Answer: C. Contraceptive implant

Explanation: The contraceptive implant is one of the most effective reversible methods of birth control, with a failure rate of less than 1%. It works by releasing hormones that prevent ovulation. Oral contraceptive pills and condoms are also effective but have higher failure rates due to user error.

    A. Uterus
    B. Cervix
    C. Fallopian tube
    D. Ovary

    A. Tubectomy
    B. Vasectomy
    C. Hysterectomy
    D. Laparoscopy

    A. Diaphragm
    B. Condom
    C. Intrauterine device (IUD)
    D. Oral contraceptive pills

Answer: C. Intrauterine device (IUD)

Explanation: An Intrauterine device (IUD) is a small T-shaped device that is inserted into the uterus to prevent pregnancy. There are two types of IUDs: copper IUDs, which are non-hormonal, and hormonal IUDs, which release hormones to prevent pregnancy.

  1. Which hormone is responsible for preparing the uterus for pregnancy by thickening the uterine lining?
    A. Oxytocin
    B. Estrogen
    C. Progesterone
    D. Follicle-Stimulating Hormone (FSH)

Answer: C. Progesterone

Explanation: Progesterone is responsible for preparing the uterus for pregnancy by thickening the endometrial lining. This provides a suitable environment for the fertilized egg to implant and develop into an embryo.

  1. Which of the following is a function of the hormone prolactin?
    A. Stimulates uterine contractions
    B. Stimulates milk production
    C. Regulates the menstrual cycle
