External testosterone and anabolic steroids can affect sperm production; the effect varies from person to person.

What can change with external testosterone

Testosterone produced by the body plays a role in reproductive function. Testosterone given from outside the body—for example, as treatment—can reduce the hormonal signals that stimulate production in the testicles. In some people, this decreases sperm production and may affect fertility. Anabolic steroids can also alter hormonal balance and sperm production.

The effects vary from person to person

The response depends on individual factors, the substance, and the context in which it is used. Sperm count can decrease substantially, although the effect is not the same for everyone. If the substance is stopped, recovery is not guaranteed and does not follow a set timeline. Therefore, do not assume that fertility will be fully restored or restored by a particular date.

Fertility problems do not always cause visible signs

A change in sperm production may not cause noticeable changes. Having no symptoms does not confirm that fertility is unaffected; physical or sexual changes also cannot, on their own, identify the cause. When appropriate, an evaluation is based on medical history and tests selected by health care professionals.

Discuss your reproductive plans before starting

If you want to conceive now or may want children in the future, tell the health care professional who recommends or supervises your treatment before starting or changing it. This allows you to consider your reproductive goals alongside the reason for treatment and assess whether tests or other options may be appropriate. If you are already using testosterone or anabolic steroids, explain what you have used and for how long. Do not adjust or stop treatment on your own.

What an evaluation may include

Depending on a person's medical history and circumstances, the health care professional may consider a semen analysis, a hormone evaluation, or other steps. Not everyone needs the same tests; selecting and interpreting them requires clinical context. Depending on the case, endocrinology, urology, or andrology professionals may be involved.

If you are already trying to conceive

If you are having difficulty achieving a pregnancy, seek an evaluation rather than automatically attributing it to hormone use. Fertility can depend on different factors in any of the people involved. Tell your health care team about any hormone treatment or anabolic steroid use so they can guide you on next steps.

What to avoid

Do not stop prescribed testosterone without speaking with the person who prescribed it, and do not use medications or supplements to try to restore fertility without supervision. A product advertised as “natural” may also have effects; do not assume that a particular dose or formulation has no reproductive risks. Base decisions on an individual assessment, not on social media advice or other people's experiences.

Plan with information

External testosterone and anabolic steroids can affect sperm production, but the effects and how they change over time vary. If you are interested in having children now or in the future, discuss your plans before starting or changing treatment. This content is educational and does not replace a medical consultation.

When to seek medical care

If symptoms persist, test results are abnormal, or you have questions about medication, arrange an individual assessment. Do not change treatment or doses without medical guidance.

Frequently asked questions

Can prescribed testosterone also affect fertility?

Yes. Testosterone given from outside the body can reduce sperm production, even when prescribed as treatment. Discuss your reproductive plans with the health care professional supervising your treatment before starting or changing it.

Does fertility always return after stopping testosterone or anabolic steroids?

Complete recovery cannot be guaranteed, and there is no timeline that applies to everyone. Consult a health care professional before stopping or changing any substance, and do not use medications to try to restore fertility without supervision.

What tests might be considered?

Depending on your medical history and goals, your health care team may consider a semen analysis, a hormone evaluation, or other steps. The choice and interpretation of tests depend on an assessment of your individual case.
