In Schizothorax richardsonii, the pituitary gland has been studied in correlation with the phases of the testicular cycle. The cyanophils of the proximal pars distalis show hypertrophy, hyperplasia, granulation, degranulation and vacuolisation in concurrence with the spermatogenic cycle. Secretory activity of the cyanophils controls the maturation of testes, which indicates that these cyanophils are gonadotrops. The formation of sperm mother cells, however, does not appear to depend on the secretory activity of the pituitary. During spawning and regression phases, the azocarminophilous granules in the cytoplasm of the cyanophils show quantitative variation. The migratory chromophil cells show numerical variation, suggesting their involvement in the reproductive cycle. Neurosecretory material also appears to play some part in reproduction.
在高原裂腹鱼中，已对垂体与睾丸周期各阶段的相关性进行了研究。远侧部近端的嗜蓝细胞在生精周期的同时出现肥大、增生、颗粒化、脱颗粒和空泡化。嗜蓝细胞的分泌活动控制着睾丸的成熟，这表明这些嗜蓝细胞是促性腺激素细胞。然而，精母细胞的形成似乎不依赖于垂体的分泌活动。在产卵期和消退期，嗜蓝细胞胞质中的偶氮嗜染颗粒出现数量变化。迁移性嗜色细胞出现数量变化，表明它们参与了生殖周期。神经分泌物质似乎在生殖中也发挥了一定作用。
