Aman with benign prostatic hyperplasia is scheduled for a transurethral incision of the prostate (tuip). as he is being admitted to the surgical unit, he tells the nurse he is concerned that the operation will result in impotence. which is the best response by the nurse?

The nurse must answer that the cases of impotence during this operation are exceptional (or rare).

The quality of erections and libido are not usually altered by the intervention. Impotence is exceptional.  However, the risk of retrograde ejaculation is important (90%). This is characterized by the absence of sperm emission at the time of orgasm.  It is secondary to opening of the bladder neck caused by resection of the adenoma. This does not change in principle the feeling of pleasure.

the fossil record provides evidence of a common ancestor to many species.
