促卵泡激素β亚基（英语：Follitropin subunit beta 或 follicle-stimulating hormone beta subunit 缩写FSH-B）是一种由人类基因 编码的蛋白质 。其RNA的选择性剪接可形成该蛋白的两种蛋白异型体。
垂体糖蛋白激素家族包括促卵泡激素、黄体生成素、人绒毛膜促性腺激素和促甲状腺激素，所有这些糖蛋白激素都包括一个共同的α亚基和一个特异的β亚基。 基因编码的就是促卵泡激素的β亚基。 In conjunction with luteinizing hormone, follicle-stimulating hormone induces egg and sperm production.
