Menopause Hormone Therapy (HRT) in Rancho Cucamonga, CA

Bioidentical hormones in Rancho Cucamonga: what it means

If you are one of the 23,999 women aged 45 to 64 in Rancho Cucamonga and have searched for "bioidentical" hormones: the word means a hormone whose structure matches one the body makes. Estradiol, the main estrogen the ovaries make before menopause, and micronized progesterone both fit that description. Both come in FDA-approved prescription forms, from estradiol pills, patches, gels and vaginal forms to progesterone capsules.

Rancho Cucamonga has fewer OB-GYNs per resident than the country: the federal NPI registry lists 4 with a primary practice address in the city, 2.3 per 100,000 residents against 17.8 nationally and below California's 16.9. With about 23,999 women aged 45 to 64 living in Rancho Cucamonga, that is about 6,000 for each OB-GYN in the city, before counting any younger patients.

Even counting 25 miles out, there are 465 OB-GYNs (81 within 10 miles) for 3,757,524 residents: 12.4 per 100,000, below the national rate. VevaMD is an online option alongside them: a physician licensed in California reviews your intake from Rancho Cucamonga without an office visit, and an OB-GYN you already see stays your doctor.

Compounded hormones are a different thing: a pharmacy prepares them for one patient, as a cream, a capsule or a pellet. None of these is FDA-approved, and the FDA has not reviewed them for safety, effectiveness or quality before sale. The FDA says it has no evidence that compounded "bioidentical hormones" are safe and effective, or more effective than FDA-approved hormone therapy. When the National Academies reviewed them in 2020, the evidence was mostly low quality, such as anecdotes and patient reports.

You do not choose a "bioidentical" product from a menu: after a private intake, a physician licensed in California decides what, if anything, fits, and the form. Pellets are not part of it. The pharmacy that fills VevaMD prescriptions also compounds, so ask your physician whether yours is an FDA-approved product or compounded. Testosterone cream for women and Bi-Est are compounded and not FDA-approved.

Then there are pellets, implanted under the skin at a clinic; compounded pellets are not FDA-approved. The Endocrine Society cites blood levels well above the expected range in women using compounded pellets. ACOG advises FDA-approved hormone therapy over compounded preparations.
