Can a Man Take Finasteride While Trying to Conceive?

What Is Finasteride?

Finasteride is a prescription medication commonly used to treat:

• Male pattern hair loss (androgenetic alopecia)

• Enlarged prostate (benign prostatic hyperplasia or BPH)

It works by blocking the conversion of testosterone into dihydrotestosterone (DHT), a hormone linked to hair loss and prostate growth.

While finasteride is effective for these conditions, many men wonder: Is it safe to take finasteride when trying to have a baby?

Does Finasteride Affect Male Fertility?

Research suggests that finasteride may affect fertility in some men, but the impact is usually reversible after stopping the drug. Possible effects include:

• Reduced sperm count: Some studies report a temporary decrease in sperm concentration.

• Changes in sperm motility and volume: Finasteride may affect how sperm move or the amount of semen produced.

• Hormonal changes: By lowering DHT, finasteride alters the hormone balance that can indirectly affect reproductive health.

However, most men do not experience permanent infertility, and sperm quality typically improves within a few months of stopping finasteride.

Is Finasteride Safe for Pregnant Partners?

One of the main concerns is exposure during pregnancy. Finasteride can cause birth defects in male fetuses if a pregnant person is directly exposed to the drug (such as by handling crushed or broken tablets).

However, studies show that the amount of finasteride passed into semen is extremely low and unlikely to harm a partner or a developing baby. Despite this, some healthcare providers recommend caution if a couple is actively trying to conceive.

Should Men Stop Finasteride When Trying to Conceive?

The answer depends on your personal situation:

• Mild hair loss concerns: If you are only taking finasteride for cosmetic reasons, your doctor may recommend stopping the medication temporarily while trying to conceive.

• Severe hair loss or prostate condition: If stopping finasteride would significantly impact your quality of life or health, your provider may advise continuing.

• Fertility concerns: If you and your partner have been trying to conceive without success, your doctor may suggest discontinuing finasteride for at least 3–6 months to see if sperm quality improves.

Alternatives to Consider

If you’re worried about fertility but still want to address hair loss, possible alternatives include:

• Topical minoxidil (Rogaine), which does not affect hormones.

• Low-level laser therapy or hair restoration procedures.

• Lifestyle changes to support hair health (diet, stress reduction).

Key Takeaways

• Men can take finasteride while trying to conceive, but it may temporarily lower sperm quality in some cases.

• The small amount of finasteride found in semen is unlikely to harm a partner or pregnancy.

• If you’re struggling with fertility, consider pausing finasteride use and discussing options with your doctor.

• Any decision should balance fertility goals, health needs, and hair loss management.

Does finasteride affect sperm count?

Yes. Finasteride can lower sperm count, motility, or semen volume in some men, but these effects are usually temporary and improve after stopping the medication.

Can finasteride harm my partner if we’re trying to conceive?

The amount of finasteride found in semen is extremely low and unlikely to affect a partner or a developing baby. The main risk comes from pregnant individuals handling crushed or broken tablets.

Should I stop taking finasteride while trying to get my partner pregnant?

Not always. Some men continue finasteride without issues, but if you have fertility concerns, your doctor may recommend pausing it for 3–6 months to see if sperm quality improves.
