How does lifestyle modification improve male fertility?

Correct Answer: B

Rationale: The correct answer is B because lifestyle modifications such as reducing stress, maintaining a healthy weight, avoiding harmful substances, and exercising can improve male fertility by optimizing overall reproductive health. Stress reduction can positively impact hormone levels and sperm production. Choices A, C, and D are incorrect because lifestyle modifications do not directly guarantee successful fertilization, eliminate the need for medical treatments, or directly improve sperm motility and morphology.

Correct Answer: B

Rationale: The correct answer is B: AMH levels indicate ovarian reserve and egg quantity. This is because Anti-Müllerian Hormone (AMH) is primarily secreted by the ovaries and its levels in the blood reflect the number of remaining follicles in the ovaries, which correlates with ovarian reserve and egg quantity. This information is vital for assessing a woman's fertility potential, especially in the context of fertility treatments such as in vitro fertilization (IVF). Choice A is incorrect as AMH testing does not predict the exact time of ovulation, it assesses ovarian reserve. Choice C is incorrect as AMH testing is not used to confirm pregnancy success after IVF, but rather to determine the likelihood of successful response to ovarian stimulation. Choice D is incorrect as AMH does not determine sperm quality in male partners, as it is a hormone produced by the ovaries and is not related to male reproductive function.

Correct Answer: A

Rationale: The correct answer is A: Limit exposure to high temperatures, such as saunas. High temperatures can negatively impact sperm production and quality by affecting the testes' ability to regulate temperature. Saunas, hot tubs, and hot baths can increase scrotal temperature, leading to decreased sperm count and motility. This recommendation is appropriate as it addresses a known lifestyle factor that can affect male fertility. Summary of why other choices are incorrect: B: Increasing calorie intake does not necessarily boost sperm production. A balanced diet is important for overall health, but excessive calorie intake may lead to obesity, which can negatively impact fertility. C: Using over-the-counter supplements may not always improve sperm quality, and some supplements may have negative effects. It's essential to consult a healthcare provider before taking any supplements. D: Avoiding physical activity is not recommended as moderate exercise is beneficial for overall health and can support sperm production. Physical activity helps maintain a healthy weight, which is important for fertility.

Correct Answer: B

Rationale: The correct answer is B: To detect peak fertility by observing changes in mucus consistency. Cervical mucus observation is used to identify the most fertile period during a woman's menstrual cycle. This method helps in predicting ovulation by tracking changes in mucus consistency, which indicates the best time for conception. Other choices are incorrect because cervical mucus observation does not confirm ovulation has already occurred (A), determine the overall health of the uterus (C), or predict the gender of the future baby (D).

Correct Answer: B

Rationale: The correct answer is B, to assist fertilization by injecting a single sperm directly into an egg. In ICSI, a single sperm is carefully selected and injected into an egg to aid fertilization, particularly in cases of male infertility. This method ensures that fertilization occurs successfully by bypassing natural barriers. Choice A is incorrect as multiple sperm fertilizing an egg can lead to genetic abnormalities. Choice C is incorrect as ovulation is induced before egg retrieval, not during stimulation cycles. Choice D is incorrect as ovarian stimulation is necessary to produce multiple eggs for retrieval.
