For how long does NETEN (Norethisterone enanthate) prevent pregnancy?

Correct option is B

NETEN (Norethisterone enanthate) is a progestogen-based injectable contraceptive that prevents pregnancy for two months (8 weeks) per injection. It is an effective and convenient short-term contraceptive method requiring repeat injections every two months to maintain contraceptive protection.
Explanation of Options:
· (a) One month: Too short; NETEN is effective for longer.
· (b) Two months: Correct answer; a single dose provides protection for 8 weeks.
· (c) Three months: Incorrect; Depot Medroxyprogesterone Acetate (DMPA) is a 3-month contraceptive, not NETEN.
· (d) Four months: No injectable contraceptive is designed for this duration.
