SOURCE-LINKED STUDY SUMMARY
Repeated systemic β-NGF administration improves ejaculate characteristics in rams.
Abstract summarized · Quality not appraised
- Studied
- An experiment tested whether repeated beta-nerve growth factor administration changed semen characteristics in rams.
- Who / model
- Adult Corriedale rams received four administrations five days apart or remained untreated, with nine animals per group. Semen was collected before treatment through day 58.
- Studied dose & schedule
- Dose and schedule have not yet been extracted for this summary.
- Found
- Total sperm per ejaculate increased at selected time points, and volume increased on day 37. Sperm motility, shape, membrane function, testosterone and scrotal circumference showed no detectable treatment changes.
- Limits
- The response was temporary. Effects on fertility and semen preservation, and the underlying mechanism, remain uncertain.
