Controversies in the management of nonobstructive azoospermia

Fertility and Sterility, 2009
The fertility potential of patients with nonobstructive azoospermia (NOA) depends on sperm extraction from the tissue sample and then in vitro fertilization with intracytoplasmic sperm injection (IVF/ICSI). Unfortunately, there is no consensus regarding predictors that can identify nonobstructive azoospermic men with a potentially high yield at the ...

Diagnostic and clinical features in azoospermia

Clinical Endocrinology, 1995
SummaryBACKGROUND AND OBJECTIVE The recent advances In assisted fertilization and gamete micromanipulation techniques have enabled fertilization in some forms of azoospermia; for example, epididymal sperm aspiration in obstructive azoospermia. Therefore knowledge of the specific degree of testicular damage is of primary importance, since other clinical

Varicocele and Azoospermia

2015
Varicocele is found in 5 % of men with NOA, but its absolute impact on the azoospermic status is still unknown. The advent of assisted reproductive technologies (ART), particularly intracytoplasmic sperm injection (ICSI), has reintroduced the awareness about varicocele with NOA, as improvement in testicular function to obtain viable sperm for ART may ...
