Open in App
Solution
The correct option is C Transdermal patches
Contraceptives are the agents that allow sexual intercourse but don’t allow pregnancy to occur. They create certain conditions which make it very difficult for the gametes (male and female) to fertilise or the embryo to implant.
A contraceptive can be applied either externally or internally. But, if it acts by releasing chemicals into the bloodstream, it must be a kind of chemical contraceptive. Among the given options, transdermal patches and implants are chemical contraceptives. Transdermal patches are applied to the skin. These are adhesive patches that can be worn on the upper torso (excluding breasts), buttocks, upper outer arm, abdomen. These patches slowly keep releasing their hormones into the bloodstream of the user through the skin.
Implants are hormonal contraceptives inserted surgically under the skin. They are applied internally. They release hormonal preparations into the bloodstream.
Condoms are one of the barrier methods. In males, they are used to cover the copulatory organ externally. It prevents the sperms from being deposited in the female reproductive tract. Though they are applied externally, they don’t release any chemicals into the bloodstream.
Diaphragms are designed specifically for women. These are rubber cap-like structures with metallic rims. They are inserted into the vagina prior to sexual intercourse. They have an internal application.
Hence, we see that both condoms and skin patches have an external application, but only skin patches function by releasing chemicals into the bloodstream.
