Abstract
Viable koala spermatozoa were successfully collected from 8 of 11 capt ive Queensland koalas on 52 of 76 attempts using electroejaculation un der general anesthesia. Semen characteristics, including sperm concent ration, percent progressive sperm motility and nuclear heterogeneity a ppeared to be similar to those of free-ranging Victoria koalas (P.c. v ictor). Two new head morphotypes (Type XI and teratoid) were identifie d, and the incidence of midpiece and principal piece spermatozoal abno rmalities were recorded.
