mothers, even mothers who don't carry all the way to birth, get fetal cells, very similar to stem cells, that protect and repair their mothers, but can also trigger autoimmune conditions like lupus, or rheumatoid arthritis.

- EGreg 9y agoApparently I was wrong - according to this https://www.ncbi.nlm.nih.gov/m/pubmed/16510865/ https://www.ncbi.nlm.nih.gov/m/pubmed/16510865/ But this study is contradicted by many studies https://www.scientificamerican.com/article/having-sons-can-shorten-a-woman-life/ https://www.scientificamerican.com/article/having-sons-can-s...
- thrownblown 9y agothe radiolab is from 2012, and i'm sure they've learned a lot since then, but they do mention that there are a lot of factors (sex of children, number of children, number of fathers) that correlate with both good and bad effects of the fetal cells.

- thrownblown 9y agoThe simple answer is its complicated. Having a child is stressful on the organism, but there are ultimately 2 types of stress eustress and distress. Sometimes it's good sometimes it's bad. ¯\_(ツ)_/¯
