Question

Contraceptive oral pills help in birth control process by

• A. Preventing ovulation
• B. Killing the ova
• C. Killing the sperms
• D. Forming barriers between sperms and ova

Answer 1

The correct option is A Preventing ovulation

• Fertilization of the ovum and its subsequent implantation is referred to as conception or pregnancy. Prevention of conception is called contraception.
• Oral contraceptives (birth control pills) can be taken to change the hormonal balance of the body so that the ovum is not released from the ovary.
• The pills may contain combinations of the hormones estrogen and progestins or progestins alone.
• Combinations of estrogen and progestins prevent pregnancy by inhibiting the release of the hormones luteinizing hormone (LH) and follicle-stimulating hormone (FSH) from the pituitary gland, which further prevents ovulation.

Thus, the correct answer is option A.
