MORAIS, D.B. et al. Microscopy and morphometry of tubular components of rabbit testis supplemented with royal jelly. Arq. Bras. Med. Vet. Zootec. [online]. 2012, vol.64, n.4, pp.810-816. ISSN 1678-4162. http://dx.doi.org/10.1590/S0102-09352012000400004.
This study aimed to investigate the effects of royal jelly on spermatogenesis in rabbits treated with different concentrations of RJ (Control; 0,5mg/day; and 1,0mg/day) using testicular morphometry. There was no significant difference between the body weight (T1= 3.20±0.19kg; T2= 2.96±0.30kg; T3=3.21±0.37kg) and gonadal weight (T1= 2.36±0.33g; T2= 2.53±0.33g; T3= 2.64±0.39g), gonadossomatic index (T1= 0.15±0.02%; T2= 0.17±0.03%. T3= 0.16±0.02%) and tubulossomatic index (T1= 0.06±0.01%; T2= 0.07±0.01%. T3= 0.06±0.01%) between treatments, showing that the percentage of body mass, and the percentage of seminiferous tubules allocated in testis were similar in the 3 experimental groups. Similarly, the mean diameter of the seminiferous tubules (T1= 225.95±13.27µm; T2=239.68±21.50µm; T3= 231.57±15,94µm), the height of the seminiferous epithelium (T1=66,05±5,37µm; T2=73.47±9.11µm; T3=63.34±4.79 µm) and length of seminiferous tubule for testis (T1=46.63±13.44m; T2=43.58±12.17m; T3=46.96±9.54m) and per gram of testis (T1=19.50±2.68m; T2=17.12±3.91m; T3=17.78±1.98m) did not differ statistically. It was concluded that supplementation with royal jelly, at the doses used, did not alter the testicular parameters evaluated here.
