Objectives Gonadotropin-releasing hormone (GnRH) agonists like deslorelin are being increasingly used in tom cats for their efficacy in controlling reproductive behaviour and fertility. Deslorelin implants have been widely available in Europe since 2008. Little, if anything, is known about the interval between treatment and onset of sterility, as well as semen quality, after treatment in tom cats. The purpose of this study was to investigate semen quality and interval to sterility in tom cats treated with a 9.4 mg deslorelin implant. Methods Fifteen healthy adult tom cats were treated with a 9.4 mg deslorelin implant (Suprelorin 12). For each cat, semen collection and a GnRH stimulation test (intramuscular administration of 50 μg gonadorelin [Fertagyl], followed by blood sampling 1 h later, to assay serum testosterone) were performed on the first consultation and then repeated every 15 days until complete sterility was achieved. Semen collection was performed by introducing a 14 cm, open-end feline catheter (Argyle) 9 cm into the distal urethra 10 mins after sedation by intramuscular injection of 100 μg/kg medetomidine (Domitor). Results Semen collection was not successful in all cats at each attempt. In the first month after treatment, the semen of only four cats could be evaluated, while the semen of eight cats could be evaluated during the second and third months of the study. Semen quality (ejaculate volume, progressive motility and morphological abnormalities) improved slightly during the first 19–25 days in 2/4 cats, and in 1/4 cats motility was still very high (80%) 25 days post-treatment (PT), but we have no data regarding fertility prior to treatment in this cat. The last cat never produced spermatozoa. Subsequently, semen quality gradually worsened in all cats from 30 days onwards. At 70 days PT, one cat was still potentially fertile. After 72 days all cats were sterile. Conclusions and relevance Semen quality increased slightly in treated cats during the first month after treatment, and then gradually decreased over the following months. Complete sterility was reached within 40–72 days following implantation.

Two Independent Variables

203 female Ss read a short case-study and a group of related questions. They were then required to complete a 12 adjective-pair semantic differential indicating their dispositional judgments of the stimulus person in the narrative. Two independent variables were manipulated, the sex of the stimulus person and the group of questions asked. One group of questions was intended to induce a situation-matching set and the other a causal-genetic set. Ss in the situation-matching group rated the male stimulus person more hard ( p < .05), more bold ( p < .01), and less emotional ( p < .05) than Ss in the causal-genetic group. In the case of the female stimulus person Ss in the situation-matching group perceived her as more bold ( p < .05). Differences due to sex alone were found only for the situation-matching groups who perceived the female stimulus person as less hard ( p < .05) and less rugged ( p < .01) than the male.
