Secondary azoospermia after vasovasostomy
Fertility and Sterility, 2004To determine the frequency of secondary azoospermia after microsurgical vasovasostomy and to determine what factors increase the risk of its occurrence.We performed a retrospective review of three surgeons' experience. Patency was defined as the presence of sperm in at least one postoperative semen sample.

Controversies in the management of nonobstructive azoospermia
Fertility and Sterility, 2009The 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, 1995SummaryBACKGROUND 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

Endocrine studies of azoospermia, II. Serum steroid levels in obstructive azoospermia
Archives of Andrology, 1979Serum estrone, estradiol, estriol, progesterone, 17 alpha-hydroxyprogesterone, and testosterone were determined in the sera of 25 normal males and 25 patients with obstructive azoospermia. An increase in testosterone and estriol levels, and a decrease in other hormones were demonstrated in patients with obstructive azoospermia.

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 ...
