What is the primary function of GnRH agonists in fertility treatments?
- A. To induce ovulation immediately.
- B. To suppress natural hormone production and control the cycle.
- C. To enhance the uterine lining for implantation.
- D. To increase sperm motility in male partners.
Correct Answer: B
Rationale: The correct answer is B: To suppress natural hormone production and control the cycle. GnRH agonists work by initially stimulating the release of certain hormones that eventually lead to the suppression of natural hormone production. This helps to control the menstrual cycle and prevent premature ovulation. Other choices are incorrect because A is typically achieved through other medications, C is more related to other fertility treatments like IVF, and D is not a primary function of GnRH agonists.
