Abstract
Orchiectomy is a common procedure in domestic feline (Felis domesticus) population management. In specific cases, it is complemented by epididymal salvage of sperm. The relationship between testicular morphology and epididymal spermatozoa quality remains relatively unexplored in domestic feline reproductive biology in Malaysia. The objective of this study was to identify the relation of testicular morphological characteristics with epididymal spermatozoa quality in domestic cats. Twenty three pairs of testes from castrated cats from four small animal clinics were obtained through convenience sampling. The age, breed, and testicular measurements (length, width, and thickness) were recorded. The testis volume was calculated using Lambert’s formula (L x W x T x 0.71). The correlation between the testicular morphology and spermatozoa quality were analysed using Pearson’s correlation test and Kendall tau-B’s test (IBM® SPSS Statistic 26). The results overall showed a non-significant (p>0.05), positive correlation between testicular morphology and sperm general motility, wave pattern, percentage of live sperm and total sperm count. For the left testes, there was a non-significant (p<0.05) positive correlation between testicular volume and general motility (r=0.147), wave pattern (r=0.241), percentage of live sperm (r=0.115) and total sperm count (r=0.212) respectively. For the right testes, there was also a non-significant (p>0.05) positive correlation between testicular volume and general motility (r=0.003), wave pattern (r=0.085), percentage of live sperm (r=0.161) and total sperm count (0.043) respectively. The width of the left testes had the highest correlation (r=0.832) with testicular volume. For the right testes, the thickness of the testes had the highest correlation (r=0.610) to testicular volume. In summary, the results showed that higher testicular volume had higher spermatozoa quality. These findings provide a foundational understanding for optimising post-orchiectomy epididymal salvage procedures in domestic cats, enhancing feline reproductive science, and facilitating improved reproductive health and breeding practices.
