Female Sterilization: An Operation to Permanently Prevent Pregnancy. The Fallopian Tubes are Blocked Or Sealed to Prevent The Eggs Reaching the Sperm & Becoming Fertilized.
Benefits (Pros):
- More Than 99% Effective at Preventing Pregnancy.
- Does Not Interrupt The Sexual Life or Sex Drive.
- Does Not affect Hormone Levels & Periods.
Risks (Cons):
- Not Immediately Effective & Need Use of Contraception Until The Operation & Until The Next Period Or for 3 Months After The Operation (Depending on The Type of Sterilization).
- Small Risk of Complications, Such as Internal Bleeding, Infection Or Damage to Other Organs.
- Small Risk of Failure (1:200). This May Increase The Risk of Ectopic Pregnancy.
- High Incidence of Regret, Especially If Done in Young age <30 Years With No Children.
- Sterilization Reversal Is Very Difficult & Not Usually Available On the NHS.
- Sterilization Does Not Protect Against STIs, So You May Need to Use Condoms as well.
The Procedure
- This is a Fairly Minor Operation & One Day Case Surgery.
- It Can be Done On the NHS In Most areas, But Waiting Lists Can be Long.
- Can be Done Either Under General or Local Anaesthesia Depending On The Method Used.
- Contraception Use Until The Operation Day & Right Up Until Your Next Period after Surgery.
- Pregnancy Test On The Surgery Day to rule out Pregnancy.
- Sterilization Can be Performed At Any Stage in the Menstrual cycle.
Surgical Methods for Female Sterilization
- A Laparoscopy is Usually Used Because It’s Faster & With Rapid Recovery. (Failure Rate 2-5:1000)
- Mini-Laparotomy May be Recommended for Women Who:
- Have had Recent Abdominal or Pelvic Surgery
- Are Obese
- Have a History of Pelvic Inflammatory Disease
- The Surgeon Will Block The Fallopian Tubes by Either:
- Applying Clips: Plastic or Titanium Clamps are Closed Over the Fallopian Tubes (Failure Rate 3:1000)
- Applying Rings: A Small Loop of the Fallopian Tube is Pulled Through a Silicone Ring, Then Clamped Shut
- Tying, Cutting and Removing a Small Piece of the Fallopian Tube
- Complete Removal of The Tube (Salpingectomy) has a Protective Effect On Ovarian Cancer
Alternatives (LARC) (Reversible & More Effective)
1. IUCD (Copper Coil)
- A Small Plastic & Copper Device
- Acts by:
- Prevents the Sperm from Surviving
- Alters the Cervical Mucus & Endometrial Lining to Prevent Sperm from Reaching The Ovum
- Prevents Implantation of the Fertilized Egg
- It Can be Uncomfortable or Painful & Can be Offered Under Local Anesthetic to Prevent Fits
- Failure Rate: 6:1000 (>99% Effective)
- Works for 5 or 10 Years
- Periods May be Heavier, Longer or More Painful
- Fertility returns as soon as it is removed
2. IUS (Mirena)
- T-shaped Plastic Device, Which Releases the Hormone Progestogen
- Acts by:
- Thinning The Endometrium
- Thickening The Cervical Mucus
- Failure Rate: 2:1000
- Works for 5 Years
- Periods Become Lighter, Shorter & Often Less Painful
- Fertility returns as soon as it is removed
3. Injectable Contraception (Depo-Provera)
- IM Injection Given Every 3 Months
- Releases The Hormone Progestogen Which:
- Prevents Ovulation
- Thickens the Cervical Mucus
- Thins the Endometrium
- Failure Rate: 2:1000
- May Delay Return of Fertility by Up to 1 Year
- Periods May Stop, Be Irregular or Longer
- Suitable for Epileptic Patients On Enzyme Inducers
4. Progestogen Only Subdermal Implants
- Most Effective Method (Failure Rate: 5:10000)
- Not Suitable for Women on Enzyme Inducers like Carbamazepine
5. Male Sterilization (Vasectomy)
- Failure Rate: 1 in 2000
- Less Risk, Done Under Local Anaesthesia
- Not an Option in This Case
Additional Precautions
- IUCD & IUS Should be Inserted in a Hospital Setting with Local Anesthetic and Precautions
- No Contraindication for IUCD in Women With History of Ectopic Pregnancy
