Question

How do ‘implants’ act as an effective method of contraception in human females?

Answer 1

Implants are small, flexible rods or capsules that are inserted under the skin, usually in the arm, by a healthcare provider. They release hormones (such as progestin) into the bloodstream that work by inhibiting ovulation (the release of eggs from the ovaries).

• Thickening cervical mucus to prevent sperm from reaching the egg.
• Thinning the lining of the uterus to prevent implantation of a fertilized egg.
