IUDs Generally Do Not Suppress Sexual Desire
Based on the available evidence, IUDs—particularly copper IUDs—do not suppress sexual desire and may actually be associated with better sexual function compared to some hormonal contraceptive methods. The evidence suggests that copper IUDs have minimal to no negative impact on libido, while levonorgestrel IUDs show mixed but generally neutral effects on sexual desire.
Evidence-Based Breakdown by IUD Type
Copper IUD (Non-Hormonal)
The copper IUD appears to be the contraceptive method with the least negative impact on sexual desire:
- In a large randomized trial, copper IUD users reported the lowest rates of decreased sexual desire (0.5%) compared to DMPA (1.6%) and the implant (1.1%) 1
- Copper IUD users had an 18.3% prevalence of lacking interest in sex, which served as the reference (lowest) group when comparing contraceptive methods 2
- A systematic review found copper IUDs to have a positive-to-neutral effect on sexual desire 3
Levonorgestrel IUD (Hormonal)
The hormonal IUD shows no significant suppression of sexual desire:
- No association was found between hormonal IUD use and lack of interest in sex compared to copper IUD users 2
- The systematic review concluded that LNG-IUDs are generally non-impactful on sexual desire 3
- Notably, LNG-IUDs may actually improve sexual pain, which could indirectly enhance overall sexual function 3
Comparative Context with Other Methods
To put this in perspective, methods that did show increased reports of decreased sexual desire compared to copper IUDs include:
- Depot medroxyprogesterone acetate (DMPA): 2.61 times more likely to report lack of interest in sex 2
- Vaginal ring: 2.53 times more likely 2
- Contraceptive implant: 1.60 times more likely 2
Clinical Implications
When counseling patients about IUDs and sexual function:
- Reassure patients that IUDs, particularly copper IUDs, are among the contraceptive methods least likely to affect sexual desire
- For patients concerned about libido, copper IUDs represent an excellent choice with no hormonal effects on sexual function
- Levonorgestrel IUDs offer the additional benefit of potentially reducing sexual pain while maintaining neutral effects on desire 3
- The prevalence of sexual dysfunction in IUD users (approximately 50%) 4, 5 appears related to other factors (age, BMI, relationship factors, sociocultural issues) rather than the IUD itself
Important Caveats
- Sexual dysfunction is multifactorial with many contributing factors beyond contraception, including relationship quality, stress, medical conditions, and sociocultural factors 4, 5
- The high baseline prevalence of sexual dysfunction in some populations (57% in one study) suggests that attributing sexual concerns solely to the IUD is inappropriate 4
- Individual variation exists, and some patients may experience changes in sexual function that they attribute to their IUD, though this is not supported by population-level data
Bottom line: IUDs do not suppress sexual desire and represent one of the best contraceptive options for women concerned about maintaining their libido. 6, 1, 3, 2
