Caffeine decreases the testis volume and the number of spermatogenic cells in
seminiferous tubules of rat testis. Therefore, the aim of this study was to assess the impact of caffeine exposure
during pregnancy and lactation on seminal vesicle and epididymis in rat offspring.
Materials and Methods: In this experimental study, 21female pregnant rats were divided into control and
experimental groups (two groups). The experimental groups 1 and 2 received caffeine via drinking water during
pregnancy and lactation (26 and 45 mg/kg/bw, respectively). The structural changes in seminal vesicle and
epididymis were studied by using histological methods on day 120 of postnatal development (n=5, selected randomly
from each group). Data were statistically assessed by one-way ANOVA followed by Tukey’s post-hoc Test.
Results: The high dose caffeine treated group decreased the epithelium height of seminal vesicle compared with the
control group; however, the differences were not significant (p=0.909). The thickness of the muscle layer of the
seminal vesicles in the high dose caffeine treated group increased compared with the control group (p<0.001).
Significant decreases in epithelium height of tubules of the epididymis in the high dose caffeine treated group was
observed compared with the control group (p=0.047), and the diameter of the tubules of epididymis in the high dose
caffeine treated group decreased compared with the control group (p<0.001).
Conclusion: The results of this study showed high dose caffeine can induce histomorphological changes in the
seminal vesicle and epididymis of rat.
