November 2009 in “General and Comparative Endocrinology” The researchers reported that during early embryogenesis and larval development in Silurana tropicalis, inhibiting steroidogenic enzymes cyp19 and srd5beta affects genes related to thyroid and reproductive systems.

January 2009 in “Sexual Development” This study found that chronic exposure to fadrozole or finasteride during frog development induced intersex individuals, which displayed different gene expression profiles depending on the chemical used.

December 2009 in “Developmental Neurobiology” In this study, the authors concluded that androgens, but not estrogens, strictly mediate the maintenance of neuromuscular morphology in the spinal nucleus of the bulbocavernosus in adult rats.

January 2011 in “Sexual Development” This study observed that chemically-induced intersex frogs displayed altered brain mRNA profiles, with finasteride increasing certain hormone-related gene expressions and fadrozole reducing aromatase activity without affecting gene transcript levels.

April 2010 in “Comparative Biochemistry and Physiology Part C Toxicology & Pharmacology” This study found that exposure to sex steroid biosynthesis inhibitors increases the expression of piRNA pathway genes in frog larvae, suggesting these genes play a role in gonadal sex differentiation.
