Is Chestnut really smell like sperm? Or it's just me??

Hi..!

Whenever I talk about plants, it's just remind me a very embarrassed moment in my life! I remember walking down a road along with few chestnut trees. And suddenly its just overwhelm with smell of semen! This couldn't be right. Then I've read that chestnut contain ingredient called spermindine, which is also can be found in sperm to keep the sperm survive. Is there any trees that has a very unpleasant and strong smell other than chestnut trees??? Could be an interesting topic for a research!
