Should cryopreserved epididymal or testicular sperm be recovered from obstructive azoospermic men for ICSI?
Cryopreserved epididymal and testicular sperm, from men with obstructive azoospermia, appear equally effective in ICSI. Epididymal recovery should remain the method of first choice for obstructive azoospermic men but further study of sperm DNA damage rates in different testicular sites is required.
There was no evidence, in humans, of substantial streaming during slow infraophthalmic intracarotid injections. Slow rates of infusion are as good as high rates for infraophthalmic intracarotid drug delivery. This is of special importance for drugs that are not tolerated at high injection rates. Moreover, infraophthalmic intracarotid chemotherapeutic infusion does not require special injectors or catheters.
