What is the purpose of endometrial biopsy in fertility evaluations?

Correct Answer: B

Rationale: The correct answer is B: To assess the receptivity of the uterine lining for implantation. Endometrial biopsy is performed to evaluate the quality of the uterine lining and its ability to support embryo implantation. By examining the endometrial tissue, doctors can assess factors such as thickness, pattern, and receptivity, crucial for successful implantation and pregnancy. Incorrect choices: A: To determine ovarian reserve and egg quality - Endometrial biopsy does not provide information on ovarian reserve or egg quality. C: To measure hormone levels in the bloodstream - Endometrial biopsy does not measure hormone levels in the bloodstream; instead, it focuses on the uterine lining. D: To monitor embryo development after IVF - Endometrial biopsy is not used to monitor embryo development; it is primarily for assessing uterine receptivity.

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.

Correct Answer: B

Rationale: The correct answer is B because progesterone supplementation helps maintain the uterine lining, which is crucial for implantation and early pregnancy success. Progesterone prepares the endometrium for embryo implantation by thickening the uterine lining and promoting blood flow. This ensures a supportive environment for the developing embryo. The other choices are incorrect as progesterone does not directly trigger ovulation (A), reduce hormonal fluctuations in male partners (C), or eliminate the need for ovarian stimulation (D) in fertility treatments.
