Target

GnRH Receptor[1]

In Vitro GnRH (10 μM) abolishes Buserelin-binding with GnRH Receptor[4].
In Vivo Gonadoliberin (50 ng, i.v.) promotes LH secretion in atrazine-treated rats[2]. Gonadoliberin (0.15 μg/min for 2 min every hour, i.v.) induces an LH discharge in agonadal juvenile male monkeys[3]. Animal Model: Atrazine (300 mg/kg)-treated rats[1] Dosage: 50 ng Administration: Intravenous injection (i.v.) Result: Reversed the suppression of the estrogen-induced LH surge of atrazine exposure.
