What is UFE (Uterine Fibroid Embolization)
Definition & Purpose
- UFE, also called Uterine Artery Embolization (UAE), is a minimally invasive procedure performed by an interventional radiologist. Its goal is to shrink or eliminate uterine fibroids by cutting off or reducing their blood supply.
- It is an alternative to more invasive surgeries like hysterectomy (removal of uterus) or myomectomy (surgical removal of fibroids) when fibroids cause symptoms like heavy bleeding, pelvic pain or pressure, urinary or bowel problems.
Procedure & How It Works
- A catheter is inserted, usually via the groin (femoral artery) or sometimes wrist, under imaging (fluoroscopy) guidance.
- Embolic agents (tiny beads or microspheres) are injected into the uterine arteries feeding the fibroids. These block the blood supply, causing the fibroids to “starve” and shrink over time, relieving symptoms.
- No large incisions; uterus is preserved. Recovery is quicker vs open surgery.
Effectiveness and Outcomes
- Many patients (estimates: ~80-90%) experience significant symptom relief.
- Shrinkage of fibroids is on the order of roughly half (though depends on size, type, and number).
- Some risk: pain/cramping (especially early after procedure), possible temporary effects on ovarian function or fertility. Recurrence of symptoms or need for additional treatments occurs in some.
History / When Introduced
- UFE was first described in 1995 in a small case series of women.
- By the late 1990s it was adopted more broadly in the US and elsewhere. UChicago Medicine notes its first use in the U.S. around 1997.
Who is a Good Candidate / Limitations
- Best if you have symptoms (bleeding, pain, pressure) that affect quality of life.
- If pregnancy in the future is not a priority, or you accept some risk to fertility. UFE may compromise fertility in some cases.
- Not ideal if there is a pelvic infection, certain bleeding disorders, very large or degenerating fibroids, or in some cases fibroids that distort the uterine cavity severely.
Recovery & Aftercare
- The procedure takes about 1 to 3 hours.
- Hospital stay: often outpatient (go home same day) or one night.
- Recovery: mild to moderate discomfort (cramping, pain, possible nausea), usually subsides within days, many resume light activities within a week, full recovery in 1-2 weeks in many cases.
IVF & Its Alternatives: Timeline, Key Milestones, and What Options Exist
Here’s a look at IVF, its history, and other fertility treatments that are or have been alternatives. For each, I’ll include when it emerged / became established, what it involves, and pros & cons (especially relative to IVF).
| Treatment | Established or Major Milestone Date(s) | What It Is / How It Works | Pros & Cons / When Used |
|---|---|---|---|
| In Vitro Fertilization (IVF) | First successful human birth: Louise Brown, England, 1978. First US IVF baby: 1981. |
Eggs are retrieved from a woman, fertilized in a lab with sperm, then embryo(s) transferred into the uterus. Can use own or donor eggs/sperm. Controlled ovarian stimulation is often used to produce multiple eggs. | Pros: high success rates (especially with modern techniques), genetic testing possible, effective for many causes of infertility. Cons: expensive, physically demanding, risk of multiple pregnancies if multiple embryos, risk of ovarian hyperstimulation, emotional burden. |
| Ovulation Induction / Stimulation (e.g., Clomiphene, Letrozole, Gonadotropins) | Mid-20th century: Clomiphene citrate approved in 1960s, use of gonadotropins followed. | Drugs are used to stimulate the ovaries to produce one or more eggs; cycle monitored; sometimes used with timed intercourse or IUI. | Pros: less invasive than IVF, lower cost, fewer risks. Cons: lower success per cycle than IVF; risk of multiples if more than one egg; not effective if severe infertility factors (e.g. blocked tubes, very low sperm count). |
| Intrauterine Insemination (IUI) | Use traces back centuries for artificial insemination; IUI in modern form became more common in 20th century; combined with ovulation induction became well-established mid-20th to late 20th century. | Sperm are prepared in the lab (washed, concentrated) and placed directly into the uterus around ovulation. Can be done in natural cycle or stimulated (medications). | Pros: simpler, cheaper than IVF; less physically burdensome. Cons: lower success rates; less useful if severe female or male factor issues; may require several cycles; risk of multiples with stimulation. |
| Gamete (Egg or Sperm) Donation | Egg donation IVF established in the 1980s; sperm donation earlier but formal egg donation for IVF in ~1984. | When one partner’s gametes are not usable, a donor’s sperm or eggs are used in IVF. | Pros: allows many infertile couples to conceive; donor options broaden choices. Cons: legal, ethical, and emotional considerations; costs; sometimes recipient’s body more likely to reject or have complications. |
| Frozen Embryo / Egg Transfers (Cryopreservation) | First baby from frozen embryo: Australia, 1984; frozen donor egg babies somewhat later. | Eggs or embryos are frozen for later use; allows delaying cycles or saving excess embryos. | Pros: flexibility, reduced ovarian stimulation multiple cycles; preserves fertility. Cons: freeze/thaw reduces viability; may require specific labs and costs; not all frozen eggs/embryos survive. |
| Intracytoplasmic Sperm Injection (ICSI) | First successful pregnancies via ICSI in 1992. | Single sperm is injected directly into oocyte; especially used in male factor infertility (low sperm count or poor motility). | Pros: very helpful for male infertility; large increase in possibilities. Cons: more manipulation; may have slightly different risk profiles; more expensive; ethical concerns in some contexts. |
| Alternative/Less Common ART Techniques (e.g. GIFT, ZIFT, embryo transfer, mitochondrial replacement) | GIFT & ZIFT developed in the 1980s as alternatives to IVF (gametes or zygotes transferred into fallopian tube rather than uterus). Embryo transfer (from one woman to another) first successful in 1983 with birth in 1984. |
These alternatives vary: GIFT = gametes are placed in fallopian tubes; ZIFT = zygote placed in tube; embryo transfer between women, etc. | Pros: sometimes more “natural” in that fertilization or early embryo development occurs in body rather than exclusively in lab. Cons: invasive surgeries in some cases; reduced control; fewer clinics offer them nowadays; often overshadowed by advances in IVF. |
Comparing UFE with Fertility Treatment Options
Since UFE is about treating fibroids whereas IVF and the above options are about assisting fertilization / overcoming barriers to creating a pregnancy, the role of each is different. But sometimes the presence of fibroids is a reason someone considers IVF or other fertility treatments. Key comparison points:
- Purpose: UFE treats fibroids (uterine growths causing symptoms), not directly infertility or fertilization. IVF & alternatives treat infertility or barriers to becoming pregnant.
- Uterus preservation: UFE preserves the uterus (but may impact fertility), whereas some fibroid treatments (myomectomy, hysterectomy) may carry different risks. IVF alternatives often rely on intact reproductive anatomy.
- Fertility outcomes: If fertility is an aim, fibroid treatment strategy matters. Some women with fibroids undergo myomectomy (if fibroids distort uterine cavity), and then may do IVF if needed. UFE's effect on fertility is less certain.
- Invasiveness & recovery: UFE is less invasive than major surgery; many IVF-alternatives (like IUI, ovulation induction) are less invasive but IVF involves egg retrieval (surgery under sedation).
Summary & What to Know
- If fibroids are causing symptoms and interfering with fertility, it’s important to talk with your care team about all options: UFE, myomectomy, possibly combining fibroid treatment with fertility treatment.
- If fertility is a priority, especially desire for pregnancy, then treatment plans should consider not just symptom relief but long-term prospects.
