Does an IUD Affect Your Sex Drive?

For most people, an IUD has little to no measurable effect on sex drive. The broadest research, including a systematic review of studies on both hormonal and non-hormonal IUDs, found a “positive-to-neutral” effect on sexual desire overall, with other aspects of sexual function like arousal, lubrication, orgasm, and satisfaction also largely unaffected.¹ That said, a meaningful minority of users do notice a change, and the type of IUD, individual hormone sensitivity, and even the psychological relief of having reliable contraception all play into how it shakes out.

What the Research Shows for Most Users

The clearest takeaway from the clinical evidence is that IUDs, as a category, do not cause widespread drops in libido. A large cross-sectional study comparing hormonal IUD users, pill users, patch users, and copper IUD users found no association between any of those methods and a lack of interest in sex. About one in five copper IUD users in that study reported low sexual interest, but the rate was not meaningfully different among hormonal IUD users.² A position statement from the European Society of Sexual Medicine put it plainly: available evidence indicates that only a minority of women experience a change in sexual functioning with hormonal contraceptives, including desire, lubrication, orgasm, and relationship satisfaction.³

A head-to-head comparison of hormonal IUD users and copper IUD users found no significant difference in the prevalence or type of sexual dysfunction between the two groups, and no difference in depressive symptoms, general well-being, or relationship quality either.⁴ Another study found no difference in decreased sexual desire between IUD users and oral contraceptive users.⁵ The pattern across these studies is consistent: IUDs, on average, do not stand out as libido suppressors compared to other contraceptive methods or to non-hormonal baselines.

Hormonal Versus Copper IUDs and Desire

Though the average outcomes look similar, there is one consistent wrinkle in the data. When researchers ask users how they perceive their contraceptive’s effect on desire, hormonal IUD users report negative changes more often than copper IUD users do. A survey of young women found that roughly 28% of hormonal IUD users said their method had negatively affected their sexual desire, compared with about 10% of copper IUD users.⁶ That gap is real and statistically significant, even though objective measures of sexual function in other studies don’t show the same divide.

How do you square those two findings? Part of the answer is the difference between perceived change and measured dysfunction. If you ask someone a direct question about whether their contraceptive hurt their sex drive, you get one picture. If you give them a validated sexual function questionnaire that measures desire, arousal, orgasm, and satisfaction, you often get a different picture. The head-to-head study that found no significant difference in sexual dysfunction prevalence between hormonal and copper IUD users used a standardized questionnaire, while the survey finding that gap relied on self-reported perception.⁴ Neither approach is wrong, but they measure different things. Your lived experience of desire is shaped by more than hormone levels.

What Happens Hormonally With a Levonorgestrel IUD

The hormonal IUD releases levonorgestrel, a synthetic progestin, directly into the uterus. Unlike the pill or the shot, most of the hormone stays local. That distinction matters for sex drive because the main hormonal pathway people worry about involves testosterone. Testosterone plays a role in libido, and some systemic hormonal contraceptives lower circulating testosterone or raise sex hormone-binding globulin (SHBG), a protein that ties up free testosterone and takes it out of circulation.

An ancillary study from a large randomized trial compared the hormonal profiles of copper IUD users, injectable contraceptive users, and implant users over six months. Copper IUD users showed no change in testosterone, SHBG, or free testosterone. Injectable and implant users, by contrast, saw significant drops in testosterone and shifts in SHBG.⁷ That study used the copper IUD as a non-hormonal reference, so it didn’t measure hormonal IUD users directly. But separate research on the hormonal IUD found that SHBG and total testosterone concentrations didn’t change during its use, unlike oral levonorgestrel, which did lower SHBG.⁸

An earlier, smaller study found a dip in SHBG after hormonal IUD insertion, but the decrease was not statistically significant. What was significant was the correlation between levonorgestrel levels and SHBG levels, suggesting that in users who absorb more of the hormone systemically, the effect on binding proteins could be more pronounced.⁹ This individual variation likely explains why most hormonal IUD users notice nothing, while a smaller group feels a genuine dampening of desire. How much levonorgestrel leaks into the bloodstream varies from person to person, and the downstream effects on testosterone availability vary accordingly.

How an IUD Can Actually Boost Your Sex Life

Much of the conversation around IUDs and sex drive focuses on what might go wrong. But for many users, the net effect on their sex life is positive, and the reasons are not purely hormonal. A qualitative study of young women using IUDs identified several ways the device enhanced sex. The most commonly mentioned benefit was security: knowing you have one of the most effective forms of contraception can reduce anxiety during sex. That anxiety reduction matters more than people often give it credit for, because worry about pregnancy is a genuine libido dampener for a lot of people. Closely tied to that was spontaneity. With no pill to remember or condom negotiation to navigate, IUD users described sex as more free-flowing.¹⁰

Another benefit that comes up, particularly for people switching from systemic hormonal methods, is the sense that their body is running more naturally. Some women in that study described relief at not flooding their system with hormones, even when they had a hormonal IUD. The “low hormone” framing helped them feel their sexual responses were more authentically their own. For hormonal IUD users specifically, a systematic review noted a positive impact on sexual pain, meaning that users who previously had painful periods or pain during sex often saw improvement.¹ That alone can transform someone’s sex life in ways that dwarf any marginal hormone effect.

Women in Uganda who received IUDs after an abortion procedure reported improved lubrication and reduced pain during sex compared with their previous experience on injectable contraceptives. Several couples described the change as significant enough to recommend IUDs to friends.¹¹ While that study was set in a specific cultural and clinical context, the underlying theme, that switching from a systemic hormonal method to an IUD often feels like a net gain for sexual well-being, appears repeatedly across the literature.

Side Effects That Can Indirectly Dampen Desire

If most studies show IUDs are neutral-to-positive for desire, why do some people still experience a real drop in libido? Often, it is not the IUD’s effect on hormones that is the problem. It is the side effects that live alongside it.

Irregular bleeding and spotting are common in the first few months with either type of IUD, and they affect how people feel about sex. Nobody feels particularly amorous when dealing with unexpected bleeding, and the uncertainty of not knowing whether you’ll bleed during sex can create its own layer of avoidance. The qualitative study of young women described bleeding and cramping as one of the key themes affecting sexual acceptability.¹⁰ Copper IUDs tend to cause heavier and longer periods, especially in the first several months. Hormonal IUDs typically cause irregular spotting early on, with many users eventually seeing lighter periods or none at all.

Then there is the string. IUDs have thin strings that hang through the cervix so a provider can remove the device later. Some partners report feeling the strings during sex, which, while not painful, can be distracting or off-putting. That same qualitative study found that the string was one of six themes women raised when discussing the sexual experience of having an IUD. The good news is that strings soften over time, and a provider can trim them if they are causing issues. But in the early weeks, a partner’s reaction to the string can put a damper on things, especially if neither person expected it.

Cramping in the days after insertion can also temporarily tank interest in sex. This is a short-term issue, usually resolving within a week or two, but worth knowing about so you do not mistake post-insertion discomfort for a longer-term libido change.

The Role of Expectations and Psychology

One of the most underappreciated factors in how contraception affects sex drive is what you expect it to do. A provocative finding from research on oral contraceptives illustrates this well: women given a placebo pill reported a similar side effect profile to those taking actual hormonal pills, including mood changes and shifts in desire.¹² The researchers argued that much of what gets attributed to hormonal contraception may stem from a psychological response to the act of using contraception itself. If you have heard from friends, online forums, or social media that your IUD will kill your sex drive, the expectation can become a self-fulfilling prophecy.

This does not mean the experience is not real. If your desire drops after getting an IUD, you feel it regardless of the cause. But it does mean that the picture is more layered than “hormones go in, libido goes out.” Relationship dynamics, stress, body image, how you feel about the insertion experience, whether you chose the IUD freely or felt pressured, and even the quality of your sleep all feed into desire. Any of these can shift around the same time you get a new contraceptive, making it easy to attribute the change to the device.

Researchers have noted this repeatedly when trying to study contraception and sexual function. The European Society of Sexual Medicine’s position statement emphasized that the effects of hormonal contraceptives on sexual function remain “controversial” in large part because isolating the hormonal signal from all the psychological and relational noise is extremely difficult.³

Who Is Most Likely to Notice a Change

While most users will not experience a meaningful shift, a few patterns emerge for people who do. First, people who are sensitive to progestins in general tend to be more sensitive to the hormonal IUD as well. If you had mood or libido changes on the pill, particularly on progestin-only pills, you have a slightly higher baseline risk of noticing something similar with a hormonal IUD. The dose is much lower and mostly local, but it is not zero systemically.

Second, people switching from a method that was already suppressing their sex drive, like a hormonal injection or a combined pill that raised their SHBG significantly, sometimes experience a rebound increase in desire after getting an IUD, especially a copper one. The ECHO trial data showed that injectable and implant users had measurably lower testosterone at six months compared with copper IUD users, whose levels stayed flat.⁷ If you switch from one of those methods to a copper IUD, the hormonal environment shifts in a direction that could support higher desire.

Third, people whose previous contraceptive method caused physical side effects during sex, like vaginal dryness from the pill, may find that an IUD resolves those issues and their interest picks back up. It is easy to conflate discomfort-driven avoidance with low desire; when the discomfort disappears, the distinction becomes clear.

Copper IUDs and the “Hormone-Free” Question

Copper IUDs are often positioned as the truly hormone-free option, and in terms of sex drive, the data largely supports the idea that they are neutral. The ECHO trial showed copper IUD users had stable testosterone, SHBG, and free testosterone over six months, essentially serving as the control group.⁷ The study that asked copper IUD users directly about their sexual interest found that about 18% reported lacking interest, but that number is roughly in line with background rates of low desire in the general population, not something the IUD caused.²

Still, about 10% of copper IUD users in one survey did attribute a negative change in desire to the device.⁶ Since the copper IUD has no hormonal mechanism that would affect libido, those reports likely reflect the indirect pathways already discussed: heavier periods, cramping, anxiety about the device, or the nocebo effect of simply worrying that your contraception might change you. The copper IUD’s main sexual trade-off is physical: heavier, crampier periods in exchange for leaving your hormones entirely alone.

What to Do If You Think Your IUD Is Affecting Your Sex Drive

If you have had your IUD for a few months and feel like your desire has genuinely shifted, the first step is to separate the device from everything else going on. Has your stress level changed? Sleep? Relationship satisfaction? Medications? Depression and anxiety are common drivers of low desire and may have nothing to do with the IUD. Giving it an honest look before attributing the change to the device is worth doing.

If you have a hormonal IUD and strongly suspect it is the cause, one option is switching to a copper IUD, which removes the progestin variable entirely. That switch can be done in a single office visit. If you already have a copper IUD and are experiencing low desire, the IUD is almost certainly not the hormonal culprit, and looking at other factors becomes even more important.

Timing matters too. The first three to six months with any IUD involve an adjustment period where bleeding patterns, cramping, and body awareness are all in flux. Many of the negative perceptions reported in studies come from this early window. Researchers in the systematic review noted that longer-term data tended to show stable or improved sexual function, reinforcing the idea that the initial disruption settles.¹ If you are in the early months and feeling off, giving it more time before making a decision is reasonable, provided the symptoms are tolerable.

Why the Research Remains Messy

Anyone reading deeply into this topic will notice that the evidence is frustratingly uneven. Some studies use validated sexual function questionnaires, others rely on a single yes-or-no question. Sample sizes range from a few dozen to several thousand. Study populations vary in age, relationship status, and prior contraceptive experience, all of which affect desire independently. Blinding is virtually impossible: you know whether you have an IUD, and you usually know whether it is hormonal. That awareness opens the door to expectation effects in every study.

The European Society of Sexual Medicine acknowledged this explicitly, calling the area “controversial” and “not well studied” despite decades of contraceptive use.³ One of the fundamental challenges is that desire is not a single thing with a simple dial. It is shaped by hormones, psychology, relationship context, physical comfort, cultural expectations, and individual neurobiology. Isolating the specific contribution of a small plastic device in the uterus, particularly one whose hormonal dose is already tiny, may always be difficult. What the data can say with reasonable confidence is that any effect is small on average, and that for many users the indirect benefits of reliable, low-maintenance contraception end up being the bigger story for their sex life.
