Climate change is an incessant global phenomenon and has turned contentious in the present century. Malaysia, a developing Asian country, has also undergone significant vicissitudes in climate, which has been projected with significant deviations in forthcoming decades. As per the available studies, climate changes may impact on the fertility, either via direct effects on the gonadal functions and neuroendocrine regulations or via several indirect effects on health, socioeconomic status, demeaning the quality of food and water. Malaysia is already observing a declining trend in the Total fertility rate (TFR) over the past few decades and is currently recorded below the replacement level of 2.1 which is insufficient to replace the present population. Moreover, climate changes reportedly play a role in the emergence and cessation of various infectious diseases. Besides its immediate effects, the long-term effects on health and fertility await to be unveiled. Despite the huge magnitude of the repercussion of climate changes in Malaysia, research that can explain the exact cause of the present reduction in fertility parameters in Malaysia or any measures to preserve the national population is surprisingly very scarce. Thus, the present review aims to elucidate the possible missing links by which climate changes are impairing fertility status in Malaysia.
气候变化是一个持续存在的全球性现象，在本世纪变得颇具争议。马来西亚是一个亚洲发展中国家，其气候也经历了重大变迁，预计未来几十年将出现重大偏差。根据现有研究，气候变化可能会通过对性腺功能和神经内分泌调节的直接影响，或通过对健康、社会经济地位、食物和水质量的恶化等若干间接影响，对生育率产生影响。马来西亚在过去几十年中总生育率（TFR）呈下降趋势，目前已低于 2.1 的更替水平，这不足以替代现有人口。此外，气候变化据报在各种传染病的出现和停止中发挥了作用。除了其直接影响外，对健康和生育的长期影响有待揭示。尽管气候变化对马来西亚的影响巨大，但解释马来西亚目前生育率参数下降的确切原因或任何保护国家人口的措施的研究却少之又少。因此，本综述旨在阐明气候变化影响马来西亚生育率的可能缺失环节。
