Three McGill University Doctors Link Abortions to Cerebral Palsy Risk

To get a yawn from a premature birth medical expert, tell him/her that any previous medical treatment that raises premature birth risk, also elevates the future risk of the newborn baby having the brain injury that is Cerebral Palsy (CP).

That is very established (over 50 years) news, and well known.

In 2013, three (3) McGill University doctors, led by Dr. Ghislain Hardy, linked induced abortions (IAs) to significantly raised CP risk.[1, Hardy];

How? By finding that women in Quebec (Canada) with prior IAs have 1.45 times the risk of very preterm deliveries (under 32.0 weeks gestation) and about double the risk of extremely preterm births as Quebec women with zero prior induced abortions.

Dr. Hardy et al., simply by finding significantly raised premature birth risk, CLEARLY IMPLIED future elevated risk of CEREBRAL PALSY was plausible.

IF a study finds that high stress increases the risk that young men will start smoking cigarettes, that by itself without any explicit statement by the research authors, has shown a plausible link between high stress for young men and raised lung cancer risk (via starting smoking).

Extremely premature (under 28 weeks gestation) newborn babies have 129 times the CP risk as do full-term newborn babies according to the 2008 ‘study of studies’ by Evelyn Himpens et al.[2, Himpens]

The 2013 ‘Hardy’ study is not the only paper to report XPB (extremely preterm birth) risk due to prior induced abortions.

The ‘Hardy’ study is the eleventh (11th) such study, with all 11 studies being listed at URL: [3, Rooney]

Opposed to these 11 statistically significant studies are a grand total of zero significant studies finding that prior IAs reduce extremely preterm birth risk.

Preterm babies come in 3 groups: extremely preterm (under 28 weeks gestation), very preterm (between 28 & 32.0 weeks gestation), & moderately preterm (between 32.0 & 36 6/7 weeks gestation).

For the full list of 147 significant studies finding Induced Abortions boost premature delivery risk or LBW (Low-Birth-Weight (under 2,500 grams) visit:


The 2014 El-Tallawy study reported that Egyptian women with prior abortions have 2.45 times the risk of delivering newborn babies with CP as Egyptian women with zero prior abortions.[4,Tallawy].

The ‘El-Tallawy’ included children of all gestation lengths (from extremely preterm to full-term to post-term [after 42 weeks gestation]).

Since induced abortions increase maternal INFECTION risk (a major CP risk factor), prior abortions boost future Cerebral Palsy risk for all such babies, regardless of how early or how late newborn babies are delivered.

How many estimated U.S. ACP (Abortion-CP) cases occur yearly?

The 2014 Egyptian study reported that prior IAs multiply future CP risk in newborns by 2.45.[4, Tallawy]

Using a more ‘conservative’ risk number (2.0) for the U.S. means that for the U.S., with about 15% of women delivering having an IA history, about 1,700 newborn U.S. babies yearly will be expected to have Cerebral Palsy due to women’s prior induced abortions.

According to Harvard University researchers Dr. Robert Fletcher and Dr. Suzanne Fletcher, the best medical evidence whether a purported risk factor is an actual risk factor is provided by a [competent] SRMA (Systematic Review & Meta-Analysis) type study.[6, Fletcher]

SRMAs combine data from many previous studies and compute risk numbers.

There have been three (3) SRMAs for the abortion-prematurity risk. [7, Ankum; 8, Shah; 9, Swingle]

The 3 SRMA studies all agree — they are unanimous — in finding that prior induced abortions significantly raise premature delivery risk.

Both the Ankum SRMA and the Swingle SRMA very importantly found that prior IAs multiply VERY preterm birth (under 32 weeks) risk by over 1.6 times (over 60% boost in VPB risk).[7, Ankum; 9, Swingle]

[Dr. Shah did not compute a VPB risk number].
