Take-home Messages
Routine semen analysis not a good male fertility discriminator.
Sperm DNA damage provides information of great prognostic value.
Antioxidants helpful to decrease oxidative stress and DNA damage.
Specific medical therapy only valid for hypogonadism.
Microsurgical varicocele repair increases chances of spontaneous
and assisted conception.
Sperm retrieval is routinely used in ART.
Reproductive potential of surgically-retrieved sperm depends on
type of azoospermia..
