The reproductive cycle of the Namibian striped skink is described from a histological examination of gonadal material from museum specimens. Males followed a seasonal testicular cycle in which sperm were produced primarily during spring and summer. Testes in regression were present mainly in March. Females with oviductal eggs or corpora lutea were present September to March and May to June. Not all females reproduced annually. Clutch (= litter size) for 23 females was 4.9 + 0.97 S.D., range: 3-6. Keywords: Trachylepis sparsa, Scincidae, Reproductive cycle, Southern Africa.
