Can Hormonal Therapy Improve the Outcomes of mTESE in Patients With Non‐Obstructive Azoospermia?

open access: yesAndrology, EarlyView.
ABSTRACT Background Non‐obstructive azoospermia (NOA) represents the most severe form of male infertility. Hypogonadism is common in NOA patients, and normal testosterone (T) levels are considered essential for spermatogenesis. Fertility‐preserving hormonal therapy (FpHT) has been proposed to optimize hormonal milieu and improve sperm retrieval rates ...

Microdissection testicular sperm extraction: effect of prior biopsy on success of sperm retrieval [PDF]

open access: yes, 2007
We determined the effect of prior biopsies with no sperm seen on the chance of sperm retrieval with microdissection testicular sperm extraction in men with nonobstructive azoospermia. A total of 311 men with NOA underwent microdissection testicular sperm

Testicular Biopsies in Adolescent and Adult Andrological Patients: The EAA Clinical Guidelines

open access: yesAndrology, EarlyView.
ABSTRACT Background Histological evaluation of testicular tissue is central to the assessment of infertile men, particularly those at an increased risk of testicular germ cell tumors (TGCT). Traditionally, testicular biopsies have been used primarily for diagnostic purposes, such as the detection of germ cell neoplasia in situ (GCNIS). With advances in

Testicular fine-needle aspiration versus testicular open biopsy: Comparable sperm retrieval rate in selected patients [PDF]

open access: yes, 2012
Background: Sperm recovery by testicular fine-needle aspiration (TESA) has resulted in variable sperm retrieval rate (SRR) and is generally considered inferior to open biopsy (testicular sperm extraction [TESE]).

Adenosine—A Regulator of Human Testicular Peritubular Cells

open access: yesAndrology, EarlyView.
ABSTRACT Background Extracellular purines, in particular ATP and adenosine, are regulators of physiological and pathophysiological processes throughout the human body. Roles in the human testis are emerging and include actions on peritubular cells, which form the wall of seminiferous tubules.
