Advantages

Disadvantages

Abstinence

Effectiveness: 100%

STI Protection: Dependent on which behaviors a person chooses to engage in. Oral, anal and vaginal sex all carry risks for STI transmission.

Hormones: None

  • No cost.
  • No side effects.
  • Most effective method of STI prevention if oral, anal and vaginal sex are all abstained from. To prevent STI transmission, latex condoms and dental dams should be used every time the user decides to engage in oral, anal and vaginal sex, even if penetration does not occur.
  • Can still get sexual pleasure through masturbation.
  • Can focus on alternate activities with your partner.
  • Requires discipline and self-control.
  • May be unprepared for protection against pregnancy or infection if user decides to forego abstinence.
  • Pregnancy can occur from non-coital activities, like dry humping while unclothed. Any activity that allows semen to come into contact with the vaginal opening carries a risk of pregnancy.

Sterilization

Includes: Vasectomy (males) or Tubal Ligation (females) 
 
Effectiveness: 99.5% 

STI Protection: None 

Hormones: None 
 
 
 
 
 
 
 
 
 
 
 
 
 

Male Sterilization (vasectomy):
  • Highly effective and permanent form of contraception.
  • No effects on sexual desire or performance.
  • Ease of surgery. The surgery is performed under general anesthesia and only takes about 30 minutes and the patient can usually return home within the next hour.
  • Sexual activity can resume about a week after surgery.
  • Male sterilization is not immediately effective following surgery; residual sperm may remain in the vas deferens for 3 months after the surgery is performed, which means additional contraception should be used during those 3 months.
  • Has no noticeable effect on the volume of ejaculate since sperm is such a small component of semen.
  • Can be reversed, though reversal procedures can be expensive and high risk.
Female Sterilization (tubal ligation):
  • Is immediately effective following surgery.
  • Highly effective and permanent form of contraception.
  • No effects on sexual desire or performance.
  • Ease of surgery. The surgery is performed under general anesthesia and only takes about 30 minutes and the patient can usually return home within a few hours. Can be performed on patients within 24 hours after childbirth or on outpatients.
  • Associated with a decrease in the risk of ovarian and endometrial cancer.
  • Can be reversed, though reversal procedures can be expensive and high risk.
 
Both:
  • High initial cost.
  • Since they are surgical procedures there is risk of infections at the site of incision. Also, they must be performed under anesthetics.
  • Reversal procedures can be expensive and high risk.
Male Sterilization (vasectomy):
  • Long-term vasectomy complications can include chronic testicular aches that intensify with ejaculation.
  • Vasovasostomy surgery (vasectomy reversal) has only a 50% chance of success.
Female Sterilization (tubal ligation):
  • The surgery for tubal ligation is riskier and more expensive than a vasectomy. Also has a longer recovery period.
  • If tubal ligation fails, there is an increased risk for ectopic pregnancy.
  • Pregnancy following Tubal Ligation reversal surgery has a 40-80% success rate, dependent on factors including a female’s age, amount of scar tissue and type of ligation procedure performed.
