Sperm counts worldwide are plummeting faster than we thought
I did my Master Degree in Organic Chemistry where we tried to develop a male contraceptive pill. I spend a lot of time studying sperm so here is a short list of thing to avoid regarding sperm quality (not ranked):1. Eating and drinking from plastics (This includes aluminum cans which are plastic lined) [a]2. Heating food in ANY type of plastic [a]3. Caffein intake [b]4. Sugar intake [c]5. NOT exercising regularly [d]6. Alcohol [e]7. Age [f]8. Stress [g]9. Soy products or other natural products containing phytoestrogens [h]I edited the comment to add point 8 and 9.Funnily enough these goes for both genders regarding fertility. If you are considering having a child, it takes approximately 7 months for sperm to fully develop so better to change lifestyle sooner rather than later.a. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3222987
