Search “does creatine increase testosterone” and you’ll land on gym forums, TikTok clips, and conflicting supplement blogs. For most men, the answer is no. But one small 2009 study keeps the myth alive, and a 2025 trial finally asked the question that matters more for anyone trying to conceive: does creatine change your sperm.<\/p>\n

Does creatine raise testosterone?<\/h2>\n

Thirteen studies have tested creatine against testosterone levels, covering 278 participants combined. Of those, ten studies, involving 218 men, found no change at all. Meanwhile, three studies, with 60 participants between them, reported a small increase. Overall, a 2021 review published in the Journal of the International Society of Sports Nutrition<\/a> found creatine doesn’t raise testosterone in most people. That’s because creatine supports energy metabolism in muscle cells rather than manipulating hormones. So any testosterone bump lifters notice usually traces back to the resistance training itself, not the supplement.<\/p>\n

The DHT study everyone cites<\/h2>\n

The idea that creatine spikes DHT traces back to a single 2009 study of 20 college rugby players<\/a>. In that study, researchers gave the group 25g of creatine daily for a week, then 5g daily for two more weeks. DHT rose 56% after the loading week and stayed 40% above baseline through the maintenance phase, though testosterone itself didn’t move.<\/p>\n

However, no one has replicated that result in over fifteen years. What’s more, the creatine group started with DHT levels 23% lower than the placebo group before starting the supplement, which raises real questions about whether the two groups were comparable to start with. Later, a separate 12-week randomized trial set out to test the same DHT question<\/a>, this time looking at hair follicle health, and found no difference in DHT levels or the DHT-to-testosterone ratio between creatine and placebo groups. In short, the study behind the myth remains an outlier.<\/p>\n

What the actual sperm research shows<\/h2>\n

Until recently, no one had tested creatine directly on human semen. That changed in October 2025, when researchers ran the first controlled trial measuring whether creatine changes sperm quality itself<\/a>, rather than proxy hormone levels.<\/p>\n

The team gave 15 men creatine, creatine plus ubiquinol, or a placebo for eight weeks. Five of those men had low sperm counts (oligospermia) at baseline. Here’s what they found:<\/p>\n
