0!1 2 – Sperm Retrieval Techniques

he following techni&ues can be used to retrieve sperm in men withnonobstructive azoospermia:

a) 34/A (percutaneous epididymal sperm aspiration)

b) 0icro#4/4 (microdissection testicular sperm e%traction)

c) 4/A (testicular sperm aspiration)

d) !onventional 4/4 (testicular sperm e%traction) using single ormultiple biopsies


3/4


he following statements apply to sperm retrieval techni&ues:

a) 0icro#4/4 yields higher sperm retrieval success rates thanconventional 4/4 or 4/A

b) 34/A is a fast" effective and safe method to retrieve sperm in

obstructive azoospermia 4%pertise in microsurgery is re&uired for34/A

c) 4/A is safe and effective in cases of failed 34/A $o e%pertise inmicrosurgery is re&uired for 4/A

d) 04/A is indicated in obstructive azoospermia /perm retrieval ratesare comparable to 34/A although higher sperm number is obtained


4/4


Overall" sperm retrieval success and pregnancy rates by .!/. (usingretrieved sperm) in men with obstructive (OA) and nonobstructive($OA) azoospermia are:

a) 7+, and 5+," 8+, and 27," respectively

b) 9+, and 6+," 7+#;+, and 27," respectively

c) 7+, and 5+," respectively" and rates are not dependent on the typeof azoospermia being obstructive or nonobstructive

d) *++, and 7+, in OA men with vasectomy" and +, in $OA men with

testicular histology showing germ cell aplasia (/ertoli cell#only)
