What is the primary purpose of a semen analysis in an infertility evaluation?

Correct Answer: A

Rationale: The primary purpose of a semen analysis in an infertility evaluation is to assess sperm count, motility, and morphology. This is crucial as these factors directly impact male fertility. Sperm count indicates the quantity of sperm present, motility relates to their ability to move effectively towards the egg, and morphology assesses the shape and structure of sperm, which can affect their ability to fertilize an egg. Evaluating these parameters helps identify potential issues causing infertility. Other choices are incorrect as semen analysis primarily focuses on assessing sperm quality, not infections, hormone levels, or genetic anomalies in sperm.

Correct Answer: B

Rationale: The correct answer is B: BBT is used to confirm ovulation after it occurs. BBT tracking helps confirm ovulation by observing a slight increase in temperature after ovulation. It does not predict ovulation accurately. Choice A is incorrect because BBT is not the most accurate method for predicting ovulation. Choice C is incorrect as BBT tracking can be effective in women of all ages. Choice D is incorrect as BBT tracking is just one method and may not replace other fertility tests.

Correct Answer: B

Rationale: The correct answer is B: Reduce stress levels through relaxation techniques. Stress can negatively impact fertility by disrupting hormone levels and ovulation. Relaxation techniques can help manage stress, promoting better reproductive health. A: Avoiding moderate alcohol consumption is important for fertility, but stress reduction has a more direct impact. C: While protein is essential for overall health, there is no direct evidence linking increased protein intake to improved egg quality. D: Using over-the-counter fertility supplements may not be necessary if stress reduction can improve fertility outcomes without additional interventions.

Correct Answer: B

Rationale: The correct answer is B because progesterone plays a crucial role in maintaining the uterine lining to support implantation and prevent menstrual shedding. Progesterone prepares the uterus for the potential implantation of a fertilized egg by thickening the endometrium. If fertilization occurs, progesterone continues to support the pregnancy by ensuring the uterine lining remains intact to provide a nurturing environment for the developing embryo. Choices A, C, and D are incorrect because progesterone's main function in early pregnancy is not to increase fetal growth rates, stimulate ovulation, or regulate the release of other reproductive hormones.

Correct Answer: A

Rationale: The correct answer is A because cryopreservation allows embryos, eggs, or sperm to be stored for future use, preserving fertility options for patients undergoing fertility treatments. This helps in cases like preserving fertility before undergoing treatments that may affect fertility or for those who wish to postpone childbearing. Choice B is incorrect because cryopreservation doesn't directly improve natural conception rates. Choice C is incorrect as cryopreservation doesn't reduce the need for fertility medications but rather provides a method to store reproductive materials. Choice D is incorrect as cryopreservation doesn't eliminate genetic abnormalities in embryos; it preserves them for potential future use.
