Women-specific guide: kisspeptin triggers ovulation, restores menstrual cycles, improves egg quality, and enhances libido. Pulsatile dosing 1-3 mcg/kg or single IVF trigger 6.4 nmol/kg. Results: ovulation day 5-7, cycle restoration 4-6 weeks.
How Kisspeptin Triggers Ovulation
GPR54 activation → GnRH release → pituitary LH surge → ovarian follicle final maturation → ovulation. Pulsatile dosing maintains LH pulsatility mimicking natural patterns. Women experience ovulation within 5-7 days of consistent dosing at therapeutic levels. Predictable, physiologic mechanism.
Menstrual Cycle Restoration
Hypothalamic amenorrhea (lost periods from stress, weight loss, overtraining): kisspeptin reactivates dormant GnRH neurons. Cycles typically restore within 4-6 weeks of consistent pulsatile dosing. Regular 28-day cycles often establish by cycle 2-3. Sustainable without continued treatment after axis re-establishes normal patterns.
Egg Quality and Follicle Development
FSH elevation from kisspeptin drives follicle recruitment and maturation. Egg quality improves through optimized hormonal support. Women experience better ovulation timing, reduced aneuploidy risk, improved fertilization rates. IVF success rates higher with kisspeptin-supported protocols vs standard gonadotropin protocols in some studies.
IVF Trigger Protocol for Egg Retrieval
Single kisspeptin dose 6.4 nmol/kg (3-5 mcg/kg equivalent) administered 34-36 hours before egg retrieval finalizes oocyte meiosis I completion. Replaces or supplements hCG trigger. Results: predictable ovulation timing, high mature egg yields, excellent fertilization. Used successfully in numerous clinics worldwide.
Sexual Function and Libido Enhancement
Estrogen elevation from restored ovulation increases sexual desire, arousal sensitivity, and pleasure responsiveness. Orgasm frequency often increases. Vaginal lubrication improves (critical for sexual comfort). Many women report sexual function returns to pre-amenorrhea levels within 4-8 weeks of treatment.
Fertility Support Beyond Ovulation
Kisspeptin optimizes luteal phase progesterone production critical for implantation and pregnancy maintenance. Women experience extended luteal phase length (often shortened before treatment). Miscarriage risk reduces through improved hormonal support. Pregnancy success rates improve with kisspeptin-optimized cycles vs baseline.
PCOS and Irregular Cycle Management
Polycystic ovary syndrome (PCOS) involves absent/irregular ovulation. Kisspeptin restores GnRH pulsatility, improving LH/FSH ratio and ovulatory function. Women with PCOS experience restoration of regular cycles and fertility through kisspeptin-driven hormonal re-balancing. Particularly effective for insulin-resistant PCOS variants.
Hormonal Balance for General Health
Beyond fertility, optimized estrogen improves bone health, cardiovascular function, skin quality, mood, and metabolic markers. Many women pursue kisspeptin for general health optimization (not just fertility). Sexual function, energy, and mood improvements often secondary benefits beyond reproductive objectives.
Pregnancy and Postpartum Considerations
Once kisspeptin restores ovulation and achieves pregnancy, discontinuation is standard. Pregnancy itself maintains hormonal support. Postpartum: cycles typically resume 6-12 months after lactation cessation. Some women re-use kisspeptin if postpartum amenorrhea develops.

How fast will my periods return?
Menstruation typically resumes 4-6 weeks of consistent dosing. Some women see return within 2-3 weeks; others require 8+ weeks. Individual variation exists based on baseline reproductive dysfunction severity.
Can I use kisspeptin for contraception?
No. Kisspeptin increases fertility—opposite of contraceptive. Requires active pregnancy planning or backup contraception.
Does kisspeptin work for irregular cycles?
Yes. Irregular ovulation (PCOS, stress-induced anovulation) responds well. Kisspeptin restores GnRH pulsatility driving regular monthly cycles.
Will egg quality really improve?
Yes. FSH-driven follicle maturation with optimized LH support improves egg chromosomal quality, fertilization rates, and embryo development potential. IVF success rates higher with kisspeptin support.
How many injections during cycle?
6-8 daily across 12 hours (90-120 min spacing). Continue through full follicular phase leading to ovulation. Most cycles achieve ovulation by day 5-7 of consistent dosing.
Can I use kisspeptin with fertility drugs?
Consult reproductive endocrinologist. Combination protocols possible but require careful monitoring to avoid overstimulation. Some clinics use kisspeptin + gonadotropins for hybrid protocols.
