January 2005 in “Brain Research” This study indicates that progesterone’s anesthetic activity in PR knockout mice is not due to progesterone receptors but is partially mediated by the neurosteroid allopregnanolone through GABAA receptor potentiation.

April 1998 in “American Journal of Dermatopathology” This study found no significant difference in estrogen and progesterone receptor expression between androgenic alopecia and alopecia areata, suggesting an indirect hormonal influence on androgenic alopecia.

November 2017 in “Experimental physiology” This study found that in newborn rats, progesterone's effects on apnoea frequency are influenced by a sex-specific balance between its metabolite allopregnanolone and progesterone receptors.

April 2020 in “Medico-Legal Update” This study found that phenolic extract from Hibiscus rosa-sinensis flowers significantly decreased testosterone, progesterone levels, and androgen receptor expression in male rats over 60 days.
