Semen was collected by a standardized electroejaculation procedure from a giant panda on 4 occasions. Ejaculate volume, sperm count and % sperm motility were 2.3-3.6 ml, 62-562 x 10(6) spermatozoa/ml and 45-85%, respectively. The results, although limited to a single male, suggested a seasonal influence on ejaculate and gonadal parameters with improved ejaculate volume, sperm motility and increased testicular size in the season proximate to the female's oestrous period. Frozen-thawed spermatozoa were motile with no apparent abnormalities induced by the freezing procedure.
通过标准化的电刺激采精程序，在4个不同时间从一只大熊猫采集精液。射精量、精子计数和精子活力百分比分别为2.3 - 3.6毫升、62 - 562×10⁶个精子/毫升和45 - 85%。尽管结果仅来自单一雄性大熊猫，但表明射精和性腺参数存在季节性影响，在接近雌性发情期的季节，射精量、精子活力有所改善，睾丸尺寸增大。冻融后的精子具有活力，冷冻程序未引起明显异常。
