Answer
The new contraceptive drug for men offers both advantages and disadvantages in comparison to existing methods:
Advantages
It is a non-permanent method, requiring only one injection, which can be less invasive than surgical options.
It provides long-term protection for up to 13 years, reducing the need for regular contraceptive measures.
Disadvantages
It does not provide protection against sexually transmitted diseases, unlike barrier methods such as condoms.
There may be unforeseen side effects due to the new nature of the drug, which could affect its reliability or acceptance among users.
Lack of reversible options may deter some individuals who want flexibility in their reproductive choices.
In conclusion, while the new drug has clear benefits in terms of convenience and duration, its lack of protection against STDs and potential side effects are significant concerns that must be addressed.
