Interactions of methyl farnesoate and related compounds with a crustacean retinoid X receptor
Molecular and Cellular Endocrinology, 309(1-2), 109–116.
author keywords: RXR; EcR; Methyl farnesoate; Daphnia; Tributyltin

Observations of imposex and free testosterone levels were elevated in field collected snails containing high tin levels, while testosterone-fatty acid ester pools were reduced in these organisms, indicating that tributyltin elevates free testosterone by reducing the retention of testosterone as fatty acid-esters.

Endosulfan elevates testosterone biotransformation and clearance in CD-1 mice
TOXICOLOGY AND APPLIED PHARMACOLOGY, 148(1), 158–168.

TL;DR:
Results indicate that increases in testosterone biotransformation from endosulfan exposure can result in increases in the elimination of the steroid, however, homeostatic processes apparently compensate for the effect and minimize any consequences on serum hormone levels.

MeSH headings : Animals; Aryl Hydrocarbon Hydroxylases; Chorionic Gonadotropin / pharmacology; Cytochrome P-450 Enzyme Inhibitors; Cytochrome P-450 Enzyme System / genetics; Estrenes / pharmacology; Gonadotropin-Releasing Hormone / pharmacology; Hypothalamus / drug effects; Hypothalamus / physiology; Liver / enzymology; Male; Metribolone; Microsomes, Liver / enzymology; Orchiectomy; Pituitary Gland / drug effects; Pituitary Gland / physiology; Polychlorinated Biphenyls / pharmacology; RNA, Messenger / metabolism; Rats; Rats, Inbred Strains; Steroid 16-alpha-Hydroxylase; Steroid Hydroxylases / metabolism; Testis / drug effects; Testis / physiology; Testosterone / blood
TL;DR:
The present study demonstrates that the consequential reduction in serum testosterone levels in HCB-treated rats is not causally related to the reduction in hepatic P450 2c levels, indicating that HCB must also act on some other regulatory mechanism involved in the expression of this protein.

Adult male-specific and neonatally programmed rat hepatic P-450 forms RLM2 and 2a are not dependent on pulsatile plasma growth hormone for expression
The Journal of Biological Chemistry, 263(23), 11396–11406.
TL;DR:
Rat hepatic cytochrome P-450 form RLM2 is a testosterone 15 alpha-hydroxylase reported to be male-specific on the basis of purification studies and its adult male- specific expression is imprinted (programmed) in response to neonatal testosterone exposure.

Feminization of rat hepatic P-450 expression by cisplatin. Evidence for perturbations in the hormonal regulation of steroid-metabolizing enzymes
The Journal of Biological Chemistry, 263(30), 15732–15739.
TL;DR:
The studies establish that the effects of cisplatin on hepatic P-450 enzyme expression result from its interruption of the hypothalamic-pituitary stimulation of testicular androgen production and that this, in turn, leads to a depletion of circulating androgens required for maintenance of normal P- 450 enzyme expression in adult male rats.

TL;DR:
It is suggested that in fact all of these compounds act in a similar manner internally to modulate enzyme activity, and that apparent differences in activity are a reflection of differences in bioconcentration of the different compounds.
