- Which of the following is a permanent sterilization procedure for males?
A. Tubectomy
B. Hysterectomy
C. Vasectomy
D. Laparoscopy
Answer: C. Vasectomy
Explanation: A vasectomy is a permanent sterilization procedure for males in which the vas deferens, the tubes that carry sperm, are cut and sealed. This prevents sperm from entering the semen during ejaculation. Tubectomy is the equivalent procedure for females.
- Which contraceptive method involves tracking ovulation and avoiding intercourse during the fertile window?
A. Oral contraceptive pills
B. Rhythm method
C. Contraceptive implant
D. Copper IUD
Answer: B. Rhythm method
Explanation: The rhythm method is a natural form of contraception that involves tracking the menstrual cycle and avoiding intercourse during the fertile window, when ovulation is likely to occur. It requires careful monitoring and is less effective than other methods.
- Which of the following is the function of human chorionic gonadotropin (hCG) during early pregnancy?
A. Prevents menstruation
B. Stimulates the release of eggs
C. Maintains the corpus luteum
D. Promotes uterine contractions
Answer: C. Maintains the corpus luteum
Explanation: Human chorionic gonadotropin (hCG) is produced by the placenta during early pregnancy and helps maintain the corpus luteum, which produces progesterone necessary to sustain the pregnancy. It prevents menstruation by ensuring the endometrium remains intact.
- Which hormone is primarily responsible for the contraction of the uterus during childbirth?
A. Progesterone
B. Oxytocin
C. Estrogen
D. Prolactin
Answer: B. Oxytocin
Explanation: Oxytocin is the hormone that stimulates uterine contractions during labor and childbirth. It also plays a role in milk ejection during breastfeeding. Progesterone and estrogen are important for maintaining pregnancy, while prolactin is responsible for milk production.
- Which of the following is a method of assisted reproductive technology (ART) where sperm is directly injected into the egg?
A. IVF
B. GIFT
C. ZIFT
D. ICSI
Answer: D. ICSI
Explanation: Intracytoplasmic Sperm Injection (ICSI) is a method of assisted reproductive technology (ART) where a single sperm is directly injected into an egg to facilitate fertilization. This technique is often used in cases of male infertility. IVF (In Vitro Fertilization) is another ART method, but it does not involve directly injecting sperm into the egg.
- What is the function of the contraceptive patch?
A. Prevents ovulation
B. Blocks sperm from entering the uterus
C. Alters the lining of the uterus
D. Stimulates the release of eggs
Answer: A. Prevents ovulation
Explanation: The contraceptive patch is a hormonal method that releases estrogen and progestin to prevent ovulation, similar to oral contraceptive pills. It also thickens cervical mucus to block sperm. It is worn on the skin and changed weekly.
- Which of the following conditions can result from an untreated sexually transmitted infection, potentially leading to infertility in women?
A. Endometriosis
B. Polycystic Ovary Syndrome
C. Pelvic Inflammatory Disease (PID)
D. Menopause
Answer: C. Pelvic Inflammatory Disease (PID)
Explanation: Pelvic Inflammatory Disease (PID) is an infection of the female reproductive organs, often caused by untreated sexually transmitted infections like gonorrhea or chlamydia. It can cause scarring of the fallopian tubes, leading to infertility.
- Which hormone is produced by the placenta during pregnancy and is detected by pregnancy tests?
A. Oxytocin
B. Estrogen
C. Human chorionic gonadotropin (hCG)
D. Progesterone
Answer: C. Human chorionic gonadotropin (hCG)
Explanation: Human chorionic gonadotropin (hCG) is produced by the placenta shortly after implantation and is the hormone detected by home pregnancy tests. It helps maintain the corpus luteum, which produces progesterone during the early stages of pregnancy.
- Which of the following hormones is responsible for maintaining pregnancy by keeping the uterine lining intact?
A. Estrogen
B. Progesterone
C. Oxytocin
D. Luteinizing Hormone (LH)
Answer: B. Progesterone
Explanation: Progesterone is essential for maintaining pregnancy as it helps keep the uterine lining intact, preventing menstruation and ensuring a stable environment for the developing fetus. Estrogen also plays a role in pregnancy but is not as directly responsible for maintaining the uterine lining.
- Which type of assisted reproductive technology (ART) involves placing both eggs and sperm into the fallopian tube for fertilization inside the body?
A. IVF
B. ZIFT
C. GIFT
D. ICSI
Answer: C. GIFT
Explanation: Gamete Intrafallopian Transfer (GIFT) involves placing both eggs and sperm into the fallopian tubes, where fertilization occurs naturally inside the body. This contrasts with IVF, where fertilization occurs outside the body before the embryo is implanted.
