The sex ratio of a population is a major determinant of the population's survival and the reproductive success of individuals within the population. The ability of an individual to adjust the sex ratios of the offspring they produce, or to change their sex at the adult level such that the number of males and females at the population level are influenced, is a powerful concept and one that has been discussed in an evolutionary context for decades. Although for some systems, such as reptiles and some fishes, the mechanisms by which sex can be altered through environmental cues have been addressed in detail, in other systems, such as birds and mammals, surprisingly little is known about the mechanisms of sex ratio adjustment. This symposium will bring together researchers studying hormonal mechanisms of sex adjustment in birds, reptiles, fishes, humans, and non-human mammals in an effort to stimulate new research avenues in the study of sex ratio adjustment. By demonstrating novel approaches in their own vertebrate systems used to address similar questions about sex ratio adjustment, we will encourage cross-fertilization of ideas among speakers and introduce the SICB audience to potential research avenues to which their current research in their respective systems could prove applicable. The symposium will include presentations by nine speakers, including one assistant professor, two associate professors, five professors, and one senior lecturer. Three of the nine speakers are women and three are foreign nationals. Efforts were made to include those with the highest level of expertise in the field of hormone-mediated sex ratio adjustment, while stimulating (1) interactions between foreign and US researchers, (2) interactions between young scientists and established scientists, and (3) incorporation of underrepresented groups at the nexus of hormone-mediated sex ratio adjustment in multiple vertebrate systems.

一个种群的性别比例是种群生存和种群内个体繁殖成功的主要决定因素。一个个体调整其后代性别比例的能力，或者在成年阶段改变其性别，从而影响种群中的雄性和雌性数量的能力，是一个强大的概念，几十年来一直在进化背景下讨论。虽然对于某些系统，如爬行动物和某些鱼类，性别可以通过环境线索改变的机制已经详细讨论，但在其他系统中，如鸟类和哺乳动物，令人惊讶的是，对性别比例调整的机制知之甚少。本次研讨会将汇集研究鸟类，爬行动物，鱼类，人类和非人类哺乳动物性别调节的激素机制的研究人员，努力激发性别比例调节研究的新研究途径。通过在他们自己的脊椎动物系统中展示用于解决性别比例调整的类似问题的新方法，我们将鼓励演讲者之间的思想交流，并向SICB观众介绍他们目前在各自系统中的研究可能适用的潜在研究途径。 研讨会将包括九位演讲者，包括一位助理教授，两位副教授，五位教授和一位高级讲师。九名发言者中有三名妇女，三名外国人。努力包括那些具有最高水平的专业知识，在该领域的胚胎介导的性别比调整，同时刺激（1）外国和美国研究人员之间的互动，（2）年轻科学家和建立科学家之间的互动，（3）在多个脊椎动物系统中的胚胎介导的性别比调整的关系中纳入代表性不足的群体。
