Does Zoloft Make It Hard to Ejaculate?

Yes, Zoloft commonly causes delayed ejaculation or difficulty reaching orgasm in men. This side effect occurs because sertraline increases serotonin levels, which can interfere with the sexual response cycle. Studies show that 20-30% of men taking SSRIs like Zoloft experience some form of sexual dysfunction. The effect typically develops within the first few weeks of treatment and may persist throughout therapy. Some men experience complete inability to ejaculate, while others notice significantly delayed climax. The severity often correlates with dosage - higher doses generally cause more pronounced effects. If this side effect is problematic, discuss alternatives with your doctor rather than stopping medication abruptly.
