Original Note:
Few trees have male or female sex. There is no indication that dioecious males are preferred in practice for urban planting, and little reason to believe their use would change pollen count regardless. https://slate.com/technology/2021/10/botanical-sexism-viral-idea-myth.html Rising pollen count may result instead from increasing temperatures: https://www.sciencedirect.com/science/article/pii/S2542519619300154
