NCT06414096

Brief Summary

Hypothesis: The investigators hypothesize that pulsatile FSH intravenous administration to women with obesity will correct the Reprometabolic Syndrome (RMS) luteal deficiency phenotype. Specific Aim: To test the hypothesis that pulsatile IV administration of FSH will rescue the impaired folliculogenesis and relative hypogonadotropic hypogonadism, characteristic of obesity. The investigators will accomplish this by administering a cycle of pulsatile FSH to women with obesity and comparing their hormone output to a cycle using conventional, daily FSH injection at the identical daily dose. The primary outcome will be luteal phase progesterone excretion.

Outcome Measures

Primary Outcomes (1)

  • Urinary Pdg concentration

    The primary endpoint of the study is luteal progesterone metabolite (pregnanediol; Pdg) excretion. Luteal Pdg will be compared in the pulsatile FSH cycle to the daily dose subcutaneous (SQ) cycle. Patients who conceive in the cycle of study will not have their conception cycle included in the analysis.

    4 months

Study Arms (2)

Conventional Subcutaneous FSH Dosing

ACTIVE COMPARATOR

A daily gonadotropin dose (typically 75-450 IU) will be assigned and adjusted, based on clinical criteria and, if known, past response to hormones. Recombinant human FSH (rhFSH) will be given as a daily subcutaneous injection, as is performed, by patients at home, in routine clinical practice.

Drug: Follicle Stimulating Hormone

Pulsatile IV FSH Dosing

EXPERIMENTAL

participants will receive the same daily rhFSH dose (based on clinical practice criteria); however, it will be delivered via a portable infusion pump with reservoir (Avocet Infusion Pump, Eitan Medical LTD) that will provide an IV bolus (100-500 µl) every 90 minutes, a frequency that has previously been shown to result in physiologic ovulatory cycles in GnRH deficient women (Martin). The total gonadotropin dose delivered over a 24 hour period will be typically 75-450 IU, assigned based on standard of care clinical criteria (max dose is 900IU per clinical care guidelines). Participants will be provided with a 100mL preloaded reservoir, calibrated to deliver the approved standard of care dosing, in 16 boluses (100-500µl) over 24 hours (q 90min), for 7-12 days. Each 100 ml reservoir has capacity for 200 doses if the volume is 500 µl, which is sufficient for the typical 7- 12-day protocol.

Drug: Follicle Stimulating Hormone
