Dilation and curettage (D&C) rarely causes infertility but may increase risk if complications like scarring occur.
Understanding Dilation and Curettage (D&C)
Dilation and curettage, commonly known as D&C, is a surgical procedure used to remove tissue from the inside of the uterus. It involves dilating the cervix and scraping or suctioning the uterine lining. This procedure is frequently performed for diagnostic purposes, to treat certain uterine conditions, or following a miscarriage.
The reasons for undergoing a D&C vary widely. It can be used to investigate abnormal uterine bleeding, remove retained products of conception after miscarriage or abortion, or obtain tissue samples for biopsy. Despite its routine nature, many women worry about potential complications, especially regarding fertility.
How Does a D&C Work?
During a D&C, the cervix is gently dilated using specialized instruments. Once open, a curette—a small spoon-shaped tool—is inserted into the uterus to scrape away tissue. Alternatively, suction devices may be used to remove tissue more gently.
The procedure is usually quick, lasting between 10 to 20 minutes. It’s often done under local or general anesthesia depending on the clinical situation and patient preference. Recovery times are typically short; most women resume normal activities within a day or two.
While effective for its intended purposes, D&C carries some risks that could potentially impact reproductive health.
Potential Risks of D&C Related to Fertility
The primary concern linking D&C with infertility centers around damage to the uterine lining and structure. Here are some key risks:
- Asherman’s Syndrome: This condition involves formation of scar tissue (intrauterine adhesions) inside the uterus after trauma such as repeated or aggressive curettage.
- Endometrial Damage: Excessive scraping can thin the endometrium (uterine lining), impairing its ability to support embryo implantation.
- Cervical Injury: Although rare, dilation can sometimes damage the cervix leading to incompetence or narrowing.
- Infection: Post-procedure infections may cause inflammation and scarring that affect fertility.
Most women experience no long-term issues after a single uncomplicated D&C. However, repeated procedures or overly aggressive scraping increase risks significantly.
Asherman’s Syndrome: The Main Culprit
Asherman’s Syndrome is often cited when discussing infertility following D&C. It occurs when scar tissue forms inside the uterine cavity, partially or completely obliterating it. This scarring prevents normal endometrial regeneration and can block implantation.
Symptoms include menstrual irregularities such as lighter periods or amenorrhea (absence of menstruation), pelvic pain, and recurrent pregnancy loss. Diagnosis usually requires hysteroscopy—a direct visual inspection of the uterine cavity.
Treatment involves surgical removal of adhesions under hysteroscopic guidance followed by estrogen therapy to promote healing. While many women regain fertility post-treatment, severe cases may have persistent difficulties conceiving.
Statistical Insights: Fertility Impact Post-D&C
Understanding how often infertility occurs after D&C requires looking at clinical data:
| Study/Source | Reported Infertility Rate After D&C | Notes |
|---|---|---|
| American Journal of Obstetrics & Gynecology (2014) | Less than 5% | Infertility mainly linked with multiple procedures or infection. |
| Fertility and Sterility (2017) | Up to 20% in high-risk groups | Higher rates in women with repeated miscarriages requiring multiple D&Cs. |
| Cochrane Review (2020) | N/A – Focus on miscarriage management methods | Surgical vs medical management showed no significant difference in long-term fertility. |
These figures indicate that while isolated D&Cs carry a low risk for infertility in most cases, repeated procedures raise concerns considerably.
The Role of Procedure Frequency and Technique
Repeated dilation and curettage procedures elevate the risk of scarring dramatically. Each time the uterine lining is disturbed, there’s potential for adhesions forming during healing.
Modern techniques aim to minimize trauma by using suction rather than sharp curettes when possible. Medical alternatives like misoprostol for miscarriage management have also reduced reliance on surgical intervention.
Physician skill and experience matter greatly too—gentle dilation and careful tissue removal reduce complications compared to rushed or forceful procedures.
The Biological Mechanisms Behind Infertility Post-D&C
Fertility depends heavily on a healthy endometrium capable of supporting embryo implantation and growth. When this lining is damaged repeatedly through mechanical scraping:
- The basal layer responsible for regenerating new endometrium may be destroyed.
- The uterus may develop fibrosis—dense scar tissue—that lacks normal vascularization.
- The uterine cavity shape can become distorted due to adhesions tethering walls together.
- Cervical damage can alter mucus production affecting sperm passage.
These changes create an inhospitable environment for fertilization and implantation despite normal ovulation and egg quality.
Infections following surgery exacerbate inflammation leading to further fibrosis. This highlights why sterile technique and prompt treatment of any infection are vital post-D&C.
Cervical Factors Affecting Fertility After D&C
Although less common than uterine issues, cervical trauma during dilation can cause problems:
- Cervical stenosis: Narrowing or closure of the cervical canal impeding sperm entry.
- Cervical incompetence: Weakening that might cause preterm labor in future pregnancies.
Both conditions require specialized interventions but are not frequent outcomes from properly performed D&Cs.
Treatment Options If Infertility Occurs After D&C
If infertility develops post-D&C due to scarring or adhesions, several approaches exist:
Surgical Adhesion Removal (Hysteroscopic Adhesiolysis)
This minimally invasive surgery uses a camera inserted into the uterus to visualize scars directly. Surgeons carefully cut away fibrous bands restoring normal cavity shape. Follow-up hormonal therapy promotes healthy endometrial regrowth.
Success rates vary but many women conceive naturally after treatment if no other fertility issues exist.
Cervical Procedures
For cervical stenosis, gentle dilation under anesthesia can reopen the canal. In cases of incompetence, cerclage stitches provide mechanical support during pregnancy reducing miscarriage risk.
Assisted Reproductive Technologies (ART)
If natural conception remains challenging despite corrective surgeries, IVF (in vitro fertilization) offers hope by bypassing some uterine factors temporarily through embryo transfer techniques optimized for thin linings.
Preventive Measures To Protect Fertility During D&C
Minimizing fertility risks starts before surgery:
- Adequate Counseling: Patients should understand risks especially if multiple procedures might be necessary.
- Surgical Technique: Favor suction over sharp curettage whenever possible; avoid excessive scraping.
- Avoid Repetition: Consider medical alternatives like misoprostol for incomplete miscarriages unless contraindicated.
- Aseptic Protocols: Strict sterile technique reduces infection chances dramatically.
- Tissue Sampling Precision: Targeted biopsies rather than broad curettage limit unnecessary trauma.
Following these guidelines helps preserve uterine integrity while still achieving diagnostic or therapeutic goals effectively.
The Controversy Surrounding Can D&C Cause Infertility?
Some clinicians argue that modern improvements have made infertility after single uncomplicated D&Cs exceedingly rare. Others caution that any invasive procedure carries inherent risks that must not be overlooked—especially in women desiring future pregnancies.
Studies often show conflicting results because infertility is multifactorial: age, prior pregnancy history, underlying conditions like endometriosis also play roles independent of surgery itself.
Still, it’s prudent not to dismiss concerns outright but weigh benefits against potential harms carefully before proceeding with repeat interventions.
The Role of Alternatives in Reducing Fertility Risks
Medical management options have gained traction as safer alternatives when appropriate:
- Mifepristone plus misoprostol: Used effectively for early pregnancy loss avoiding surgery altogether in many cases.
- Methotrexate: Sometimes employed for ectopic pregnancies avoiding invasive procedures impacting uterus directly.
These methods reduce physical trauma preserving reproductive anatomy but may not suit all clinical scenarios.
Taking Control: What Patients Should Know Before Undergoing a D&C
Open communication with healthcare providers is crucial:
- Discuss fertility goals upfront: Make sure your doctor understands your desire for future pregnancies so they tailor care accordingly.
- Avoid unnecessary repeat procedures:If symptoms persist after one D&C ask about alternative investigations rather than jumping back into surgery immediately.
- Know your options:If medical management applies ask about pros/cons compared with surgical approach based on your unique situation.
- Mental preparation helps too;Anxiety about fertility outcomes can be eased by understanding realistic risks versus benefits clearly from trusted sources rather than rumors online.

Frequently Asked Questions
Can D&C Cause Infertility Due to Scarring?
D&C can rarely cause infertility if scarring, known as Asherman’s Syndrome, develops inside the uterus. This scar tissue may interfere with embryo implantation, reducing fertility. However, most women do not experience scarring after a single uncomplicated procedure.
How Does a D&C Affect Fertility?
The procedure itself usually does not affect fertility when done carefully. Risks arise if excessive scraping damages the uterine lining or if complications like infection occur, potentially impairing the uterus’s ability to support pregnancy.
Is Repeated D&C More Likely to Cause Infertility?
Yes, repeated or aggressive D&C procedures increase the risk of uterine damage and scarring. This can lead to infertility issues by disrupting the normal uterine environment necessary for embryo implantation and growth.
Can Infection After D&C Lead to Infertility?
Post-procedure infections can cause inflammation and scarring inside the uterus, which may affect fertility. Prompt treatment of any infection following a D&C is important to minimize this risk and preserve reproductive health.
What Are the Chances of Infertility After a Single D&C?
The likelihood of infertility after one uncomplicated D&C is very low. Most women recover fully without long-term effects on fertility, especially when the procedure is performed gently and under appropriate medical care.
Conclusion – Can D&C Cause Infertility?
Dilation and curettage itself rarely causes infertility when performed carefully once or twice without complications. The main threat arises from excessive trauma leading to intrauterine adhesions known as Asherman’s syndrome which impairs implantation capability significantly.
Repeated procedures increase this risk substantially along with infections or improper technique contributing further damage to uterine lining integrity. Fortunately modern surgical methods combined with growing use of medical alternatives help reduce these adverse outcomes today more than ever before.
If concerns arise about fertility following a D&C consult your gynecologist promptly—diagnostic tools like hysteroscopy can detect problems early allowing effective treatment options such as adhesion removal surgeries which restore reproductive potential in many cases.
In summary: while it’s natural to worry about “Can D&C Cause Infertility?” evidence shows it’s uncommon but possible mostly linked with avoidable complications making thorough patient education plus cautious surgical practice essential safeguards against permanent harm.
