Episode notes
Menstruation Is An Evolutionary Filter
- Humans have spontaneous decidualization which thickens the womb lining before conception.
- This lets humans be selective about embryo implantation and protects high parental investment.
Selective Implantation Protects Maternal Investment
- Spontaneous decidualization actively chooses whether an embryo will implant.
- That selectivity is a survival advantage because humans invest heavily in pregnancy.
Reframe Periods As Positive Biology
- Reframing menstruation positively helps counter negative cultural views.
- Recognising it as an active species trait shifts how we value and discuss it.
