As a result, research is increasingly focused on exploring the therapeutic potential of targeting the kisspeptin system to treat reproductive disorders. Herein, we investigate the effect of peptidic kisspeptin receptor (KISS1R) agonists (CPD-221 and CPD-77) on gonadotropin release. We conducted in vivo studies to characterize the stimulatory effect of these agonists in comparison with native kisspeptin-10 (Kp10). Further, we investigated their potential use to treat diverse reproductive impairments by using pre-clinical mouse models of hypothalamic amenorrhea and hypogonadotropic hypogonadism (HH). Dose response studies in adult WT male and female mice revealed a powerful stimulatory effect on luteinizing hormone (LH) secretion after the subcutaneous (sc) administration of both compounds. Due to the long-acting effect of CPD-221, its ability to attenuate signaling was studied in a model of hyperstimulated hypothalamic-pituitary-gonadal (HPG) axis, such as one week ovariectomized (OVX) mice, through continuous delivery using Alzet minipumps. One day of treatment was sufficient to significantly attenuate mean LH content. After 7 days of treatment, LH attenuation was evident in mean LH, amplitude of LH pulses and a trend to decrease the number of pulses per hour in comparison to control OVX mice was also observed. Taken together, the pre-clinical data discussed above identify these KISS1R agonists as potential therapeutic tools to activate the reproductive axis in conditions of insufficient GnRH release, i.e. HH and HA, or to decrease axis activity in conditions of excessive activation, with potential applications in PCOS. These agonists represent a novel approach to treat reproductive conditions that significantly affect Women’s Health with high unmet medical needs. Presentation: Sunday, July 13, 2025

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
