This research is awe inspiring in its brilliance. The fact that humans had this perverse reaction to it is absolutely fascinating to me. And it is in a service to a greater cause. I am happy that this work was done. We need to do more! edit: This comment is positive on purpose. The default pessimism in these comments is unwarranted. And the research has a lot of potential. Some foreseeable. Some not. For e.g., A lot of comments are making remarks such as, "it just shows male blood is detrimental to pregnancy." However, this isn't what the research shows. The research demonstrates that certain proteins are required to sustain the pregnancy. That's a fairly remarkable insight. Isolating these proteins, specifying them, and then attempting to measure the precise amounts of these should help to reduce miscarriages of intentional pregnancies in our species. That's an amazing development. It's a useful model with significant applications.
