Sperm storage capacity of the indigenous West African boar.
The sperm reserves in the testis and epididymis of pubertal and adult indigenous West African boars were 4.22 and 4.99 x 10(9) and 1.81 and 1.92 x 10(9) respectively and were influenced by age and organ weight (P < 0.05). Although these values were much less than those of exotic boars of about the same age, distribution in weights and sperm content of both indigenous and exotic boars is similar. However, testicular and epididymal sperm reserves were unrelated (r = 0.19, P > 0.05) indicating that sperm storage capacity was still developing.
