Abstract


The purpose of this study was to assess the relationship between the anogenital distance measures on certain reproductive parameters such as scent marking, sexual satiety, and testosterone level. A total of 34 animals (22 rabbit bucks and 12 primiparous females) aged 6 and 7 months and with an average weight of 3458 g were used. Rabbit bucks went a behavior assessment (scent marking and sexual satiety) and blood sampling. The results indicated a mean measured anogenital distance of 22.98 ± 1.98 mm. 54.55% of the males had an anogenital distance higher than the mean anogenital distance whereas 45.45% had a lower anogenital distance. The anogenital distance, has influenced on scent marking, sexual satiety and testosterone level. Our results indicated that there is a very significant difference in the scent marking and sexual satiety and a highly significant decrease in scent marking (72.74%; p = 0.007) after satiety (51 vs 14). Males with a high number of mounting during sexual satiety test (4 to 13) had a high plasma testosterone level compared to less mounting (1 to 3) (9.75-13.5 vs 2.57-11.33ng /mL). Males with high anogenital distance have elevated testosterone levels (≥13.5 ng /mL). Our results suggest that a longer anogenital distance may predict normal male reproductive potential.
