The benefits of consuming Royal Jelly is getting a lot attention recently by the medical profession, reknown for centuries, and now found to contain essential nutrients for living beings. Studies have proven its effect as a 'Brain Booster', lowering cholesterol and now its capacity to boost sperm count in mammals. Royal Jelly contains life force and is a life giver...
Seminal quality and testicular morphometry of rabbits (Oryctolagus cuniculus) supplemented with royal jelly
Arq. Bras. Med.Vet. Zootec, 2012, Dec.
A trial was carried out to evaluate the effects of royal jelly on the seminal quality and testicular morphometry of rabbits.
Fourteen mature rabbits of New Zealand breed were distributed between three groups. The first group was supplied with 1mL of water only (SG), the second group was supplied with 0.5mg of royal jelly diluted in 1mL of water (0.5G), and the third group was supplied with 1mg of royal jelly also diluted in 1mL of water (1.0G).
The royal jelly supply started 30 days before semen collection and lasted the entire experimental period. An artificial vagina was used to collect the rabbits' semen. Physical and morphological parameters in the semen and the testicular morphometry were evaluated. Differences were found on the seminal volume in group 0.5G(0,54±0,22) in relation to SG (0,39±0,13) and 1.0G (0,30±0,09) groups (P < 0.05). For SG, 0.5G and 1.0G groups, no differences (P > 0.05) were found in sperm concentration, gross motility, individual motility and vigor. The total of primary defects in group 0.5G (8,52±3,26) was lower than in groups SG (14,09±4,2) and 1.0G (16,1±3,95) (P < 0.05). No significant difference was found between secondary defects and the total defects on the semen (P > 0.05).
Body, testicular and epididymal weights did not differ between groups, as well to the gonadosomatic index (P > 0.05). The ingestion of royal jelly produced positive results on the seminal production of males.
Royal jelly is composed of 63% moisture, 3.5% lipids (steroids), 13% protein and 19.5% carbohydrates, minerals, and vitamins (thiamine, riboflavin and niacin) (Amoedo and Muradian, 2002) and other yet unidentified components (Kohno et al., 2004). The acid 10-hydroxy-2-decenoic (10-HDA) is the main component of its lipid fraction and is considered the most important active ingredient of royal jelly (Koshio and Muradian, 2003)...
CONCLUSIONSThe daily intake of 0.5 mg of Royal Jelly increased semen volume and decreased values sperm defects in primary New Zealand rabbits, with positive effects on the morphology seminal.
