对许氏猪齿鱼的年生殖周期和性别进行了组织学研究。主要的产卵期从2月持续到5月，在最活跃的时期，即3月和4月，几乎每天都有个体产卵。获得了TL与繁殖力和批量繁殖力的关系。C. Schoenleinii在24 cm TL左右成熟为雌性，表现出雌雄同体的单雌性。性别转换发生在40-64 cm TL，所有大于65 cm TL的鱼都是雄性。C. Schoenleinii是接近性二色的，身体颜色从最初的绿黄色阶段（雌性）到最终的蓝色阶段（雄性），几乎完全符合性别转变。
The annual reproductive cycle and sexuality of Choerodon schoenleinii were studied histologically. The major spawning period persisted from February until May, spawning of individuals occurring almost every day during the most active period, being March and April. Relationships between TL and both Fecundity and batch fecundity were obtained. C. schoenleinii mature as females at about 24cm TL and exhibit protogynous hermaphroditism with monandric sexuality. Sex transition occurred from 40-64 cm TL, all fish larger than 65 cm TL being males. C. schoenleinii is closely sexually dichromatic, the body color changing from an initial greenish-yellow phase (female) to a terminal blue phase (male), in almost complete accordance with the sex transition.
