Thread Name: BS: Who remembers Thalidomide?
Subject: RE: BS: Who remembers Thalidomide?
Well, maybe I remembered wrong.

"Thalidomide causes damage to the forming embryo in a short time sensitive window also known as the “critical period.” The time sensitive window extends between days 20 and days 36 after fertilization (34–50 days after last menstrual cycle;"

You can find the source by copying this and googling it.
