- Kisspeptin-54
- GnRH neuron activation
- Restoring ovulatory cycles in hypothalamic amenorrhea
- Strong (RCTs published in JCEM)
- Requires pulsatile administration; no benefit in ovulatory women
- Proven mechanism in specific diagnostic context. Not a general fertility aid
- GnRH Agonists/Antagonists
- Pituitary receptor modulation
- Controlled ovarian stimulation in IVF protocols
- Very strong (standard ART protocol)
- Requires clinical monitoring; suppresses endogenous hormones
- Clinical tool in supervised cycles only. Consumer use unsafe
- Thymosin Alpha-1 / Thymalin
- T-cell modulation, Th1/Th2 balance
- Autoimmune-mediated recurrent pregnancy loss
- Moderate (cohort studies, not RCTs)
- Benefit limited to confirmed autoimmune pathology
- Niche application. Irrelevant without immune diagnosis
- Growth Hormone Secretagogues
- IGF-1 elevation via GH release
- Poor ovarian response in IVF (low IGF-1 phenotype)
- Weak to moderate (mixed trial results)
- Worsens insulin resistance; no benefit in normal responders
- Context-dependent. Harmful if applied broadly
- BPC-157
- Tissue repair signaling (VEGF upregulation)
- Endometrial regeneration research (preclinical)
- Very weak (rodent models only)
- Zero human reproductive data; mechanism unproven in human endometrium
- Speculative. No human evidence supports fertility claims
