Does Birth Control Affect Libido? What Research Shows

For millions of women worldwide, hormonal birth control is a reliable, convenient way to prevent pregnancy. But along with the benefits often comes a nagging question: Will this pill affect my sex drive?

If you’ve wondered whether your contraception is dampening your desire—or heard stories from friends who swear their libido plummeted after starting the pill—you’re not alone. Fear of side effects, including sexual changes, is one of the main reasons women either avoid hormonal contraceptives or stop using them altogether.

The relationship between birth control and libido is complex, and the research paints a nuanced picture. Here’s what the latest science actually says.

Understanding How Hormonal Contraceptives Work

Before diving into sexual effects, it helps to understand what these hormones are doing in your body.

Hormonal contraceptives—whether pills, patches, rings, implants, or injections—work primarily by suppressing ovulation. They do this by influencing the hypothalamic-pituitary-ovarian axis, the body’s natural hormonal control system.

But these hormones don’t act only on the ovaries. They affect tissues throughout the body that have sex steroid receptors, including the genitals, skin, and crucially, the brain. In the central nervous system, hormonal contraceptives modulate key neurotransmitters like GABA, serotonin, and dopamine, as well as neurosteroids such as allopregnanolone and β-endorphin . This helps explain why some women experience mood changes, anxiety, or shifts in sexual desire while using hormonal birth control.

One of the most significant hormonal changes involves testosterone. Combined oral contraceptives (COCs) typically decrease circulating levels of free testosterone while increasing sex hormone-binding globulin (SHBG), which binds to testosterone and makes it less biologically available. Since testosterone plays a role in sexual desire for women, this mechanism is a primary suspect in libido-related side effects.

What the Research Shows: Mixed Evidence

The scientific evidence on hormonal contraception and sexual function is surprisingly inconsistent. A 2024 review published in Obstetrics and Gynecology Clinics notes that “although specific hormonal contraceptives have been implicated in sexual dysfunction among these women, the correlation lacks consistency across studies and varies between different types of hormonal contraception”.

This inconsistency is reflected in the European Society of Sexual Medicine’s (ESSM) position statement, which concluded that “the effects of hormonal contraceptives on sexual function have not been well studied and remain controversial”.

The Majority Experience No Significant Change

Despite widespread concern, most women using hormonal contraception report no significant change in their libido.

A systematic review of 36 studies spanning 1978 to 2011, which included nearly 13,700 women, found that among combined oral contraceptive users, 85% reported either an increase or no change in libido. Only 15% reported a decrease .

These findings align with the ESSM’s assessment that “a minority of women experience a change in sexual functioning with regard to general sexual response, desire, lubrication, orgasm, and relationship satisfaction”.

But for Some Women, Changes Are Real

While most women tolerate hormonal contraceptives well, a subset experience significant sexual side effects.

A 2018 randomized controlled study examining the effects of combined oral contraceptives on sexual function found measurable declines in certain measures. After five cycles of using a levonorgestrel-containing pill, women experienced significant decreases in:

• Total FSFI scores (Female Sexual Function Index) from 28.7 to 25.6
• Arousal scores from 5.0 to 4.5
• Lubrication scores from 5.2 to 4.6
• Pain scores from 4.9 to 4.5 

Notably, these declines were not observed with a drospirenone-containing pill in the same study, suggesting that the specific type of progestin matters.

Why Do Effects Vary So Much?

The inconsistency in research findings reflects several factors:

1. Different Hormonal Formulations

Not all birth control is created equal. Different estrogen doses and different progestin types can have vastly different effects on the body. Some progestins are androgenic (mimicking testosterone’s effects), while others are anti-androgenic (blocking testosterone’s effects).

Antiandrogenic progestins such as drospirenone or cyproterone acetate appear more likely to negatively affect sexual arousal, lubrication, and orgasm . Conversely, formulations containing estradiol or estetrol combined with anti-androgenic progestins may offer a more favorable neuroendocrine profile, particularly for women with a history of mood disorders or hormonal sensitivity.

2. Individual Biological Differences

Women’s bodies respond differently to hormonal changes. Some women are more sensitive to shifts in testosterone or other hormones. A 2018 study found that women with higher free testosterone levels during contraceptive use showed significantly better effects on sexual arousal and desire compared to those with lower levels.

3. Method of Administration

The route of administration matters. The ECHO randomized trial, which followed nearly 8,000 women across four African countries, compared three different contraceptive methods and found small but significant differences:

• Women using the depot medroxyprogesterone acetate (DMPA-IM) injection reported the lowest prevalence of sexual activity and the highest rates of decreased sexual desire
• Women with the levonorgestrel implant fell in the middle
• Women using the copper IUD (a non-hormonal method) reported the highest sexual activity and lowest rates of decreased desire 

This pattern suggests that the method of administration and the specific hormone formulation both play roles in sexual outcomes.

Beyond Hormones: Psychological Factors

It’s important to recognize that birth control affects libido through more than just hormonal mechanisms. The ESSM notes that hormonal contraceptives can impact sexuality through several pathways:

Positive effects:

• Reduced fear of pregnancy: For many women, the security of effective contraception allows for more liberated, spontaneous sexuality
• Decreased gynecological complaints: Relief from conditions like endometriosis-associated pain or dysmenorrhea can improve sexual experience
• Improved body image: Benefits such as reduced acne or hirsutism (excess hair growth) can boost confidence

Potential negative effects:

• Direct hormonal influences on libido and arousal
• Changes in relationship dynamics when partners’ hormonal compatibility shifts
• Individual vulnerability to neuroendocrine changes

As the ESSM emphasizes, a careful baseline psychological, sexual, and relational assessment is necessary to evaluate eventual effects of hormonal contraceptives at follow-up.

How Common Is It to Stop Contraception Due to Sexual Side Effects?

A 2025 global review examining 64 studies conducted between 2004 and 2023 found that approximately 5% of people who stopped using contraception—despite still wanting to prevent pregnancy—did so because of concerns related to their sex lives.

These concerns included:

• Decreased libido
• Discomfort during sex
• Worries about how a method might affect a partner’s sexual experience

The researchers noted that sexual concerns are as common a reason for discontinuing contraception as cost or lack of access—yet they receive far less research attention . This finding underscores that sexual well-being is not a secondary consideration in contraceptive care but central to whether a method is acceptable and sustainable for users.

New Developments: Male Birth Control and Libido

The connection between hormonal contraception and libido isn’t only a women’s health issue. Research into male hormonal contraception offers an interesting parallel.

A Phase 1 study of an experimental male oral contraceptive called 11-beta-MNTDC (11-beta-methyl-19-nortestosterone dodecylcarbonate) found that the drug effectively decreased sperm production while preserving libido. Among 40 healthy men who took the drug daily for 28 days, only five reported mildly decreased sex drive, and two described mild erectile dysfunction. Notably, sexual activity was not decreased, and no participant stopped taking the drug because of side effects.

This research, while preliminary, highlights that hormonal approaches to contraception don’t necessarily have to compromise sexual function—and may offer insights for improving existing female formulations.

What to Do If You’re Concerned About Libido

If you’re using hormonal contraception and concerned about changes in your sexual desire, here are practical steps to consider:

1. Give It Time

Many side effects, including sexual changes, may stabilize after the first few months of use as your body adjusts to the hormones. However, if symptoms persist beyond 3-6 months, don’t dismiss them.

2. Consider the Formulation

If you’re on a combined pill, the type of progestin matters. Anti-androgenic progestins (such as drospirenone) may be more likely to affect libido. Conversely, some women do better with androgenic progestins (such as levonorgestrel). Work with your provider to find a formulation that works for your body.

3. Explore Non-Hormonal Options

If hormonal methods consistently cause unwanted sexual side effects, non-hormonal options like the copper IUD may be worth considering. The ECHO trial found that women using copper IUDs reported the highest levels of sexual activity and lowest rates of decreased desire.

4. Address Other Factors

Libido is influenced by far more than contraception. Stress, relationship dynamics, sleep quality, mental health, and general well-being all play major roles. Don’t assume birth control is the only factor—but don’t dismiss it either.

5. Talk to Your Provider

Sexual side effects are a valid reason to reconsider your contraceptive choice. If your healthcare provider dismisses your concerns, consider seeking a second opinion. The 2024 Oxford Academic review emphasizes that “consideration of sexual dysfunction when presenting and prescribing hormonal contraception is essential for informed consent, shared decision making, and ensuring reliable contraceptive choices”.

The Bottom Line

So, does birth control affect libido? The answer is: it depends.

• For most women (about 85%), hormonal contraception does not significantly decrease libido.
• For a minority (about 15%), it can cause measurable declines in desire, arousal, and lubrication.
• For some women, birth control actually improves sexual experience by reducing pregnancy anxiety or alleviating painful gynecological conditions.
• The specific formulation matters significantly—different progestins have different effects.
• About 5% of women stop contraception due to sexual side effects, highlighting that this is a meaningful concern.

The relationship between hormonal contraception and libido is deeply individual. What works beautifully for one woman may not work for another. The key is not to dismiss sexual side effects as “all in your head” or an unavoidable trade-off for effective contraception.

As the ESSM concluded, while the evidence is controversial and more research is needed, a thorough baseline assessment and individualized counseling are essential for optimal contraceptive care . Your sexual well-being deserves to be part of the conversation.
