英文摘要	Our interest in the testicular study of the desert rodent, Gerbillus tarabuli, would provide a better comprehension of the seasonality of spermatogenesis in rodents. We thus performed a biometric, histomorphometric and statistical analyses in Gerbillus tarabuli sexually immature and adult during the annual reproductive cycle (active and regressed states of gonadal activity). For that, fixed testes were embedded in paraffin. Sections were stained using the modified Heidenhain Azan and then were subjected to morphometric measurements at the light microscopic level. The biometric study revealed a positive correlation between the body weight and the maturity state only, with an average of 20.8 +/- 2.92 g in sexually immature Gerbils, 37.40 +/- 1.86 g in the sexually quiescent adults (p < .01) and 40.40 +/- 2.98 g in the sexually active adults (p > .05), while the testes weight (sexually immatures = 0.02 +/- 0.003 g, sexually quiescent adults = 0.13 +/- 0.01 g; p p < .001) and the gonadosomatic index (sexually immatures = 0.09 +/- 0.02%, sexually quiescent adults = 0.36 +/- 0.04%; p p < .01) varied according to the maturity state and as well as to the season in the adults. Through the histomorphometric study, the tubular diameter showed a continuous increase from sexually immature Gerbils (72.83 +/- 7.57 mu m) to sexually quiescent adults (99.45 +/- 4.34 mu m) p < .05 then to sexually active adults (182.58 +/- 5.22 mu m); p < .001, this is explained by the appearance of a large lumen after puberty in the quiescent (26.32 +/- 1.28 mu m); p < .001 and the enlargement of the seminiferous epithelium in actives (75.11 +/- 1.81 mu m); p < .001. Besides, the nucleo-cytoplasmic ratio of Leydig cells (sexually immatures = 0.5 +/- 0.02) diminishes significantly after puberty in the rest period (0.42 +/- 0.03); p < .05 and then during the active period (0.24 +/- 0.01); p Gerbillus tarabuli testis between sexually immature Gerbils, sexually quiescent and active adults, follow the photoperiod-induced changes in endocrine and exocrine functions and prove that Gerbillus tarabuli is a useful model to study histo-physiological relationships in the testis in order to develop a more complete understanding of spermatogenesis phenomenon.
