SOURCE-LINKED STUDY SUMMARY
In vivo evidence for Urotensin II as a regulator of reproduction in GIFT tilapia (Oreochromis niloticus).
Abstract summarizedQuality not appraised
- What was studied
- How the peptide urotensin II regulates reproductive signaling and gonadal development in tilapia.
- Who / model studied
- Farmed tilapia studied with acute injections, receptor blockade using urantide and sustained-release delivery. Sample sizes and the sustained-treatment duration are not stated in the abstract.
- Studied dose & schedule
- Dose and schedule were not reported in the source used for this summary.
- What the study found
- Urotensin II increased reproductive gene activity, with acute effects blocked by urantide. Sustained delivery increased estradiol in females and testosterone in males, alongside faster sperm development and egg maturation.
- Limitations & context
- This is fish reproductive biology research. It does not demonstrate a human hormone-enhancement benefit.
