Long-term dietary intake of excessive vitamin A impairs spermatogenesis in mice
Vitamin A when fed in excess to mice dramatically increased serum testosterone levels while nearly halting spermatogenesis. Of course one shouldn't overconsume vitamin A as there are quite a lot of side effects (including bone problems and of course damaged sperm production), however this study does imply that both Ray Peat and others on this forum are correct in recommending vitamin A for increased steroidogenesis.
Edit:
"Serum testosterone levels were significantly higher in VAE males (mean ± S.E.: 35.1 ± 16.4 ng/mL) than in control males (mean ± S.E.: 5.2 ± 1.8 ng/mL; P < 0.05;"
I had to re-read this several times to make sure 35.1 ng/mL was not a mistake. That's in the anabolic steroid range. Thats 3500 ng/dl. Its on the high end of even anabolic steroid use. I'm still convinced I'm misreading this.
