Does nicotine cause infertility?

Nicotine does not cause infertility in humans. While it does have this effect on certain insects due to its capacity to disrupt their nervous system, it does not have the same impact on human fertility. However, Andrew Huberman mentions that nicotine can lead to certain forms of sexual dysfunction, primarily through changes in blood flow and endothelial cell function, but it does not render humans infertile 1.
