Menopause Hormone Therapy (HRT) in Mountain View, CA

Bioidentical hormones in Mountain View: what it means

Behind the label "bioidentical hormone replacement therapy" is a plain idea: a hormone whose structure matches the body's own. Estradiol and micronized progesterone are both bioidentical: their structure matches the hormones the ovaries make. Neither has to be compounded: FDA-approved estradiol comes as pills, patches, gels, sprays, vaginal creams and rings, and progesterone as capsules.

Compounded hormones are a different thing: a pharmacy prepares them for one patient, as a cream, a capsule or a pellet. Compounded drugs are not FDA-approved, so the FDA cannot assure their safety, effectiveness or dose. In the FDA's words, it has no evidence that compounded "bioidentical hormones" are safe and effective. When the National Academies reviewed them in 2020, the evidence was mostly low quality, such as anecdotes and patient reports.

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. Because the dispensing pharmacy also compounds, you can ask whether your estradiol or progesterone is an FDA-approved product. Two options are compounded for certain: testosterone cream for women and Bi-Est are not FDA-approved.

The NPI registry counts 72 OB-GYNs practicing in Mountain View, about 87.4 for every 100,000 residents against 17.8 nationally and above California's 16.9, a higher rate than 95% of the cities VevaMD covers. With about 9,417 women aged 45 to 64 living in Mountain View, that is about 130 for each OB-GYN in the city, before counting any younger patients.

Counting the area around it, 507 OB-GYNs practice in Mountain View or within 10 miles and 828 within 25 miles: 25.8 for every 100,000 of the 3,212,358 people who live within 25 miles, a dense supply. None of this replaces your own OB-GYN or a menopause doctor you trust; VevaMD adds an online route, with a physician licensed in California reviewing your answers from home in Mountain View.

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 recommends FDA-approved menopause hormone therapy over compounded hormones.
