Hormone Therapy Guide · Vyta MenoClinic
The truth about
hormone therapy.
Hormone replacement therapy has been misunderstood, misrepresented, and withheld from millions of women who could benefit. This guide gives you the real evidence — so you can make an informed decision with your physician.
The History
Why women were told to
fear their hormones.
In 2002, the Women's Health Initiative (WHI) published a study claiming HRT increased breast cancer risk. Overnight, prescriptions plummeted — and millions of women were left to suffer without treatment.
The study had serious flaws: it used synthetic progestins (not bioidentical progesterone), enrolled women who were significantly older and sicker than typical HRT candidates, and misrepresented statistical risk.
The science has since been substantially revised. Every major menopause society — including The Menopause Society (NAMS) — now states that HRT is safe and effective for most healthy women under 60.
What We Know Now
- ✓ HRT significantly reduces hot flashes and night sweats
- ✓ Protects bone density and reduces fracture risk
- ✓ Transdermal estrogen does not increase clot risk
- ✓ Bioidentical progesterone does not increase breast cancer risk
- ✓ HRT started within 10 years of menopause may reduce cardiovascular risk
- ✓ Cognitive protection is greatest when HRT is started early
Myth vs. Reality
5 HRT myths,
corrected by evidence.
Myth
HRT causes breast cancer
Evidence
The risk was vastly overstated by a 2002 WHI study now known to have significant methodological flaws. Most women starting HRT at menopause do not have increased breast cancer risk — and many have reduced risk when started in the "window of opportunity."
Myth
HRT should only be used short-term
Evidence
There is no medical mandate for a time limit on HRT. The "5-year rule" was an artifact of outdated guidelines. Current evidence supports continued use as long as benefits outweigh risks — which for most healthy women, they do.
Myth
All hormones are the same
Evidence
Synthetic progestins (used in older HRT formulas) are not equivalent to bioidentical progesterone. The type, route, dose, and timing of hormones matter enormously — which is why Vyta individualizes every protocol.
Myth
If your symptoms aren't severe, you don't need HRT
Evidence
Hormone therapy has benefits beyond symptom relief: bone protection, cardiovascular benefit when started early, cognitive protection, and long-term metabolic health. You don't need to be suffering to benefit.
Myth
You can't start HRT after 60
Evidence
While the "timing hypothesis" suggests early start is optimal, HRT can be considered at any age with proper physician evaluation. The risk-benefit equation changes with age — but it doesn't automatically tip against HRT.
Types of
hormone therapy.
Estrogen Therapy
For women without a uterus
Delivery Routes
- · Oral tablets
- · Transdermal patches
- · Gels & sprays
- · Vaginal rings
Best for: Post-hysterectomy women or those needing flexible dosing options.
Combined Estrogen + Progesterone
For women with a uterus
Delivery Routes
- · Oral combination
- · Sequential patches
- · Bioidentical progesterone capsules
- · Mirena IUD (local progestin)
Best for: Women with an intact uterus — progesterone protects the uterine lining.
Bioidentical HRT
Molecularly identical to human hormones
Delivery Routes
- · Compounded creams & gels
- · FDA-approved BHRT (Prometrium, Bijuva)
- · Pellets (with caveats)
- · Troches
Best for: Women who want hormones that match their body's own molecular structure.
Testosterone Therapy
Often overlooked in women
Delivery Routes
- · Compounded topical cream/gel
- · Subcutaneous pellets
- · Anastrozole (if needed)
Best for: Women with low libido, energy issues, muscle loss, or mood symptoms alongside estrogen therapy.
Local / Vaginal Estrogen
Minimal systemic absorption
Delivery Routes
- · Vaginal cream (Estrace)
- · Vaginal ring (Estring)
- · Suppositories (Vagifem)
- · Ospemifene (oral SERM)
Best for: Women with GSM symptoms only, or those who prefer to avoid systemic hormones.

Month 1–2
Energy & Mood
Most women notice sustained energy improvements, reduced brain fog, and emotional stability.
Month 2–3
Libido & Skin
Sexual health improvements and skin texture changes become noticeable, especially with testosterone.
