Fertility Planning
This protocol is for the PRECONCEPTION window — actively trying to conceive (TTC) or in the preparation runway 3-6 months before TTC starts. It covers BOTH partners: male-factor and female-factor infertility contribute roughly equally to fertility concerns, and the standard pattern of outsourcing all the work to the female partner misses half the relevant biology.
The protocol is structured around a hard pivot: while preconception support is reasonable, the moment pregnancy is CONFIRMED — by a positive home pregnancy test or quantitative beta-hCG — all Phase 2 peptides are off-table without exception. Phase 1 cofactors (B12, plus oral prenatal vitamin) transition to standard prenatal supplementation; the rest of the protocol stops.
This protocol does NOT replace reproductive endocrinologist (REI) or fertility-specialist workup. Standard guidance is: REI evaluation at 12 months of unsuccessful TTC for women under 35, at 6 months for women 35+, immediately for known risk factors (irregular cycles, prior pregnancy losses, suspected male factor, prior pelvic surgery, endometriosis, PCOS, history of cancer treatment). For the male partner: semen analysis is the cornerstone workup and should happen by month 3 of TTC if not already done — it is non-invasive, inexpensive, and frequently identifies issues that change the entire fertility strategy.
It is NOT for users with active or recent (5 years) breast, ovarian, prostate, or other hormone-sensitive cancer history (Phase 2 sex-steroid-axis stimulation is contraindicated); active fertility-treatment cycles (clomiphene, letrozole, gonadotropins, IVF stim) without explicit specialist guidance; or any confirmed pregnancy.
Phases
Phase 1 — Preconception cofactor foundation (both partners)
starting 3-6 months before TTC, throughout TTC, transitions to prenatal at pregnancyStandard preconception guidance for BOTH partners includes folate (via oral prenatal vitamin — 400-800mcg/day for women, 400mcg/day for men, started 3+ months before TTC for neural tube defect prevention and for sperm DNA integrity respectively) and a comprehensive B-vitamin status. B12 1000mcg SubQ weekly addresses B12 deficiency that is common and under-recognized in midlife users; B12 deficiency in either partner can impair fertility (low B12 affects ovulation in women + sperm quality in men) and even mild deficiency during early pregnancy contributes to neural-tube-defect risk. This phase continues through TTC and converts to standard prenatal supplementation on confirmed pregnancy. Important: this protocol does NOT include folate in the peptide stack because folate is not a peptide and is best taken via oral prenatal vitamin (better controlled dose, dietary integration, lower cost). Standard preconception supplementation includes folate 400-800mcg/day from an OTC prenatal vitamin starting at least 3 months before TTC; do not skip it.
- B12 (Methylcobalamin)1 mg · once weekly · morning
1000mcg SubQ once weekly. Methylcobalamin is the bioavailable form (some users have functional MTHFR variants that slow conversion of cyanocobalamin). Continues throughout TTC; on confirmed pregnancy, transition to prenatal vitamin B12 unless a clinician advises continued supplementation for documented deficiency.
What “working” looks like
Energy + cognitive baseline supported. No specific fertility-outcome change expected from Phase 1 alone — this is the foundational nutrition layer that good preconception care includes regardless of any peptide adjuncts. The cleanest read is at 3-6 months of consistent Phase 1 + REI / urology workups done: you've established the foundation AND identified any specific factors that warrant Phase 2 specialist-guided peptide adjuncts.
Decision criteria
Phase 1 continues throughout TTC. Decisions about Phase 2 should be made WITH a fertility specialist — REI for women, urologist or REI for men. If TTC has been unsuccessful for 6 months (women 35+) or 12 months (women <35) and basic workups suggest a specific issue (cycle irregularities, low ovarian reserve, suspected male factor with abnormal semen analysis), specialist consultation is high-leverage. Phase 2 peptides should not be self-determined.
Labs to pull
- Female partner: AMH (anti-Müllerian hormone — ovarian reserve), FSH + estradiol day 3 of cycle, antral follicle count on transvaginal ultrasound, TSH + free T4 + TPO antibodies, prolactin, vitamin D, ferritin + CBC, B12 + RBC folate, A1c
- Male partner: semen analysis (volume, count, motility, morphology) — repeat at least once if abnormal, ideally with a fertility-specialist-affiliated lab; total + free testosterone, FSH, LH, prolactin, vitamin D, ferritin, B12, A1c
- Both partners: cycle tracking (ovulation prediction kits, basal body temperature, fertility app), preconception genetic carrier screening (cystic fibrosis, spinal muscular atrophy, fragile X, expanded panels per clinician guidance)
Phase 2 — Specialist-guided adjuncts (kisspeptin for women / CJC-Ipa for men preparation)
weeks 12+, ONLY under fertility specialist guidanceOPTIONAL AND SPECIALIST-GUIDED. This phase splits by partner-specific context and should never be self-determined: For the FEMALE partner with cycle irregularities (hypothalamic amenorrhea, hypothalamic-axis dysfunction, low-amplitude LH pulses on workup), kisspeptin has Tier 2 evidence in research-clinical contexts for restoring LH pulsatility and menstrual cyclicity (Imperial College / Dhillo lab; Jayasena 2014 and follow-ups). Community single-daily SubQ dosing is extrapolation from research pulsatile protocols (~6.4-12.8mcg per pulse every 90 minutes); for fertility-planning specifically, REI involvement is non-negotiable — they may use kisspeptin as part of structured fertility-treatment cycles where the dosing follows research-protocol patterns rather than community simplifications. For the MALE partner in the PREPARATION WINDOW (3-6 months before active TTC starts), CJC-1295 / Ipamorelin may support body composition and recovery. HOWEVER: there is no published data on GH-axis stimulation effects on semen quality or epigenetic effects during spermatogenesis (~74-day spermatogenic cycle). Conservative practice is to DISCONTINUE CJC/Ipa at least 8-12 weeks BEFORE active TTC starts, allowing a full spermatogenic cycle in the absence of any GH-secretagogue exposure. Continued use during active TTC is NOT recommended without explicit urologist or REI input. Continue Phase 1 B12 + oral prenatal throughout.
- B12 (Methylcobalamin)1 mg · once weekly · morning
Continue Phase 1 cofactor.
- Kisspeptin100 mcg · once daily · morning (community extrapolation; REI may prescribe pulsatile)
FEMALE PARTNER ONLY, under REI guidance. 100mcg SubQ once daily is community extrapolation; REI-managed protocols may follow research pulsatile patterns (~6.4-12.8mcg per pulse every 90 minutes) instead. The strongest evidence-base indications are hypothalamic amenorrhea (restoring cyclicity) and IVF oocyte maturation triggering — both REI-managed. Self-determined community use for 'fertility support' without confirmed cycle dysfunction lacks evidence.
- CJC-1295 / Ipamorelin250 mcg · 5 days per week (preparation window ONLY) · before bed, fasted 2+ hours
MALE PARTNER, PREPARATION WINDOW ONLY (3-6 months before TTC starts). Discontinue 8-12 weeks BEFORE active TTC begins to allow a full spermatogenic cycle without GH-secretagogue exposure. 10 units SubQ (250mcg CJC + 250mcg Ipa) 5 days/week, before bed, fasted 2+ hours. NOT for use during active TTC without explicit urologist/REI input — no published data on semen quality or epigenetic effects during spermatogenesis.
What “working” looks like
For the female partner: kisspeptin-responsive cycle dysfunction shows LH pulsatility restoration (specialist-monitored), cycle regularization, and improved odds of conception in subsequent cycles. For the male partner: kisspeptin and CJC/Ipa are not expected to improve semen analysis values in users with baseline-normal semen analyses; for users with documented low T + secondary hypogonadism, the Andropause protocol's Phase 2 kisspeptin layer may be more appropriate than fertility-specific use. NO direct fertility-outcome data exists for any of these peptide adjuncts in unselected eugonadal users — the strongest evidence is in specific reproductive endocrinology contexts where the specialist drives the protocol.
Decision criteria
Phase 2 is specialist-managed. Decisions about continuation, dose adjustment, or discontinuation belong with the REI or urologist, not with this protocol. On confirmed pregnancy (positive home test or quantitative beta-hCG): STOP all Phase 2 peptides immediately without exception. Phase 1 cofactors transition to standard prenatal supplementation per OB-GYN guidance.
Cautions
- CONFIRMED PREGNANCY IS A HARD STOP for the entire Phase 2 stack. The moment pregnancy is confirmed — positive home pregnancy test, quantitative beta-hCG, or clinical confirmation — Phase 2 peptides stop immediately without exception. Kisspeptin and CJC/Ipa have no human pregnancy safety data and should not be continued. Phase 1 cofactors continue (B12 is standard prenatal supplementation) under OB-GYN guidance.
- Active or recent (within 5 years) breast, ovarian, prostate, endometrial, or other hormone-sensitive cancer history is a HARD EXCLUSION for Phase 2. Sex-steroid-axis stimulation (kisspeptin) and GH-axis stimulation (CJC/Ipa) are contraindicated. Fertility planning after cancer treatment is a specialist-managed pathway — REI + oncology coordination — not a community protocol.
- Active fertility-treatment cycles (clomiphene, letrozole, gonadotropins, GnRH agonists/antagonists, IVF stimulation) are managed by your REI — adding kisspeptin without their explicit guidance can interact with the structured protocol they're running and is dangerous. Defer to your REI for ALL fertility-treatment-related peptide decisions.
- Female age 35+ with 6+ months of unsuccessful TTC: REI workup is higher leverage than peptide adjuncts. Age-related ovarian reserve decline is the dominant factor for many users in this cohort, and time matters — every cycle waited reduces success rates. Do NOT use this protocol as a reason to delay REI evaluation.
- Male semen analysis is the cornerstone of male fertility workup and should happen by month 3 of TTC if not already done. Abnormal semen analysis (low count, low motility, abnormal morphology) often warrants urology referral and may not be addressed by either peptide adjunct in this protocol; varicocele repair, lifestyle modification, antioxidant supplementation, or assisted reproduction techniques may be the actual indicated interventions.
- Male partners using CJC/Ipa during the active TTC window are operating without any published data on semen quality or epigenetic effects during spermatogenesis. Conservative practice is the 8-12 week washout before TTC starts; continued use during active TTC requires urologist or REI input — do not self-determine this decision.
- Preconception genetic carrier screening (cystic fibrosis, spinal muscular atrophy, fragile X, hemoglobinopathies, expanded panels) is recommended for BOTH partners regardless of peptide use. ACOG and ACMG guidance is to discuss with a clinician. This protocol does not address genetic factors that may significantly change fertility planning.
- Pediatric exclusion. This protocol is for adults 18+ in preconception planning.
Discuss with your clinician
- Before starting: have a preconception visit with your primary care or OB-GYN. The visit covers: review of medical history + medications (some teratogenic medications need to be discontinued or transitioned BEFORE TTC), vaccinations (rubella, varicella, hepatitis B status), preconception genetic carrier screening discussion, folate supplementation (start 3+ months before TTC), and timing of when to seek REI consultation.
- Female partner Phase 1 workup with OB-GYN or REI: AMH, day 3 FSH + estradiol, antral follicle count on TVUS, TSH + free T4 + TPO antibodies, prolactin, vitamin D, ferritin, B12 + RBC folate, A1c. AMH below the age-adjusted threshold may significantly change the fertility-planning timeline.
- Male partner Phase 1 workup: semen analysis (volume, count, motility, morphology) — this is non-invasive, inexpensive, and frequently identifies actionable issues. Total + free T, FSH, LH, prolactin, vitamin D, ferritin, B12. If semen analysis is abnormal, urology referral.
- If pursuing Phase 2 (kisspeptin for cycle irregularities): the specialist-managed REI pathway is the appropriate route — they may use kisspeptin within structured fertility-treatment cycles where research-protocol pulsatile dosing applies. Community single-daily SubQ dosing for vague 'fertility support' lacks evidence.
- If pursuing Phase 2 (CJC/Ipa for male preparation window): coordinate with urologist or REI. Confirm the 8-12 week washout window before active TTC begins. Do not continue during active TTC without explicit specialist input.
- On confirmed pregnancy: contact OB-GYN immediately for prenatal care transition. STOP Phase 2 peptides. Continue Phase 1 cofactors per OB-GYN guidance (typically transitioned into a standard prenatal vitamin program).
Evidence summary
Tier 3 protocol overall. Phase 1 (B12 cofactor with folate-via-prenatal framing) is Tier 1-2: folate for neural tube defect prevention is among the most evidence-based preconception interventions in modern medicine (Tier 1); B12 for confirmed deficiency is Tier 2. Phase 2 splits significantly by indication: kisspeptin is Tier 2 for hypothalamic amenorrhea + IVF oocyte maturation triggering in REI-managed research-clinical contexts (Imperial College / Dhillo lab; Jayasena 2014, Abbara 2015), but Tier 3 for community single-daily SubQ dosing extrapolated from those pulsatile protocols. CJC/Ipa is Tier 2 for GH/IGF-1 axis restoration on component PK/PD data; Tier 3-4 for use in male preconception specifically — no published data on semen quality or epigenetic effects during spermatogenesis. Honest framing: the strongest evidence for any peptide in this protocol is in REI-managed contexts; community self-determined use lacks comparable evidence and the protocol surface should not appear to substitute for specialist input.

- KisspeptinKISS1R agonist (hypothalamic neuropeptide)
- CJC-1295 / IpamorelinBlend
Often combined with
- Postpartum Recovery
Postpartum users may re-enter fertility planning after weaning (typically 6-12 months postpartum minimum; longer is reasonable). The lab workup baseline often differs from a first-pregnancy preconception workup — ferritin and thyroid status may need re-establishment after the postpartum window. Coordinate transition with OB-GYN.
- Energy & Vitality
B12 + B-vitamin overlap with Energy Phase 1. If you're running both protocols (e.g., addressing fatigue alongside preconception planning), do NOT double-dose B12 — single weekly dose covers both surfaces. Energy protocol's broader cofactor work may also benefit preconception nutrient status.
