摘要

This study was conducted to measure the level of hormonal dropping after surgical gonadectomy in male and female dogs, six male and six female dogs were used, the orchidectomy and ovariectomy were done to these animals after one month of quarantine in cages in at the College of Veterinary Medicine-University of Baghdad in April 2016. 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). Results revealed that the surgical gonadectomy was safe and preferable for dogs’ contraceptive and the male and female hormones dropped quickly after the gonadectomy.
