The hypothalamic hormone gonadotropin-releasing hormone (GnRH) has been found in milk of man, cow, and rat. Radioimmunoassays of acidified milk indicate concentrations of GnRH ranging between 0.1 and 3 nanograms per milliliter. Multistep extractions, followed by electrophoresis, reveal gonadotropin-releasing activity in the fraction that comigrates with the GnRH-marker. A second hypothalamic hormone, thyrotropin-releasing hormone, is present in milk at a much lower concentration. "Milk -GnRH" may influence the secretion of the gonadotropic hormones in neonates.
已在人、牛和大鼠的乳汁中发现下丘脑激素促性腺激素释放激素（GnRH）。对酸化乳汁进行放射免疫分析表明，GnRH的浓度在每毫升0.1至3纳克之间。经过多步提取，然后进行电泳，发现在与GnRH标记物一同迁移的组分中存在促性腺激素释放活性。另一种下丘脑激素促甲状腺激素释放激素在乳汁中的浓度要低得多。“乳汁中的GnRH”可能会影响新生儿促性腺激素的分泌。
