Menopause Hormone Therapy (HRT) in Sunnyvale, CA

Bioidentical hormones in Sunnyvale: what it means

"Bioidentical" describes a hormone whose chemical structure matches one the body makes. Estradiol and micronized progesterone are both bioidentical: their structure matches the hormones the ovaries make. FDA-approved versions of both are sold by prescription at retail pharmacies.

Only 14 OB-GYNs list a primary practice address in Sunnyvale in the NPI registry. For 153,455 residents that is 9.1 per 100,000, under the US 17.8 and below California's 16.9. Set against the city's 16,400 women aged 45 to 64, that is one OB-GYN for roughly every 1,170.

Counting the area around it, 524 OB-GYNs practice in Sunnyvale or within 10 miles and 848 within 25 miles: 27.6 for every 100,000 of the 3,077,704 people who live within 25 miles, a dense supply. VevaMD is an online option alongside them: a physician licensed in California reviews your intake from Sunnyvale without an office visit, and an OB-GYN you already see stays your doctor.

"BHRT" often means compounded hormones, a cream, a blend such as Bi-Est or a pellet that a pharmacy mixes for one prescription. They are not FDA-approved, which means the FDA cannot assure their safety or effectiveness. The FDA also says it has no evidence that they are safe and effective, or more effective than approved hormone therapy. A 2020 National Academies review found no rigorous evidence of their safety and effectiveness.

Through VevaMD, a physician licensed in California decides whether hormone therapy fits you and, if so, the form: an estradiol pill, patch, cream or vaginal cream, with progesterone if you have a uterus. Pellets are not part of it. Since the pharmacy that fills these prescriptions also compounds, ask whether yours is an FDA-approved product or compounded. Two options are compounded for certain: testosterone cream for women and Bi-Est are not FDA-approved.

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