15. Genetic testing with karyotype and Y-chromosome microdeletion is indicated for all patients with azoospermia or severe oligospermia Genetic abnormalities are rare in men with infertility; however, 10% to 15% of azoospermic men will have a karyotypeabnormality In addition, 10% to 15% of men with azoospermia or severe oligospermia may have microdeletions of the Y-chromosome in addition CFTR mutations are found in 80% of men with CBAVD.

17. 6) Which of the following is TRUE regarding ejaculatory duct obstruction (EJDO)?   a    Normal volume azoospermia is a common presentation for EJDO b    EJDO will often present with low-volume azoospermia   c    Seminal vesicle width greater than 12 to 15 mm is suggestive of obstruction   d    In a patient with suspected EJDO, seminal pH will usually be around 8   e    If any sperm is found in seminal vesicle aspiration at the time of transrectalultrasonography (TRUS), the diagnosis of EJDO is confirmed

18. EJDO will often present with low-volume azoospermia, with an acidic pH usually reflecting only prostatic secretions Occasional sperm may be present in seminal vesicles on men without EJDO, but findings of 3 or more sperm/HPF in the seminal vesicle usually indicate EJDO

19. 7) In the evaluation for vasectomy reversal, which clinical finding is suggestive of epididymal obstruction?   a    Varicocele   b    Hydrocele   c    Sperm granuloma   d    Normal serum follicle-stimulating hormone (FSH) level   e    Vasal gap larger than 2 cm

20. 7) In the evaluation for vasectomy reversal, which clinical finding is suggestive of epididymal obstruction?   a    Varicocele  b    Hydrocele   c    Sperm granuloma   d    Normal serum follicle-stimulating hormone (FSH) level   e    Vasal gap larger than 2 cm

21. The presence of a hydrocele in the presence of excurrentductal system obstruction is often associated with secondary epididymalobstruction Surgeons attempting reconstruction should be aware of the possibility of the need for a vasoepididymostomy

22. 8) In which of the following scenarios is a testis biopsy least helpful?   a    Failure to retrieve motile sperm from the epididymis   b    Sperm retrieval for nonobstructiveazoospermia   c    Diagnostic evaluation of men with congenital absence of vas and normal FSH levels   d    Diagnostic evaluation in azoospermic men with normal findings on scrotal examination and normal serum testosterone and FSH levels   e    Sperm retrieval for men diagnosed with Sertoli cell–only pattern in the testes

24.  Diagnostic evaluation of men with congenital absence of vas and normal FSH levels Testis biopsy is indicated in azoospermic men with testes of normal size and consistency, palpable vasadeferentia, and normal serum FSH levels Under these circumstances, biopsy will distinguish obstructive azoospermia from primary seminiferous tubular failure In the testes of men with congenital absence of vasa, biopsy always reveals normal or at least some spermatogenesis and biopsy is not necessary before definitive sperm aspiration and in-vitro fertilization (IVF) with ICSI

25. 9) All of the following situations are appropriate for assisted reproduction with ICSI as a first line of treatment EXCEPT:   a    obstruction with multiple failures of reconstruction   b    mild oligoasthenospermia with varicoceles and a female partner of 29 years of age   c    Klinefeltersyndrome   d    only a few viable sperm found in the ejaculate   e    postchemotherapyazoospermia

26. 9) All of the following situations are appropriate for assisted reproduction with ICSI as a first line of treatment EXCEPT:   a    obstruction with multiple failures of reconstruction   b    mild oligoasthenospermia with varicoceles and a female partner of 29 years of age   c    Klinefeltersyndrome   d    only a few viable sperm found in the ejaculate   e    postchemotherapyazoospermia

27. Mild oligoasthenospermia with varicoceles and a female partner of 29 years of age Assisted reproduction can be offered to men with surgically unreconstructable obstruction such as congenital absence of the vas deferens; men with few viable sperm in the ejaculate; azoospermic men with varicoceles (half of these men will respond to varicocelectomy with return of enough sperm to ejaculate to achieve pregnancy using IVF with ICSI); and men with nonobstructiveazoospermia.

28. 10) In which of the following scenarios would a diagnostic testicular biopsy provide valuable clinical information?   a    Men with azoospermia, atrophic testes, and an FSH level of 25 IU/L   b    Men with a 47 XXY karyotype   c    Men with a fecundity history who seek vasectomy reversal   d    Men with primary infertility, azoospermia, normal physical examination findings, and a normal serum FSH level   e    Men with anejaculation caused by high spinal cord injury
