Ultrasound – Is it Safe During Pregnancy?

Jill Black, a young woman, suspects she is pregnant and is filled with hope. One of the first things she may want to do is confirm the pregnancy. What better way to do it in the first 5-8 weeks than by having an ultrasound, with a picture of the little bean into the bargain.

Her medical doctors assure her that ultrasound is safe during pregnancy and that there are no adverse effects on her unborn baby. This view is contradicted by the Chinese Human Studies, which have been summarised by Jim West, a medical journalist. I have a copy of the The Chinese Human Studies. According to the Chinese Human Studies, this view (that ultrasound is safe during pregnancy) could not be further from the truth. Prenatal ultrasound harms DNA, cells and neurons of babies during pregnancy. These Chinese Human Studies have not been acknowledged by the medical fraternity in the Western world.

The Chinese Human Studies are real and legitimate. China has a one child per family legal policy. Abortion in China in early pregnancy is therefore acceptable, allowed, legal and ethical. This has made it possible to do randomised trials on women who will, at the end of the trial period, abort the babies. For the Chinese Human Studies, the growing embryos and fetuses (unborn babies) were exposed to varying frequencies and duration of ultrasound exposure, particularly in the first three months of pregnancy. After the babies were aborted, their tissues were examined and studied in the laboratory.

What they discovered is this:

Low intensities and brief exposures to diagnostic ultrasound in especially the early months of a pregnancy causes cellular, neurological and epigenetic damage to the unborn baby. Ultrasound causes harm to chorionic villi, to the chorionic tissue, to sensitive organs, the cornea of the eye, neurons, and DNA structures. The sheer volume of the Chinese Human Studies and the technical sophistication of their research methods provides strong evidence of cellular damage caused by ultrasonic waves. What they discovered is frightening.

You may be asking, “…but what about Western studies?” Well, critical studies have been done, mostly on animals, in the West. And, they have been largely ignored and repressed in favour of reassuring the public that diagnostic ultrasound equipment is safe for use in humans during pregnancy. The Federal and Drug Administration (FDA) approved the use of diagnostic ultrasound machines and raised the allowable intensity limit for diagnostic ultrasound machines in 1991. Women have flocked to the examination table motivated by the assurances of what an ultrasound can tell them about their babies’ health during pregnancy…for example does the baby have Downs Syndrome, is the baby a normal size and shape, is it a boy or a girl? Today 3D and 4D ultrasound pictures of our unborn babies have almost become an early measure of our success as mothers.

Diagnostic ultrasound during pregnancy is associated with chorioamnionitis (amniotic fluid infection), neonatal jaundice and childhood cancers (leukaemia, brain cancer). It affects the immune cells, which can lead to immune dysfunctions at birth and in childhood. Diagnostic ultrasound can make the baby vulnerable to vaccines that trigger autistic behaviour.

Professor Ruo Feng at the Insititute of Acoustics, Nanjing University, summarized recommendations for the use of diagnostic ultrasound in the year 2000. He said “We need to reiterate that in obstetric ultrasound, diagnostic techniques should carefully adhere to a cautious scientific attitude.

Specifically, abide by the following 5 points:

1. Ultrasound should only be used for specific medical indications.

2. Ultrasound, if used, should strictly adhere to the smallest dose principle, that is, the ultrasonic dose should be limited to using….the least intensity in as short a time as possible.

3. Commercial or educational fetal ultrasound should be strictly eliminated. Ultrasound for the identification of fetal sex and fetal entertainment imaging should be strictly eliminated.

4. For the best early pregnancy (the first three months), avoid ultrasound. If unavoidable, minimize exposure to ultrasound. Even later in the pregnancy, during the 2nd or 3rd trimesters, limit ultrasound exposure to 3-5 minutes for sensitive areas such as the fetal brain, eyes, spinal cord, and heart.

5. For every physician engaged in clinical ultrasound training, their training should include information on the biological effects of ultrasound and diagnostic ultrasound dose safety knowledge.”

In other words, a routine ultrasound at each visit to the obstetrician is not recommended! 3D and 4D scans for ‘nice pictures’ are not recommended. Neither are scans for determining the sex of your baby. I normally suggest a 13 week scan if you are worried about Downs Syndrome, and or possibly a 22 week anomaly scan. Unless there are medically indicated reasons for another scan, no further scans are necessary.

Learn to be aware of your baby’s movements and learn to listen to your body for signs of ill health, so that you can seek help when you need it. Ask your obstetrician/midwife to palpate your abdomen with his hands and to measure the growth(with a tape measure) and position of the baby.

Hands, eyes and ears are good diagnostic tools and an observant doctor or midwife can provide vital information in a normal healthy pregnant woman. Diagnostic ultrasound needs to be used only when medically indicated and with extreme caution, particularly in the first trimester of pregnancy.

  1. Great article, I was looking for this information during years of practice and betwen my two pregnancies. Thanks a lot, I would like to discover more and more about the damage of ultrasounf.

  2. You neglected to mention that Doppler to listen to the (echo of the) baby’s heartbeat, and external fetal monitoring also involve ultrasound and are actually higher intensity than the ultrasound used for scans.

    1. Thank you for mentioning this. Yes, a hand held fetal monitor is also an ultrasound doppler tool and it is possible to use a Pinard fetal stethoscope to listen to the baby’s heartbeat without risk to the baby. The fetal hand held doppler, though, is a lower intensity and dose than imaging ultrasound doppler and is predominantly used during labour when the risks to the baby are lower than in the early months of the pregnancy. I cardiotocograph which is strapped to the mother during labour is also an ultrasonic tool and if the baby has many exposures from conception until birth, it all adds up to levels beyond what is necessary for good health. A mother can ask her caregiver to use a Pinard during pregnancy and labour.

  3. I have been a midwife since 1978 and had a lot of information then that scans were not safe!! I am adding this article to my file of scan information! Thank you!!

    1. Hello Dixie!!I’m an independent midwife from Spain, I would be happy to have more information about the damage of ultrasound. Have you got any other resources?please, can you send them to my email? Thanks a lot. Regards from Spain.

    2. I remember back in 1985 that you talked about limiting ultrasound when you delivered Kyle and why. You even asked me after he was born if he’d been exposed to ultrasound for your records. So I know you’ve been watching this for a long time. It’s sad that doctors have been ignoring available information this long.

  4. Thank you, Marianne, for sharing what you learn as an independent and critical thinker. I had a bad feeling about all the recommended scans and now have the information I need to do what’s best.
