Implant

Through implants, the progestogens are delivered into general circulation in a slow and sustained release manner with lesser side effects. Once implanted, they release drug slowly over a period of 1-5 years depending upon which kind of implant is used.

Implants may be biodegradable or non-biodegradable. Non-biodegradable implants need removal after drug delivery period is over.

Advantages

• Long-acting with sustained effect
• Does not affect sexual intercourse timing
• Return of fertility is prompt (within 4-12 weeks)
• Reduced systemic side effects

Disadvantages  

• Breakthrough bleeding and irregular cycles
• Ectopic pregnancy reported in 1.3% cases
• Local infection at the site of insertion may occur
• Implants are expensive
• Requires insertion and removal with non-biodegradable implants  (even though it is just a minor surgical procedure)
• Infertility may be seen in a few cases after the removal of the implant
