Figure 6.

Relative quantity of morphologically normal sperm cells in cats immunized with phage–gonadotropin-releasing hormone. Semen collection was accomplished by electroejaculation under general anesthesia. The morphologic analysis was performed using eosin–nigrin stain evaluating 100 cells/sample for defects. Relative numbers (%) of normal cells for individual cats prior to and post-immunization (monthly) are shown. Data are presented as group means ± SD. P <0.05 is noted with an asterisk. P value refers to post-treatment vs pretreatment. (a) Group 1; (b) Group 2; (c) Group 3
