What Is Progynova?

Progynova is Bayer AG’s brand of estradiol valerate — an ester of 17β-estradiol, the primary human oestrogen. After oral ingestion, it is rapidly hydrolysed to estradiol, making it bioequivalent to natural oestrogen. It is the most widely prescribed oral oestrogen in Europe and one of the oldest (in use since 1954).

What Is Progynova Used For?

• Menopausal HRT — relieving hot flushes, night sweats, vaginal dryness, mood changes, and sleep disturbance associated with oestrogen deficiency at menopause
• Surgical menopause — oestrogen replacement after oophorectomy (ovary removal)
• Gender-affirming HRT (trans women) — feminising hormone therapy; increases breast development, redistributes fat to hips/thighs, softens skin, reduces body hair growth
• Hypogonadism — primary oestrogen deficiency in young women (Turner syndrome, premature ovarian insufficiency)
• Osteoporosis prevention — oestrogen preserves bone density at menopause

Progynova Dosage Guide

Progynova for Trans Women: Complete HRT Context

For gender-affirming HRT, Progynova is typically one component of a two-part regimen:

1. Oestrogen (Progynova / estradiol) — feminises body composition, skin, hair, and promotes breast development
2. Anti-androgen — suppresses testosterone to below female-typical range. Common options available at MedsBase include cyproterone acetate (contained in Diane-35 at 2mg; standalone cyproterone at higher doses for HRT is unavailable at MedsBase currently) or spironolactone

Many trans women self-managing HRT follow monitoring guidelines from informed consent clinics and the WPATH Standards of Care. Regular oestradiol and testosterone blood tests guide dose adjustments — these are available from private labs without a GP referral in most countries.

Side Effects of Progynova

• Common (5–10%): Nausea (take with food), breast tenderness, bloating, headaches, mood changes — usually settle after 1–2 months
• VTE risk: Oral oestrogens carry a small increased risk of blood clots vs no HRT. Risk is lower with transdermal oestrogen (patches, gel). For most healthy women under 60, absolute risk remains low. Smoking significantly multiplies this risk.
• Not associated with: Liver damage at standard doses; breast cancer risk at under 5 years use is not statistically significant in most studies

Progynova vs Patches vs Gel: Which Oestrogen Route Is Best?

Oral tablets (Progynova) are convenient but have higher first-pass metabolism, leading to elevated clotting factors compared to transdermal routes. For women over 60 or with VTE risk factors, transdermal oestrogen is preferred. For most healthy women under 60, oral Progynova is safe and highly effective.

For trans women optimising estradiol levels on a budget, sublingual Progynova achieves near-transdermal bioavailability without the cost of patches.

Frequently Asked Questions

Is Progynova the same as estradiol?

Progynova contains estradiol valerate, which is rapidly converted to 17β-estradiol in the body. For practical purposes it is estradiol — the same hormone your body produces naturally. The “valerate” ester simply improves oral bioavailability.

Can I buy Progynova without a prescription?

At MedsBase, yes. In the UK and EU, Progynova requires a prescription. MedsBase is an international pharmacy that can dispense without a local prescription. You should still monitor your hormone levels with blood tests and adjust dose accordingly.

How long does it take for Progynova to work for menopause symptoms?

Hot flushes and night sweats typically improve within 2–4 weeks. Sleep quality and mood often improve alongside vasomotor symptoms. Vaginal dryness may take 8–12 weeks to fully resolve. Full benefit on bone density requires 1–2 years of consistent HRT.

How long does Progynova take to work for breast development (trans HRT)?

Breast budding typically begins within 2–6 months of starting oestrogen. Full breast development takes 2–5 years and is strongly influenced by genetics. Achieving and maintaining estradiol in the 100–200 pg/mL range gives the best growth potential.

Does Progynova cause weight gain?

HRT generally does not cause weight gain. Fat redistribution occurs — particularly in trans women, where fat shifts from abdomen to hips and thighs — but this is a change in distribution, not an increase in total weight. Menopausal women who gain weight during HRT would typically gain more weight without it, as menopause itself changes metabolism.

Can I take Progynova if I still have a uterus?

Oestrogen-only HRT (Progynova alone) in women with an intact uterus increases endometrial cancer risk. Always combine with a progestogen (e.g. micronised progesterone / Utrogestan, or a combined pill like Kliogest). Trans women do not have a uterus and use oestrogen-only without this concern.
