The intrauterine device (IUD) insertion and removal is a common gynecological procedure primarily used for long-term contraception or specific medical needs. This treatment involves placing the contraceptive device into the uterine cavity, providing a reversible contraceptive effect, or removing it under certain circumstances to restore fertility. The procedure is usually performed on an outpatient basis, taking approximately 5 to 15 minutes, but must be carried out by a qualified physician after evaluating the patient's health status.
The main purpose of an IUD is to provide an effective and long-term method of contraception, with advantages including a success rate of up to 99%, effectiveness lasting from 3 to 10 years, and rapid fertility recovery after removal. Additionally, certain hormonal IUDs can be used to treat conditions such as menorrhagia or endometriosis.
IUDs are divided into copper and hormonal types. Copper IUDs (such as Paragard) inhibit sperm activity and embryo implantation through copper ion release, while hormonal IUDs (such as Mirena, Kyleena) release progestin-like substances that thin the endometrial lining and thicken cervical mucus, preventing sperm penetration.
Their mechanisms primarily involve altering the uterine environment to prevent fertilization or implantation, with immediate effects (copper types require a 5-day waiting period to ensure correct positioning). Hormonal IUDs can also reduce menstrual bleeding and provide various medical benefits.
Suitable for women with stable partners and no congenital uterine abnormalities or infection risks. Some hormonal IUDs are also approved for symptom relief in endometriosis.
Prior to insertion, measurements of uterine size and screening for infections are necessary. The physician will use a dilator to place the IUD at the uterine fundus. The choice of device depends on patient age, uterine condition, and health history; for example, women over 35 who do not smoke may opt for hormonal types, while multiparous women should select appropriately sized devices.
The removal procedure is typically performed in an outpatient setting, using specialized forceps to grasp the IUD string. It is recommended to perform removal during menstruation or when the cervix is more relaxed to reduce the risk of uterine perforation.
Compared to other contraceptive methods, IUDs reduce daily medication burden and do not contain estrogen, making them suitable for breastfeeding women or those with hypertension. Hormonal IUDs can also improve irregular menstrual issues.
Common short-term discomforts include lower abdominal cramping and light bleeding between periods, which usually resolve after a few months. It is important to note that serious complications such as severe infections, uterine perforation, or device displacement are rare but can lead to serious consequences.
Hormonal IUDs may cause intermenstrual bleeding or breast tenderness, while copper IUDs may worsen menstrual flow and dysmenorrhea. Immediate medical attention should be sought if severe abdominal pain or fever occurs.
Prior to insertion, Pap smear and screening for sexually transmitted infections are necessary. If pregnancy is suspected or there is a history of severe thrombosis, the physician may recommend alternative contraceptive methods.
Copper IUDs combined with anticoagulants may increase bleeding risk, while hormonal IUDs with antiepileptic drugs (such as carbamazepine) may reduce efficacy. Concurrent use of IUDs with oral contraceptives does not enhance effectiveness and may increase thrombosis risk.
Patients undergoing radiation therapy or immunosuppressive treatment should discuss risks and alternatives with their healthcare provider.
Clinical studies show that the failure rate of copper IUDs is less than 0.8% annually, and hormonal IUDs can reduce menstrual flow by up to 90%. Long-term follow-up indicates that over 95% of patients regain normal ovulation within six months after removal.
The World Health Organization (WHO) classifies IUDs as a first-line contraceptive method, with efficacy and safety validated through multiple meta-analyses. The benefits of hormonal IUDs in improving menstrual-related symptoms have been published in top journals such as The New England Journal of Medicine.
Oral contraceptives or barrier methods (such as condoms) are options but lack the long-term stability of IUDs. Subdermal implants are convenient but require replacement every three years, while tubal ligation is a permanent option.
The physician will compare the effectiveness and side effect risks of each method based on the patient's age, reproductive plans, and health status, providing personalized recommendations.
What examinations or preparations are needed before placing an intrauterine device (IUD)?
Before IUD placement, it is recommended to perform a Pap smear, screening for uterine infections (such as sexually transmitted infections), and confirm uterine position. The physician may advise avoiding the procedure during menstruation and fasting for 4 hours prior if anesthesia is needed. Additionally, inform the doctor of any history of uterine surgery or allergies to assess suitability.
What should I do if I experience severe abdominal pain or heavy bleeding after IUD placement?
If severe abdominal pain, fever over 38°C, or bleeding exceeding normal menstruation occurs within 24 hours of placement, seek medical attention immediately. These may indicate uterine perforation or infection requiring urgent treatment. Mild discomfort can be managed with prescribed painkillers and observation of symptoms.
Should I avoid lifting heavy objects or vigorous exercise after IUD placement?
It is recommended to avoid lifting objects over 5 kilograms and strenuous activities within 24 to 48 hours post-procedure to reduce the risk of uterine bleeding or device displacement. Normal walking and light activities can generally continue, but specific restrictions should be adjusted based on individual recovery and medical advice.
What is the likelihood of IUD displacement or expulsion after placement? How can I detect abnormalities?
Initial use of IUD has about a 3-5% chance of displacement or expulsion within the first year, most occurring within three months post-procedure. If irregular menstrual intervals, feeling the device tail during intercourse, or persistent lower abdominal discomfort are observed, an ultrasound should be performed to confirm position. Regular follow-up can reduce risks.
If I plan to conceive after IUD removal, how long should I wait before trying to get pregnant?
Fertility can be attempted immediately after IUD removal, with no waiting period. However, if a progestin-containing device (such as a contraceptive rod) was used, some women may need a few weeks to restore normal ovulation cycles. Discuss reproductive plans with your doctor before trying to conceive and ensure no residual device remains in the uterus.
