Serum was collected before the operation and weekly for one month afterwards. Canine ELISA kits were used for hormonal assays. The male testosterone (T), interstitial stimulating hormone (ICSH) and the spermatogenesis stimulating hormone (SSH) showed a significant (P<0.01) decrease after the operation with high correlation to time. The female oestrogen (E2), progesterone (P4), prolactin (PRL) and follicular stimulating hormone (FSH) also had a significant (P<0.01) level decrease with high correlation to time post-operation unlike the luteinizing hormone (LH).
