Question

Oral contraceptives prevent ovulation by inhibiting the secretion of

• A. Follicle stimulating hormone
• B. Lutenizing hormone
• C. Progesterone hormone
• D. Both (a) and (b)

The correct option is D Both (a) and (b)

Oral contraceptives contain progesterone that inhibits luteinizing hormone and estrogen that inhibits follicle stimulating hormone. Combined oral contraceptives suppress ovulation and so if there is no egg then there will be no fertilization.
