The luteinizing hormone-releasing hormone (LH-RH) system in neonatally estradiol-feminized male gray short-tailed opossums (Monodelphis domestica).
In this study, the luteinizing hormone-releasing hormone (LH-RH) system was examined in adult gray short-tailed opossums that had been treated with estradiol benzoate (EB) on days 1 and 3 of postnatal life, a treatment which results in complete block of testicular development. The finding that the organization of the LH-RH system in neonatally EB-treated males did not differ from that of neonatally untreated animals indicates that the LH-RH system can develop normally despite the absence of gonads throughout perinatal life.
