- Thymalin
- Thymic immune modulation. Restores T-regulatory cell function to reduce ovarian inflammation
- Immune rebalancing in follicular microenvironment
- 5–10mg/week subcutaneous
- Injection (reconstituted)
- Preclinical models; human autoimmune data
- Strongest evidence for immune-driven egg quality issues (unexplained infertility, autoimmune history)
- MK-677
- Ghrelin mimetic. Stimulates endogenous GH pulses to increase IGF-1 signaling in granulosa cells
- GH-IGF-1 axis optimization
- 12.5–25mg/day oral
- Capsule or liquid suspension
- IVF adjunct trials (rhGH analog); Phase 2 completed
- Best option for women with low ovarian reserve or poor IVF response history
- Dihexa
- BDNF upregulation. Enhances mitochondrial biogenesis and reduces oxidative stress in oocytes
- Neurotrophic factor signaling (TrkB receptor pathway)
- 1–5mg/week intranasal or subQ
- Nasal spray or injection
- Cognitive studies; reproductive application theoretical
- Most speculative but addresses mitochondrial root cause directly
- Cerebrolysin
- Neurotrophic peptide blend. Supports cellular repair and reduces apoptosis markers
- Multi-pathway neuroprotection (parallels BDNF, NGF)
- 5–10mL IV or IM per session
- Injection (pre-mixed solution)
- Neurological indications; no fertility-specific trials
- Limited data in reproductive contexts; mechanistically plausible
