Molecular mechanisms of libido influencing semen quality in geese through the hypothalamic-pituitary-testicular-external genitalia axis.

ABSTRACT: Libido plays a crucial role in influencing semen quality, yet the underlying regulatory mechanisms remain unclear. As a central axis in male goose reproduction, the hypothalamic-pituitary-testicular-external genitalia (HPTE) axis may contribute to the regulation of this process. In this study, we established a rating scale for goose libido based on average number of massages to erection (ANM) and the erection type, and evaluated semen quality across the entire flock. Correlation analyses showed that ANM was negatively correlated with sperm concentration (SC), acrosome integrity (AI), and semen quality factor (SQF), while positively correlated with morphological abnormal sperm (MAS) (P < 0.01). A comparison of semen quality and testicular histology between high libido (HG) and low libido (L
