Yes, you can take birth control while on testosterone. All contraceptive methods are considered safe for people on testosterone therapy, and concurrent use is not a medical contraindication. The more nuanced questions involve which type of birth control fits best with your transition goals, whether testosterone alone prevents pregnancy (it doesn’t reliably), and what side effects to expect.
Testosterone Is Not Birth Control
This is the most important thing to understand: testosterone has never been studied or approved as a contraceptive. While it often stops periods and can suppress ovulation, it doesn’t do so consistently enough to prevent pregnancy. The CDC notes that in one small study tracking ovulation in people on testosterone, 36% of participants showed signs of ovulation when measured with a sensitive threshold. Among those who had been on testosterone longer, the rate dropped to 13%, but among new users it was 100%. That’s far too unreliable to count on.
Unintended pregnancy rates in this population reflect that gap. In a national survey of transgender and nonbinary people assigned female or intersex at birth, 54% of pregnancies were unintended. Eleven percent of respondents who didn’t want to become pregnant still considered themselves at risk. If you have a uterus, engage in sex that could result in pregnancy, and don’t want to be pregnant, you need a separate contraceptive method regardless of your testosterone dose or how long you’ve been on it.
Progestin-Only Methods
Progestin does not interact with testosterone, making progestin-only options the most straightforward choice. These come in several forms: daily pills, a three-month injection, an arm implant, or a hormonal IUD. None of them contain estrogen, which makes them popular among people who want to avoid any hormonal input that feels at odds with their masculinization goals.
The hormonal IUD is one of the most commonly chosen options in gender-diverse populations. In one study at a gender-affirming clinic, 20% of patients used a hormonal IUD for menstrual suppression, and the rate of periods stopping entirely within a year was 89%. The arm implant is another well-tolerated choice. In surveys, many transmasculine individuals preferred condoms and implants specifically because these methods didn’t feel like a daily reminder of their anatomy and weren’t perceived as interfering with testosterone’s effects.
One practical consideration with IUD placement: about half of gender-diverse adolescents in one study opted for sedated placement due to anticipated distress with an office-based procedure. If insertion feels like a barrier, it’s worth asking your provider about comfort options beforehand. Satisfaction rates after placement were high in both transgender and cisgender patients, and complication rates were minimal.
Combined (Estrogen-Containing) Methods
Combined oral contraceptive pills, patches, and rings contain both estrogen and progestin. These are medically safe to use alongside testosterone. However, there are a few reasons many people on testosterone prefer to avoid them.
The estrogen component can cause breast tenderness, which may worsen gender dysphoria, particularly for people who already experience distress related to chest tissue. Taking a daily pill associated with feminizing hormones can also feel psychologically uncomfortable. Some patients have reported a perceived decrease in testosterone’s masculinizing effects while on combined pills, though clinical evidence on whether estrogen actually blunts masculinization at standard contraceptive doses remains unclear.
If a combined method works well for you and doesn’t cause distress, there’s no medical reason to avoid it. But if you have other options that feel more aligned with your goals, progestin-only or non-hormonal methods are equally effective alternatives.
Non-Hormonal Options
Condoms (external or internal) are widely used in this population and have the added benefit of protecting against sexually transmitted infections, something hormonal methods don’t do. Condoms also require no interaction with the healthcare system and carry no hormonal considerations at all.
The copper IUD is another non-hormonal option that provides long-term pregnancy prevention. It won’t help with menstrual suppression (it can actually make periods heavier), so it’s a better fit for people whose primary goal is contraception rather than stopping bleeding. For many people on testosterone whose periods have already stopped, this trade-off may not matter, but it’s worth discussing with a provider.
Menstrual Suppression as a Dual Benefit
For many people on testosterone, stopping periods is just as important as preventing pregnancy. Testosterone alone eventually stops menstruation for most users, but it can take months, and breakthrough bleeding still happens. Adding a hormonal contraceptive method can help close that gap.
In one study of over 500 transgender and gender-diverse young people, about a quarter were already using some form of menstrual suppression when they first visited a gender specialist. The most common methods were combined pills (46.6%), a progestin-only pill (29.8%), and a progestin injection (14.5%). At a single gender-affirming clinic, 70% of patients used a specific progestin pill for menstrual suppression (notably, one that suppresses periods but isn’t technically classified as a contraceptive), while 20% used a hormonal IUD.
If you’re dealing with persistent or breakthrough bleeding on testosterone, a hormonal contraceptive method can serve double duty. The hormonal IUD and progestin-only pills are particularly effective at thinning the uterine lining, which helps stop bleeding and may also offer long-term protection against abnormal endometrial changes. Hormonal contraception containing progesterone is known to protect against endometrial thickening, which may be reassuring for people on long-term testosterone who are not planning a hysterectomy.
Breakthrough Bleeding on Birth Control
Unscheduled spotting or bleeding is the most common side effect of hormonal birth control, and it can happen whether or not you’re on testosterone. With combined pills, breakthrough bleeding is typically worst in the first month and tends to settle within three to four months. If it persists beyond that, switching to a different formulation or adjusting the dose often helps.
For progestin-only methods, irregular bleeding patterns are common in the first several months. The hormonal IUD tends to cause light spotting early on before periods taper off. The injection and implant can cause unpredictable bleeding for some people, though many eventually experience very light or absent periods. If bleeding is a significant source of dysphoria, the hormonal IUD’s high rate of stopping periods entirely (89% at one year) makes it a strong option.
Choosing the Right Method
The best method depends on what matters most to you. If stopping periods is a priority alongside contraception, a hormonal IUD or progestin-only pill offers both. If you want something you don’t have to think about daily, the implant or IUD lasts years. If avoiding hormones entirely is important, the copper IUD or condoms work. If you’re comfortable with estrogen-containing options and they’ve worked well for you, they remain safe on testosterone.
What the clinical guidelines emphasize is simple: all birth control methods should be offered based on individual needs, and testosterone use is not a reason to limit your options. The choice comes down to your contraceptive needs, your comfort with different delivery methods, and how each option fits with your experience of your body.
