01 / DESIGN
What was studied?
Ewe lambs were repeatedly sampled across development to compare circulating neuropeptides with the timing of first ovulation.
02 / FINDINGS
What did the researchers report?
Kisspeptin-10 and neurokinin B rose with age, while dynorphin-related patterns moved in the opposite direction across the studied groups.
03 / LIMITS
How should it be interpreted?
These are developmental associations rather than a treatment experiment. Pregnancy grouping, age and species-specific physiology limit causal and human interpretation.
