For some patients with a zero sperm count (azoospermia), sperm
can often be retrieved directly from the testes using a fine
needle aspiration technique - immature sperm thus retrieved can
then be matured in vitro and injected into the wife's oocytes by
ICSI to achieve a viable pregnancy and livebirth. Patients
can be confident about a 25 - 20% take home baby rate with this
revolutionary method too.
