Key takeaways
- Antidepressant-related ED: the best male-specific evidence. 15 mg twice daily improved erectile function in men taking fluoxetine.
- General erectile dysfunction: small, mostly uncontrolled studies with mixed results.
- Sperm quality: early studies conflict. Not enough evidence to recommend it.
- Testosterone: no good human evidence that saffron raises it.
- Mood and stress: the strongest overall evidence, and it applies to men too.
Saffron and Erectile Function
Antidepressant-related ED: the strongest evidence
SSRIs such as fluoxetine commonly cause erectile and orgasm problems. In a 4-week randomized, placebo-controlled trial of men with fluoxetine-related sexual dysfunction, 15 mg of saffron twice daily improved erectile function and intercourse satisfaction scores (Modabbernia 2012).
General erectile dysfunction: weaker evidence
A small open-label pilot (no placebo group) gave men with ED 200 mg of saffron a day for 10 days and reported better erectile function scores (Shamsa 2009). Without a placebo group, that result is hard to interpret, and other studies have been mixed. Overall, saffron is not a proven ED treatment.
ED can be an early sign of heart disease, diabetes or hormone problems. See a doctor before treating it with supplements; effective, well-studied medicines exist.
Saffron and Libido
A 2019 meta-analysis of saffron and sexual dysfunction pooled trials in men and women and found improvements in several measures of sexual function, though the studies were small and varied (Ranjbar 2019). Part of the effect may come from mood: low mood and stress are big libido killers, and mood is saffron's best-studied target.
Saffron, Sperm and Fertility
Early results conflict. An uncontrolled study of infertile men reported improved sperm shape and motility after 3 months of saffron (Heidary 2008), but a later randomized, placebo-controlled trial found no meaningful improvement in sperm parameters with 60 mg/day over 26 weeks (Safarinejad 2011). Bottom line: there isn't enough evidence to take saffron for male fertility. Couples trying to conceive should see a fertility specialist.
Does Saffron Increase Testosterone?
There's no good human evidence that it does. Some animal studies report hormonal changes, but no well-designed human trial shows saffron meaningfully raises testosterone. Be wary of "testosterone booster" products that lean on saffron for this claim.
Saffron for Men's Mood and Stress
Men are less likely to seek help for low mood, but saffron's mood evidence applies equally to them. Meta-analyses find 30 mg/day improves mild-to-moderate depressive symptoms, and the affron® trials found benefits for stress and sleep (Marx 2019; Kell 2017). See saffron for mood and saffron for sleep.

Frequently Asked Questions
Does saffron work like Viagra?
No. Saffron doesn't act on the same pathway as PDE5 inhibitors such as sildenafil, and its effects on erections are much weaker and less certain.
How much saffron should a man take for libido?
The positive trial in men on fluoxetine used 15 mg twice daily (30 mg/day) for 4 weeks. Evidence for libido in men not on SSRIs is limited.
Is saffron good for men's fertility?
The evidence conflicts: an uncontrolled study suggested benefits, but a placebo-controlled trial found none. It isn't recommended for fertility.
Can saffron cause erectile problems?
That isn't a reported side effect at normal doses. If anything, trials suggest small improvements in sexual function.
