How does lifestyle modification improve male fertility?
- A. By directly increasing sperm motility and morphology.
- B. By reducing stress and improving overall reproductive health.
- C. By guaranteeing successful fertilization.
- D. By eliminating the need for medical treatments.
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.

Which diagnostic test is commonly used to evaluate the structure and patency of the uterus and fallopian tubes?
- A. Semen analysis.
- B. Endometrial biopsy.
- C. Hysterosalpingography.
- D. Testicular biopsy.
Correct Answer: C
Rationale: The correct answer is C: Hysterosalpingography. This test involves injecting a contrast dye into the uterus and fallopian tubes to evaluate their structure and patency. It helps diagnose issues like blockages or abnormalities. Semen analysis (A) is used to evaluate male fertility, not the uterus or fallopian tubes. Endometrial biopsy (B) is used to evaluate the uterine lining, not the structure of the uterus or fallopian tubes. Testicular biopsy (D) is used to assess male reproductive health, not female reproductive structures. Therefore, C is the correct choice for evaluating the structure and patency of the uterus and fallopian tubes.
What is the role of cervical mucus observation in tracking ovulation?
- A. To confirm ovulation has already occurred.
- B. To detect peak fertility by observing changes in mucus consistency.
- C. To determine the overall health of the uterus.
- D. To predict the gender of the future baby.
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).
How does weight management affect fertility in both men and women?
- A. It has no impact on fertility outcomes.
- B. Maintaining a healthy weight improves hormonal balance and sperm quality.
- C. Weight loss is only beneficial for women trying to conceive.
- D. Being underweight enhances fertility in men.
Correct Answer: B
Rationale: The correct answer is B because maintaining a healthy weight positively affects hormonal balance and sperm quality in both men and women, leading to improved fertility outcomes. This is supported by research showing the link between obesity and infertility. Choice A is incorrect as weight management does impact fertility. Choice C is incorrect as weight loss can benefit fertility in both genders. Choice D is incorrect as being underweight can actually negatively impact fertility in men.
Lisa, a 35-year-old practicing attorney and marathon runner, presents to the clinic with a complaint of irregular menses. She tells the nurse, 'My husband and I want to start a family but it hasn't happened yet. We stopped using birth control 6 months ago. Should we be concerned?' What is the nurse's best response?
- A. Relax and it will happen.
- B. No, infertility is the failure to conceive after 1 year of unprotected intercourse.
- C. Aging and extreme exercise regimens may impact fertility. You should address your concerns with your provider during today's visit.
- D. Decreasing your exercise frequency and intensity will increase your chances of conceiving.
Correct Answer: C
Rationale: The correct answer is C because it addresses Lisa's concerns about fertility in a comprehensive and logical manner. Firstly, it acknowledges the potential impact of aging and extreme exercise on fertility, which is important considering Lisa's age and marathon running. Secondly, it emphasizes the importance of discussing her concerns with her healthcare provider during the visit, ensuring a thorough evaluation and appropriate guidance. This response shows understanding of the possible factors contributing to her irregular menses and infertility concerns.
Now, let's analyze the other choices:
A: "Relax and it will happen" is dismissive and lacks medical advice or addressing potential underlying causes of infertility.
B: "No, infertility is the failure to conceive after 1 year of unprotected intercourse" provides a definition of infertility but does not offer practical advice or address Lisa's specific situation.
D: "Decreasing your exercise frequency and intensity will increase your chances of conceiving" assumes exercise is the sole factor affecting fertility and oversimplifies the issue without considering other potential causes.
Of the following karyotype results, which indicates a finding of Turner syndrome?
- A. 46 XY
- B. 46 YY
- C. 46 XX
- D. 46 X
Correct Answer: D
Rationale: Certainly. The correct answer is D (46 X) for Turner syndrome. Turner syndrome is characterized by a missing or partially missing X chromosome in females. Therefore, a karyotype of 45,X or 46,X would indicate Turner syndrome. Choice A (46 XY) is a normal male karyotype, B (46 YY) is not a valid karyotype, and C (46 XX) is a normal female karyotype.
