are trying to make? Redefine when a pregnancy and new human life begins, and you redefine the key characteristic of the drug – how it works!
Obviously many people object to abortifacient drugs because they can cause a loss of human life. Not so many people object to methods of contraception (condoms, diaphrams etc), because these methods prevent new human life being created. Hence, if scientists succeed in convincing people that human life begins after implantation, eventually most people will have no objection to the pill. They will have been tricked into believing that human life had not begun when the pill exerted its anti-implantation effect.
Q. So how do you prove that the pill acts as an abortifacient? A. The answer to this question can be found by comparing the rate of break-through ovulation and the detected pregnancy rate. The ovulation rate has been reported to be about 27 ovulations in 100 women using the pill for one year. But the detected pregnancy rate is much lower at around 4 pregnancies per 100 women using the pill for one year.
As you can see, there is a big difference between the number of women who ovulation (27) and the number of detected pregnancies (4). What has happened within the woman’s body to reduce the high ovulation rate to such a low number of detected pregnancies? I suggest that one answer to this important question is that pregnancies have begun, because ovulation and fertilization have occurred, but some of these pregnancies are terminated because implantation cannot take place. The pill has damaged the lining of the womb, stopping implanation.
Q. You talk about the pill causing damage to the lining of the womb, but what does this really mean? A. The process of implantation of the human embryo into the lining of the womb is a very complex and delicate process. Proper attachment and successful implantation is under the guidance and control of a vast array of ‘implantation factors’. These chemical factors, with names such as interleukins, PAF and LIF, actually cause what is referred to in medical journals as "cross-talk" between the embryo and the cells which line the womb. That is, the cells of the new human embryo and the cells of the lining of the womb chemically speak to each other. The purpose of this chemical communication is so the womb will be fully prepared and ready to bind with the human embryo when it attempts to implant.
The pill’s role in all of this is that it alters the levels of these implantation factors. Too much estrogen and progesterone, via the pill, causes harmful changes to the levels of these implantation factors. Recent research has shown that implantation fails if the levels of estrogen and progesterone are too high.
It is because the levels of these two hormones are wrong that the week-old embryo cannot attach to the womb. Cell talk fails, the proper development of the womb doesn’t occur, and the embryo dies from a lack of nutrition normally supplied to it from the lining of the womb. In fact, wrong levels of artifical progesterone have been shown to cause a very thin lining of the womb, making implantation impossible.
You can understand this concept more fully by considering the example of a space shuttle, low on fuel and oxygen, which urgently needs to dock with the space station. The mother ship and the shuttle communicate with each other so that the shuttle knows which docking bay to go to. Importantly, the mother ship knows which bay to make ready. If this electronic communication fails – disrupted "cell-talk" --, the shuttle may go to the wrong docking bay, fail to attach to the mother ship, drift away, and the crew dies from a lack of food and oxygen. Or it might go to the right bay but not find all the docking apparatus in place. Again, the attachment between the two fails due to faulty communication and the crew dies.
As well, there are a special group of molecules found both on the lining of the womb and on the 7-8 day old human embryo known as integrins. Integrins are referred to as ‘adhesion molecules’. Researchers have shown that these adhesion molecules greatly assist the process of implantation. Going back to our example of the docking process between a space shuttle and the mother ship, integrins could be thought of as grappling hooks that ‘hold’ the human embryo onto the womb whilst the process of implantation is completed. The artifical hormones in the pill have been shown to damage the ability of integrins – the implantation ‘hooks’— to function properly. Because of this damage to the proper functioning of integrins, the limited amount of time the human embryonic person has for attached, known as the ‘window of implantation’, is closed. As a result, the human embryonic person dies.
As you can see, the pill acts as the great communication wrecker.
