Résumé

Morphometric data of the reproductive organs and the gonadal and extra-gonadal sperm reserves were determined in sexually mature M'bororo bulls. The mean body weight was 560±15.8kg and measured 175.8±4.3cm at the withers. The mean paired testes weight and scrotal circumference were 266.5±28.9g and 28.2±0.8cm, respectively. The body weight was significantly and positively corellated with the testicular sperm reserves (P<0.05). The paired testicular sperm reserves was 27.3±3.1 *109. The mean weights of the accessory gland were: Seminal Vesicles, 42.2±4g; ampullae, 12.4±2.0g;Prostate gland, 2.2±0.29g and 1.3±0.3g for the bulbourethral gland. The mean penis lenght was 80.9±2.9cm while the glans penis and the urethral process measured 3.1±0.1cm and 1.9±0.1cm, respectively
