I have a research paper on Teratogens, the one I have chosen is Aspirin. I haven't had any luck finding specific details on Aspirin as a teratogen so if you have any information that would be useful then I would really appreciate it!

As far as I am aware, aspirin is not considered a teratogen. Its main side-effect is inhibition of blood clotting, which can be either bad or good depending on what other medical conditions you have. It is a risk factor for contracting Reye's syndrome (a particularly nasty complication of chicken pox, I think). I've never heard that it causes birth defects, though.

I am not sure aspirin IS a teratogen, but you can find out quickly by doing a web search on the term "aspirin teratogen" on

Hi Stephani,

Interesting subject! I did not know that aspirin was thought to be teratogenic. If you go to PubMed online ( you can search the scientific literature for any subject related to biomedical issues. They provide the abstracts of most publications. I did a search for 'aspirin, teratogen' and found a few interesting articles on animal models in which the teratogenicity of aspirin (acetyl salicylic acid) was determined. You can check for yourself. Another great site is TERIS, a database on teratogenic agents which has a special on aspirin. See
