英文摘要	The present study consists on age-related analysis of reproductive activity in male dromedary camel from extreme arid area. Five reproductive traits of 20 bull camels were recorded and computer-assisted histomorphometric evaluation of 48 paired testes were performed to establish quantitative developmental pattern in relation to their respective age. The pubertal changes were displayed mainly at 4 to 5 years old with increased sperm reserves, seminiferous tubules volume, diameter and total length, high relative volume of interstitial tissue components, high individual Leydig cells volume and total number Leydig cells. At this age the first reductional miotic splits and first spermatids and spermatozoa in the seminiferous lumen tubules were significantly developed leading to increase the mean germ cells number and tubular fertility indexes. Animals in this age category showed the highest proportion of first mating (50%), while mating frequency and time were relatively higher. These reproductive traits were improved significantly with spermatogenesis efficiency in mature animals aged > 6 years old. The testicular spontaneous degeneration was observed in animals ages >= 13 years old. Our data showed long postnatal duration to onset spermatogenesis and endocrine compartment proliferation, that lead to delayed puberty (4 to 5 years), short duration of maximum activity (8 to 10 years) and early genital degenerative involution ( from 13 years).
