Low libido at any age: what TikTok gets right and wrong

What did @drjenniferlincoln actually say?

Dr. Jennifer Lincoln, an OB-GYN with a large social following, kept it brief: low libido "can affect anybody at any age," it's only a clinical concern "if it bothers you or it's affecting your relationship," and the fix isn't just "buying a pill or a supplement from the internet." She invited viewers to reach out for individualized guidance. That's the whole video. No protocol, no product recommendation, no dramatic claim. Worth noting before we tear into it.

The tone is intentionally non-alarmist, which is actually rare for a topic that gets aggressively monetized by supplement brands and wellness influencers. She didn't diagnose anyone, didn't name a treatment, and didn't oversell the problem. Whether that level of vagueness is useful is a separate question.

Does the science back this up?

Yes, mostly. The claim that low libido has no age limit is well-supported, and the distress criterion she mentions maps directly onto how clinicians actually define the condition. The dismissal of internet supplements is the most clinically defensible thing she says.

Hypoactive Sexual Desire Disorder (HSDD) is defined in part by personal distress, a point codified in the DSM-5 and supported by population research. Shifren et al. (2008, Obstetrics and Gynecology) found that low desire was common across age groups in U.S. women, but distress about it varied significantly and independently of desire frequency. In other words, low libido without distress is not a disorder. That's exactly what Dr. Lincoln said.

For men, testosterone declines roughly 1-2% per year after age 30 (Harman et al., 2001, Journal of Clinical Endocrinology and Metabolism), but libido reduction in younger men is well-documented too, tied to stress, depression, medications, and relationship factors. The American Urological Association acknowledges low libido as a symptom of hypogonadism but notes it can occur without hormonal deficiency entirely.

What did they get wrong (or right)?

She got the distress criterion right, and that matters more than it sounds. She got the age point right. What she got fuzzy is the "lots of things that can be going on" without naming any of them, which is either responsible restraint or a missed educational opportunity depending on your view.

The supplement line is the strongest moment. The online libido supplement market is largely unregulated, and products marketed for sexual function frequently contain unlisted pharmaceutical ingredients. A 2021 analysis by Cohen et al. (JAMA Network Open) found that a significant proportion of sexual enhancement supplements contained undisclosed PDE5 inhibitors, which carry real cardiovascular risks. Telling people not to buy random pills off the internet is genuinely good public health advice.

What's missing: she doesn't mention that medications (antidepressants, beta blockers, hormonal contraceptives) are among the most common reversible causes of low libido. That omission won't hurt anyone watching, but it's a gap. She also doesn't distinguish between low libido as a standalone symptom versus as a sign of something systemic like thyroid dysfunction or hypogonadism, where clinical workup actually matters.

What should you actually know?

Low libido is real, common, and genuinely multifactorial. The distress criterion isn't a loophole, it's the actual clinical standard. If it doesn't bother you, it's not a problem by definition. If it does bother you, there are evidence-based paths forward that don't start with a supplement ad.

For people with confirmed hormonal causes, like low testosterone in men or menopause-related changes in women, treatments exist and have real evidence behind them. Testosterone therapy for hypogonadism in men is backed by multiple RCTs. For women, the picture is more complicated. Flibanserin (Addyi) is FDA-approved for HSDD in premenopausal women but has a modest effect size and meaningful side effect profile. Bremelanotide (Vyleesi) is another option. Neither is a magic fix.

• Psychological and relationship factors contribute to low libido across all age groups and often respond better to therapy than to pharmacology.
• SSRIs and SNRIs are among the most common medication-related causes of reduced libido. This is reversible in most cases with dose adjustment or switching agents.
• If you're experiencing sudden or significant change in sexual desire, a basic workup (thyroid, hormonal panel, medication review) is a reasonable first step before anything else.
• Don't take sexual enhancement supplements without reviewing the label with a clinician. Undisclosed active ingredients are a documented safety problem in this category.
