Since its discovery some 80 yr ago, many advances have been made in understanding the many diverse roles of vitamin A (retinoids). Among these are the critical roles that vitamin A plays in regulating reproduction in both the male and female. The identification of retinol-binding proteins produced by the pig uterus and conceptus marks an exciting event. It will be pivotal to future efforts in elucidating the mechanism by which retinoids regulate conceptus development and steroidogenesis. However, relatively little is known of the possible direct role played by its provitamin, beta-carotene, in controlling reproduction in the pig. However, future research likely will address this aspect of carotenoid function.
自约80年前维生素A（类视黄醇）被发现以来，在理解其众多不同作用方面已取得了许多进展。其中包括维生素A在调节雄性和雌性生殖方面所起的关键作用。猪子宫和孕体产生的视黄醇结合蛋白的鉴定是一个令人兴奋的事件。这对于未来阐明类视黄醇调节孕体发育和类固醇生成机制的努力至关重要。然而，对于其维生素原β-胡萝卜素在控制猪繁殖方面可能发挥的直接作用，人们了解得相对较少。不过，未来的研究可能会涉及类胡萝卜素功能的这一方面。
