Birth after testicular sperm extraction and intracytoplasmic sperum injection in non-obstructive azzospermia

摘要

In couples suffering from extreme oligoastheno- teratozoospermia, i.e. impairment in sperum count, motility and morphology, intracytoplasmic sperm injection(ICSI) has been shown to e a highly effective treatment resulting in high fertilisation and pregnancy rates. ICSI provides a new option of assisted reproduction methods to men with no spermatozoa in the ejaculate, i.e. azoospermia. Microsurgical epididymal sperm asipration(MESA)followed By ICSI has resulted in high fertilisation rates in cases of Obstructive azzospermia such as congenital absence of the vas Deferens of failed vasectomy reversal.
