Micro-dissection testicular sperm extraction as an alternative for sperm acquisition in the most difficult cases of Azoospermia: Technique and preliminary results in India

Journal of Human Reproductive Sciences, 2013
Context: Non-obstructive azoospermia (NOA) is an unfavorable prognostic condition for male infertility since spermatogenesis is disrupted. Sperm retrieval (SR) coupled with intracytoplasmic sperm injection (ICSI) is the only option for men with NOA who ...

Predicting Micro‐TESE among Heterogeneous Nonobstructive Azoospermic Patients: The Impact on Surgical Decision and ICSI

Andrologia, 2023
Background. Previously published predictive models for microdissection testicular sperm extraction (micro‐TESE) were generally assumed patients with nonobstructive azoospermia (NOA) a homogenous population, i.e., the laboratory predictors were associated with sperm retrieval rate (SRR) in a similar way among different subpopulations.

Adenosine—A Regulator of Human Testicular Peritubular Cells

Andrology, 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.
