Could a natural hormone restore ovulation in women with hypothalamic amenorrhea?
NCT ID NCT05633966
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early study tested whether a naturally occurring hormone called kisspeptin can stimulate reproductive hormones and help women with hypothalamic amenorrhea (a condition where periods stop due to low hormone levels) release eggs. Thirteen women received pulsatile injections of kisspeptin under the skin for two weeks. Researchers monitored egg development with ultrasound and measured hormone levels through frequent blood draws to see if the treatment could trigger ovulation.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- kisspeptin (a naturally occurring hormone)
- What this could lead to
- If it works, this could point toward a new treatment for women with hypothalamic amenorrhea to help them ovulate without traditional hormone therapies.
- What could go wrong
- This is a very small, early Phase 1 trial with only 13 participants. It is designed to test safety and basic effects, not to prove effectiveness. The results may not apply to all women with reproductive disorders.

Inclusion Criteria: * Acquired hypogonadotropic hypogonadism (hypothalamic amenorrhea, aka functional hypothalamic amenorrhea) • Confirmed diagnosis by medical provider supported by low sex steroids in the setting of low or inappropriately normal gonadotropins\] * Normal blood pressure (systolic BP \< 140 mm Hg, diastolic \< 90 mm Hg) * Laboratory Studies: * Hemoglobin no less than 0.5 g/dL below the lower limit of the reference range for normal women * Negative serum hCG pregnancy test at screening (additional urine pregnancy test will be conducted prior to drug administration) * No current or recent use of a medication that, in the opinion of a study investigator, can modulate the reproductive axis or willing to complete an appropriate washout for that particular medication and method of administration Exclusion Criteria: * Any condition (medical, mental, or behavioral) that, in the opinion of a study investigator, would likely interfere with participation in/completion of the protocol * Excessive alcohol consumption (\>10 drinks/week) and/or active use of illicit drugs • Any active use of marijuana will be evaluated by a study medical professional to determine if it may impact study participation. * Pregnant or trying to become pregnant * Breast feeding * History of: bilateral oophorectomy (both ovaries were removed), breast cancer, thromboembolic disease, coronary artery disease, stroke, thrombophilic disorders, or undiagnosed abnormal genital bleeding
