基于古今文献系统阐释天癸概念、生理特性及生殖学意义，进一步梳理天癸贯穿男性生殖功能萌生、成熟、维持、失调及衰退全程的理论内涵。从其生理基础而言，天癸以肾精为基础，在脏腑协同下调节男性生殖功能，具有时限性、节律性、相对独立性、靶向性、功能多样性的特点。男性生殖疾病的发生与天癸失常密切相关，主要表现为天癸不足与天癸时序失调，临证治疗当遵循“补其不足、调其时序”原则，以恢复天癸正常运行节律。

Based on ancient and modern literature, this paper systematically elucidates the concept, physiological characteristics, and reproductive significance of tiangui （天癸）, and further reviews its theoretical connotation throughout the entire process of male reproductive function, covering its onset, maturation, maintenance, disorder, and decline. In terms of its physiological foundation, tiangui is rooted in kidney essence and regulates male reproductive function through the coordination of zang-fu （脏腑） organs. It possesses characteristics of being time-limited, rhythmic, relatively independent, targeted, and functionally diverse. The occurrence of male reproductive diseases is closely related to the abnormality of tiangui, which primarily manifests as tiangui deficiency and dysregulation of tiangui timing. In clinical practice, treatment should follow the principle of "supplementing its deficiency and regulating its timing", so as to restore the operating rhythm of tiangui.
