because monoamine releasers are well known to be strongly teratogenic, and it would be utterly bizarre if MDMA were an exception.

Are you sure about this? My wife has been on a prescription for Adderall for a while, and when she became pregnant she, of course, stopped taking it. But then, when she started struggling to maintain her level of performance at her job, she started checking into the studies and speaking with midwives and an obstetrician. Generally, they would always first give her the safe, err-on-the-side-of-caution, cover-my-ass response, advising her against taking it. But when pressed for a source, and in our own searches for journal articles, we found that there are no studies conclusively demonstrating either safety or hazard for amphetamine.
Amphetamine is classified as a category C drug in pregnancy, which is defined as: "Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks."
Already, the classification system acknowledges that there may be cases in which the potential benefits outweigh the potential risks (a la the far-fetched example I gave for the MDMA and PTSD).
Additionally, I found the details on those animal studies and found them to be rather stretched to begin with. There were 2 studies, one with rats and rabbits, and another one with mice, both of which were given doses vastly exceeding the comparative maximum doses for humans. The rat and rabbit study found no effect on the development of the fetuses. The mouse study did observe fetal malformations and death. However, the drugs were administered a dose comparable to 6 times my wife's daily dosage, and the dose was administered by injection. The study also mentioned that this dose and route was also associated with severe maternal toxicity.
I think it goes without saying that if the dosage (of ANYTHING) is high enough to be severely toxic to the mother, the fetus will suffer as a result. Even if the drug itself never crosses the placenta and directly affects the fetus, the damage to the mother will indirectly affect the fetus.
I really don't feel like either one of these studies effectively demonstrates a teratogenic effect from this drug. Here are the summarized details of those 2 studies.
Amphetamine, in the enantiomer ratio present in Adderall® (d- to l- ratio of 3:1), had no apparent effects on embryofetal morphological development or survival when orally administered to pregnant rats and rabbits throughout the period of organogenesis at doses of up to 6 and 16 mg/kg/day, respectively. These doses are approximately 1.5 and 8 times, respectively, the maximum recommended human dose of 30 mg/day [child] on a mg/m2 body surface area basis. Fetal malformations and death have been reported in mice following parenteral administration of d-amphetamine doses of 50 mg/kg/day (approximately 6 times that of a human dose of 30 mg/day [child] on a mg/m2 basis) or greater to pregnant animals. Administration of these doses was also associated with severe maternal toxicity.
A number of studies in rodents indicate that prenatal or early postnatal exposure to amphetamine (d- or d,l-), at doses similar to those used clinically, can result in long-term neurochemical and behavioral alterations. Reported behavioral effects include learning and memory deficits, altered locomotor activity, and changes in sexual function.
Finally - as far as we were ever able to find, there has been only ONE documented case of a woman using amphetamines and subsequently giving birth to a malformed baby.
There has been one report of severe congenital bony deformity, tracheo-esophageal fistula, and anal atresia (vater association) in a baby born to a woman who took dextroamphetamine sulfate with lovastatin during the first trimester of pregnancy. Amphetamines should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
As shown here, the woman was also taking Lovastatin, which is a category X drug for pregnancy, which are for drugs that have well-documented and controlled evidence of teratogenicity in humans. The potential risk of category X drugs is considered to always outweigh the potential benefits. So, this one example is a very poor one, since the woman was taking a DIFFERENT drug that has been proven to cause deformities.
So, apparently all modern medicine has to offer us in terms of information on the safety of amphetamine while pregnant:
"If you take a whole bunch of it, like, enough to make you almost die, it will probably hurt your child. And one time a woman took it and also ate pills labeled 'These will deform your child', and she ended up with a deformed child!"
