A little bit of Royal Jelly increases testosterone level by 20 percent
The first group used honey containing 100 mg Royal Jelly. The second group used honey with 50 mg Royal Jelly, and the amount for the third group was 25 mg. The fourth group used honey without Royal Jelly. The supplementation lasted for 3 months. The study does not mention which sort of Royal Jelly was used.
Although the men did not produce more spermatozoa as a result of the supplement, the Royal Jelly did increase the activity of the spermatozoa. The first table included below shows that the percentage of moving spermatozoa increased as a result of the supplement.
Royal Jelly increased the production of the stimulating hormones FSH and LH by some tens of percent. The second table shows the effect on the concentration of LH.
As shown above, Royal Jelly increased the concentration of testosterone by 20 percent. Twenty percent may not seem like much, but you only need 25 mg Royal Jelly a day to realise this effect.
Chinese researchers at Nanchang University published an animal study a few weeks ago in which daily doses of Royal Jelly of some hundreds of milligrams per kg of body weight had undesirable hormonal effects. [Food Chem Toxicol. 2012 Jun;50(6):1834-40.]
