Abstract

The size, weight and volume as well as the sperm content of the testes of 18 mature, 6-10-year-old camels with unknown breeding history were determined after slaughtering and then related to one another. It was found that the weight and the volume of the testes can be estimated fairly accurately by means of their length. The length of the testes can also be used to calculate the sperm reserves, although more accurate values can be obtained by taking the square numbers of the testes length, breadth, and thickness into account. The average values for gonadal and epididymal sperm reserves of paired testes and epididymides was 6.278 +/- 1.226 X 10(9) and 12.177 +/- 2.316 X 10(9) respectively. The sperm production per gram testes tissue was 40.55 +/- 15 X 10(6).

摘要

对18头6至10岁、繁殖史不明的成年骆驼宰杀后测定其睾丸的大小、重量、体积以及精子含量，并将这些指标相互关联。结果发现，睾丸的重量和体积可以通过其长度较为准确地估算出来。睾丸长度也可用于计算精子储备量，不过若将睾丸长度、宽度和厚度的平方数考虑在内，能得到更精确的值。成对睾丸和附睾的性腺及附睾精子储备的平均值分别为6.278±1.226×10⁹和12.177±2.316×10⁹。每克睾丸组织的精子生成量为40.55±15×10⁶。
