When a couple experiencing infertility presents for a fertility workup, which of the following procedures should the nurse prepare the couple to have first?
- A. hysterosalpingography
- B. semen analysis
- C. endometrial biopsy
- D. transvaginal ultrasound
Correct Answer: B
Rationale: Because semen analysis is the least invasive of the tests listed and because in 35% of the cases the infertility is related to a male factor, semen analysis should be one of the first diagnostic tests performed. Hysterosalpingography fills the uterus and fallopian tubes with a radiopaque substance that can be seen with an X ray. It demonstrates tubal patency or any distortion of the uterine cavity. Endometrial biopsy provides information about the effects of progesterone after ovulation and the endometrial receptivity. Transvaginal ultrasound is mostly used in the treatment of infertility. For diagnosis it allows the endocrinologist to evaluate the developing follicle, assess oocyte maturity, and diagnose luteal phase defects. All the tests listed in Choices 1, 3, and 4 are more invasive, require greater expertise to evaluate and treat, and are more costly. If the semen analysis is normal, the couple can expect to progress through these tests as well.
