Surgical abortion is one of the safest medical procedures performed today. The mortality rate is approximately 0.5 per 100,000 procedures, making it roughly 44 times safer than carrying a pregnancy to term, which has a mortality rate of about 23.5 per 100,000 births. The overall complication rate is low, and the vast majority of people resume normal activities the next day.
How Safe It Is by the Numbers
A 2024 analysis published in JAMA Network Open calculated the abortion-related mortality rate in the United States at 0.538 per 100,000 procedures in 2021. For context, the pregnancy-related mortality rate that same year was 23.5 per 100,000 births. That gap is significant: dying from a surgical abortion is an extraordinarily rare event, far rarer than the risks of pregnancy and childbirth themselves.
For first-trimester procedures (the most common type), the success rate of vacuum aspiration exceeds 99%. In a large study of nearly 2,400 patients at up to six weeks of pregnancy, only 0.25% needed any additional procedure afterward. Even studies looking at slightly later gestations, up to 10 weeks, found complication rates of just 2.1% to 2.5%, with no significant difference between manual and electric vacuum methods. These complications are overwhelmingly minor, such as incomplete tissue removal that requires a brief follow-up.
Second-trimester procedures carry slightly higher risks, as expected with any procedure performed later in pregnancy. An audit of over 2,100 second-trimester procedures at an Australian hospital found an overall complication rate of 2.17% and a major complication rate of just 0.55%. A separate analysis of more than 4,500 second-trimester procedures found uterine perforation occurred in only 0.1% of cases and cervical injury in 3.8%.
First Trimester vs. Second Trimester Techniques
The specific surgical method depends on how far along the pregnancy is. For pregnancies up to about 12 to 14 weeks, vacuum aspiration is the standard. This involves using gentle suction to empty the uterus, either with a handheld device or an electric pump. The World Health Organization gives this method its strongest recommendation and advises that older scraping techniques should be replaced by vacuum aspiration wherever they are still used.
After 12 to 14 weeks, the procedure shifts to dilation and evacuation (D&E), which combines cervical preparation, suction, and specialized instruments. The WHO describes D&E as the safest and most effective surgical technique for later abortions when performed by experienced providers. Facilities are encouraged to offer both D&E and medication-based options for later procedures, giving patients and clinicians flexibility.
How It Compares to Medication Abortion
Both surgical and medication abortion are safe, but they differ in completion rates and patient experience. A Cochrane systematic review found that medication methods were roughly two to three times more likely to not complete the abortion compared to vacuum aspiration. When medication abortion is incomplete, a surgical procedure is then needed to finish the process. This doesn’t mean medication abortion is dangerous, but surgical abortion does have a higher single-visit success rate, which some people prefer.
Neither method showed a significant difference in rates of infection or rehospitalization. The choice between the two often comes down to personal preference, gestational age, and what feels right for you. Some people prefer the quicker, more controlled nature of a surgical procedure; others prefer managing the process at home with medication.
Recovery After the Procedure
Recovery from surgical abortion is typically fast. Most people go home the same day, rest, and return to normal activities the following day. If sedation was used during the procedure, you’ll need to avoid driving for 8 to 24 hours depending on the type of medication given.
Bleeding can last up to a week, or come and go for up to four weeks. Cramping usually lasts a few days. Some people experience a distinct episode of heavier bleeding and cramping about four to six days after the procedure, which is normal and resolves on its own. The overall physical recovery is comparable to a heavy period for most people.
Effects on Future Fertility
This is one of the most common concerns, and the evidence is mixed but largely reassuring for single procedures. Some research has identified prior surgical evacuation of the uterus as a potential risk factor for infertility and preterm birth in later pregnancies, while other studies have found it is not an independent risk factor when you account for other variables. The risk, if it exists, appears to be most relevant for people who have had multiple surgical procedures, where repeated dilation and instrumentation could affect the cervix or uterine lining. A single, uncomplicated first-trimester vacuum aspiration carries very low risk to future reproductive capacity.
Mental Health Outcomes
The Turnaway Study, one of the most rigorous longitudinal studies on this topic, followed people over several years and compared those who obtained an abortion with those who were denied one. People who had an abortion did not show an increased risk of depression, anxiety, PTSD, suicidal ideation, or substance use disorders. Those who were denied an abortion, by contrast, initially experienced higher levels of stress, anxiety, and lower self-esteem. The scientific consensus is clear: abortion itself does not cause mental health disorders. Emotional responses afterward vary widely from person to person, ranging from relief to sadness to a mix of both, and all of those responses are normal.
