The reproductive longevity program,built inside your biology.

Low libido. Vaginal dryness and atrophy. Painful intercourse (dyspareunia). Loss of arousal. Difficulty with orgasm. Post-childbirth tissue changes. Post-menopausal sexual function decline. Reduced sensation. We address these through hormone optimization, regenerative therapies (Vaginal PRP, low-level laser therapy, ozone), microbiome restoration, and individualized clinical protocols. Sexual wellness isn't a bolt-on aesthetic service at RFC — it's measured and treated as a core longevity outcome. Dr. Merhi is one of the few reproductive endocrinologists in the U.S. integrating these therapies into a longevity framework.

Because sexual function is one of the most reliable indicators of how a woman's body is aging — and most longevity programs ignore it entirely. Libido depends on testosterone, estradiol, DHEA, and dopamine signaling. Vaginal tissue health reflects estrogen status, microbiome integrity, and inflammatory burden. Orgasmic function tracks pelvic blood flow and nerve health. We measure all of it because it tells us things blood pressure and ApoB don't. Sexual wellness isn't separate from longevity — it's longevity, in one of its most measurable forms.

Vaginal PRP uses a small sample of your own blood, processed to concentrate the growth factors and platelets, then injected into vaginal and surrounding tissue to stimulate regeneration. Because the material is your own blood, there's no risk of allergic reaction or rejection. The procedure takes under an hour, is performed in-office with local anesthetic, and most patients return to normal activity within 24–48 hours. It's part of the same regenerative platform RFC pioneered for ovarian rejuvenation.

No. RFC Longevity is a private, application-based program. Insurance does not cover preventive longevity care, advanced biomarker panels, or regenerative therapies in the United States. Some specific lab work and prescriptions ordered through the program may be reimbursable through your existing insurance — we provide superbills you can submit. But the program fees themselves are paid out of pocket, like any concierge medical program.

Most patients travel in for the testing visit and physician review, then continue on telehealth from anywhere in the U.S. We have five physical locations across Manhattan, Brooklyn, Westchester, Long Island, and Westport, CT — plus an option for in-person treatment retreats in the Bahamas for select patients in our Deep Dive pathway. Roughly half of our patients fly in once a year for testing and stay local; the other half live in the tri-state area.

Function Health is an algorithm-driven biomarker dashboard with optional generalist physician review. RFC Longevity is a physician-built clinical program where Dr. Merhi — a reproductive endocrinologist with 110+ peer-reviewed publications — personally reviews every panel and builds every protocol. Function Health is a self-serve tool. RFC Longevity is medicine. The other major difference: Function Health doesn't address sexual wellness, regenerative therapies, or reproductive health at any meaningful clinical level. We do.

Most concierge longevity programs were designed by general internists who added hormone testing as an afterthought. RFC Longevity is the inverse — built outward from a reproductive endocrinology foundation. That means we read hormones, fertility markers, sexual function, microbiome, and metabolic signals as one connected system. Other programs price at $20K–$100K per year. We're priced from $2K to $10K. The depth, especially around female-specific biology, is what's different.

Not currently. RFC Longevity is designed specifically around female reproductive, sexual, and hormonal biology — and the medicine, biomarkers, and therapies are calibrated for women. The longevity industry already has many programs built around male physiology; we built this one for the half of the population that's been treated as a footnote.

No. After your testing and physician review, Dr. Merhi builds a written, individualized plan that connects every finding in your panel to a specific therapy or intervention. That can include prescription hormone optimization, IV nutrient protocols, regenerative procedures (where appropriate), microbiome restoration, targeted supplementation, and lifestyle adjustments. The protocol is calibrated to your biomarker pattern. There is no template. Two women in the same age bracket with the same symptoms will often leave with different protocols because their underlying drivers are different.

It's not too late. Perimenopause and menopause are exactly the windows where most women in the U.S. fall through the cracks of standard care — and where the right interventions create the most measurable change. Hormone optimization, sexual wellness restoration (including Vaginal PRP and LLLT for vaginal tissue regeneration), bone health monitoring, and metabolic intervention are most impactful when started in the 40s and 50s. RFC Longevity treats women across the full reproductive arc — fertility through post-menopause — because aging is a continuum, not a stage.
