Immunoreactive luteinizing hormone-releasing factor (LRF) was quantitated in the human placenta. It was found that the total placental content as well as the content per milligram of placental tissue varied with the stages of gestation. The fetal sex did not affect the LRF production. These studies establish that the placenta contains large amounts of LRF, immunologically identical to hypothalamic LRF.
对人胎盘组织中的免疫反应性促黄体生成素释放因子（LRF）进行了定量分析。结果发现，胎盘组织中的LRF总量以及每毫克胎盘组织中的LRF含量均随妊娠阶段而变化。胎儿性别并不影响LRF的产生。这些研究证实，胎盘含有大量与下丘脑LRF免疫特性相同的LRF。
