Thyroid hormones, acting via their cognate thyroid receptors (TRs) act as mediators and
modulators of several physiological processes and homeostasis. A clear role for the TRs in
reproduction has not yet been established although several lines of recent evidence suggest
that they are involved in the regulation of reproduction. To further study the role of TRs in
control of reproduction, we investigated homologous regulation of TR subtypes in the
gonads of goldfish, in vivo and in vitro. It was found that tri-iodothyronine (T3) down …
