There's a gene, it's called SHBG. Sex Hormone Binding Globulin. When your liver breaks down sugar and certain artificial sweeteners, it deactivates the SHBG gene, leading to lower sexual hormone levels.

For you, that leads to a lower libido or even total erectile dysfunction.

For women, that can lead to infertility, uterine cancer, or polycystic ovaries.

Have you ever noticed a... lack of desire a few hours after ingesting high levels sugar? Perhaps while you're crashing?
