AYALA GUANGA, Luis E et al. Influence of Penis Spicule of Cavy (Cavia porcellus) on their Sexual Behavior, Fertility and Sperm Quality. Rev. prod. anim. [online]. 2017, vol.29, n.3, pp. 36-42. ISSN 2224-7920.

This research took place in canton Cuenca, province of Azuay, Ecuador, located on UTM 717 386 x 967 5751, 2 714 meters above sea level, with a mean temperature of 14 °C . This study determined the influence of penis spicules on sexual behavior, fertility and sperm quality parameters in cavy (Cavia porcellus), raised on the Ecuadorian highlands. A number of 5 whole males (with penis spicules) were included in the study. Also, included were 5 males with their spicules removed, and 40 multiparous females, conformation type A, pelage type 1. The pregnancy percentage of females that copulated with extirpated males decreased 65 % in relation to the control group (P < 0.05). However, the sexual behavior pattern and sperm quality of the two groups in the study were similar (P > 0.05). Therefore, the study concluded that extirpation of the penis spicule has effects on fertility, but not on sexual behavior and sperm quality.
