Finasteride for pregnant guinea pigs

TL;DR: They used finasteride to reduce allopregnanolone levels in the uterus of pregnant guinea pigs. After birth, female offspring exposed to finasteride had more anxiety.

Conclusion: “…an intrauterine reduction in the supply of allopregnanolone programs vulnerability of female offspring to anxiety-like disorders in juvenility without impacting long term allopregnanolone concentrations.”
