What is the role of hCG in early pregnancy tests?

Correct Answer: B

Rationale: The correct answer is B because hCG (human chorionic gonadotropin) levels rise after implantation of the fertilized egg in the uterus, confirming pregnancy. This hormone is produced by the developing placenta and is the key marker used in early pregnancy tests to detect pregnancy. A is incorrect because hCG does not stimulate ovulation; rather, it is produced after ovulation to support pregnancy. C is incorrect because while hCG plays a role in supporting pregnancy, it does not directly reduce the risk of miscarriage. D is incorrect because hCG does not suppress the menstrual cycle; it is actually produced during pregnancy and is essential for maintaining the pregnancy.

Correct Answer: B

Rationale: The correct answer is B: SET reduces the risk of multiple pregnancies and associated complications. This is because transferring a single embryo in IVF lowers the chances of multiple gestations, which can lead to higher risks for both the mother and the babies. This choice emphasizes the importance of safety and health benefits for both the mother and potential offspring. Choice A is incorrect as there is no guarantee of a successful pregnancy with one attempt. Choice C is incorrect as ovarian stimulation may still be needed in future cycles even with SET. Choice D is incorrect as SET does not directly improve egg quality for future cycles.

Correct Answer: B

Rationale: The correct answer is B because maintaining a healthy weight and reducing alcohol and caffeine intake can positively impact fertility treatment success rates. Excessive weight, alcohol, and caffeine consumption can negatively affect fertility. Avoiding exercise entirely (choice A) can lead to decreased overall health. Consuming a high-protein diet (choice C) may not be suitable for everyone and may not directly impact fertility. Focusing only on the male partner's health (choice D) neglects the importance of both partners' health in fertility outcomes.

Correct Answer: A

Rationale: The correct answer is A: Cryopreservation of eggs or embryos is an effective option before starting treatment. This is because fertility preservation should ideally be done before cancer treatment to maximize the chances of success. Freezing eggs or embryos before treatment can help preserve fertility potential. B: Fertility preservation after cancer treatment may not be as successful due to the potential damage caused by the treatment. C: Fertility preservation does not guarantee future pregnancy success as it depends on various factors including the patient's age and overall health. D: Sperm banking is not the only available preservation method. Egg or embryo cryopreservation is also an option for female patients.

Correct Answer: B

Rationale: The correct answer is B. Embryo freezing in fertility treatments allows for the storage of embryos for future use, preserving fertility options. This is important in case the initial IVF cycle is unsuccessful or if the individual wants to have more children later on. Freezing embryos also enables individuals to avoid repeated egg retrieval cycles, saving time, cost, and potential risks associated with the procedure. Additionally, it allows for the preservation of younger and healthier embryos, optimizing the chances of successful pregnancy in the future. The other choices are incorrect because they do not align with the primary purpose of embryo freezing in fertility treatments, which is to provide individuals with the option to use stored embryos in the future.
