Answer
The new contraceptive drug for men offers several advantages compared to existing methods.
Convenience: As it is administered as a single injection, it eliminates the need for daily compliance associated with methods like pills.
Long-lasting: The effectiveness of up to 13 years provides long-term contraception without constant attention.
However, there are notable disadvantages:
Lack of STI protection: Unlike barrier methods (e.g., condoms), this drug does not offer protection against sexually transmitted infections (STIs).
Unknown side effects: As a new drug, potential side effects and long-term health impacts are not fully studied.
In conclusion, while the drug presents significant advantages in terms of convenience and effectiveness duration, considerations around health safety and STI protection must be carefully evaluated.
