Women using testosterone gel should apply it to the lower abdomen, outer thighs, or buttocks. These are the recommended sites because they offer good absorption through the skin while being easy to cover with clothing, which helps prevent accidental transfer to other people.
Recommended Application Sites
The three primary areas for women are the lower abdomen, the outer thighs, and the buttocks. Apply the gel to clean, dry skin and let it air-dry before getting dressed. You should rotate between these sites rather than using the same spot every day. Rotating helps maintain skin health and may modestly improve how much testosterone your body absorbs. One pharmacokinetic study found that spreading application across multiple skin areas increased absorption by about 23% compared to applying to the same single site repeatedly.
The gel typically dries in under five minutes and leaves no visible residue. Once dry, cover the area with clothing. This is especially important if you have physical contact with a partner, child, or pet, since testosterone can transfer through skin-to-skin touch. Research on transdermal transfer showed that when the application site was covered by a T-shirt during physical contact, testosterone levels in the untreated partner did not rise above baseline.
Why Application Site Matters for Women
Testosterone gel can cause increased hair growth at the exact spot where it’s applied. This is a well-documented localized side effect. In clinical studies of transdermal testosterone in women, the most common side effect was dose-related hair growth, predominantly at the delivery site. One case report even documented a woman who developed thick hair growth on her forearm simply from accidental contact with her husband’s testosterone gel.
This is a practical reason to avoid applying the gel to your forearms, chest, or anywhere that localized hair growth would be especially noticeable or unwelcome. Sticking to the lower abdomen, outer thighs, or buttocks keeps the application area discreet and easy to monitor.
Dosing Is Much Lower Than for Men
Women use roughly one-tenth of a standard male dose. Clinical studies for female use targeted about 5 mg of testosterone daily, compared to the 50 mg contained in a typical male dose tube. If you’re using a 1% testosterone gel packaged for men (which is common, since no female-specific product is widely available in many countries), the starting dose is about 0.5 mL of the tube’s contents. Your prescriber may increase this to 1 mL (10 mg) if needed.
This off-label use of male formulations is considered reasonable under international guidelines, as long as blood levels stay within the normal premenopausal female range. The 2019 global consensus statement on testosterone therapy for women was clear that doses resulting in above-normal testosterone levels are not recommended, as they carry risks of acne, scalp hair thinning, weight gain, and other masculinizing effects.
After Application: Showering and Exercise
Wait at least two hours before showering, swimming, or bathing. Water can wash away the gel before your skin has fully absorbed it. Heavy sweating from exercise could have a similar effect, so morning exercisers may want to apply the gel afterward rather than before a workout. If you apply it at bedtime, the gel has plenty of uninterrupted time to absorb overnight, though wearing pajamas that cover the site is important if you share a bed.
Preventing Transfer to Others
Accidental testosterone exposure is a real concern, particularly for children. After applying the gel, wash your hands thoroughly with soap and water. Cover the application site with clothing once the gel is dry. Avoid skin-to-skin contact at the application area for at least two hours. If someone does accidentally touch the area before it’s covered, they should wash the exposed skin right away with soap and water.
Blood Tests and Monitoring
You’ll typically have a blood test for total testosterone before starting treatment, then again at three to six weeks to confirm your levels are in the right range. For transdermal gel, the blood draw is most informative when done two to eight hours after your most recent application, after you’ve been using the gel consistently for at least a week. This captures your peak absorption window and gives your prescriber the clearest picture of whether the dose needs adjusting.
If you don’t notice any benefit after six months of use, the global consensus recommendation is to stop treatment. Testosterone gel for women is currently supported by evidence only for low sexual desire (hypoactive sexual desire disorder) in postmenopausal women, and not every woman responds. Continuing indefinitely without improvement offers no known advantage and adds unnecessary hormone exposure.
