Micromapping testicular sperm extraction: A new technique for microscopic testicular sperm extraction in nonobstructive azoospermia [PDF]

Reproductive Medicine and Biology
Purpose In microscopic testicular sperm extraction (mTESE) for nonobstructive azoospermia (NOA), sperm can be recovered relatively easily in some cases, and mTESE may be retrospectively considered excessive.

Case report: remedial microdissection testicular sperm extraction after onco-microdissection testicular sperm extraction failure. [PDF]

Medicine (Baltimore)
Background: Testicular cancer (TC) mostly occurs in men aged 14 to 44. Studies have shown that TC seriously damages male fertility, and 6% to 24% of patients with TC were even found to suffer from azoospermia when they are diagnosed. At present, some studies have pointed out that onco-microdissection testicular sperm extraction

Pregnancy via Testicular Sperm Extraction for Anejaculation After Neuroblastoma Surgery [PDF]

IJU Case Reports
Background Surgical treatment of a neuroblastoma, a malignant tumor of the sympathetic nervous system, may result in ejaculatory disorder. There are no reports examining ejaculation disorders after neuroblastoma surgery. Case Presentation The patient was

Strategies in Infertile Azoospermic Patients with Negative Microdissection Testicular Sperm Extraction Surgery [PDF]

Urology Research and Practice, 2020
Non-obstructive azoospermia is reported to affect 1 in 100 men, and despite advances in surgical practice, the succesful sperm retrieval rate for microdissection testicular sperm extraction surgery (mTESE) is only 46%.

Rate of testicular histology failure in predicting successful testicular sperm extraction. [PDF]

Front Endocrinol (Lausanne)
BackgroundThe management of Non-Obstructive (NOA) Azoospermia or Obstructive Azoospermia (OA) patients relies on testicular sperm extraction (TESE) followed by intracytoplasmic sperm injection (ICSI). In NOA patients the sperm recovery is successful in only 50% of cases and therefore the ability to predict those patients with a high probability of ...

Re: Comparison of Microdissection Testicular Sperm Extraction, Conventional Testicular Sperm Extraction, and Testicular Sperm Aspiration for Nonobstructive Azoospermia: A Systematic Review and Meta-Analysis

Journal of Urological Surgery, 2016
In contemporary medicine, testicular sperm extraction (TESE) and using testicular sperm for intracytoplasmic injection is the only fertility treatment in men with nonobstructive azoospermia (NOA).

Testicular sperm extraction and intracytoplasmic sperm injection [PDF]

Human Reproduction, 1998
We evaluate the efficacy of testicular sperm extraction and results of intracytoplasmic sperm injection in cases of nonobstructive azoospermia. In addition, we define predictive parameters for successful testicular sperm extraction in these patients.A total of 154 patients with nonobstructive azoospermia underwent multiple testicular biopsies to obtain

Microdissection testicular sperm extraction [PDF]

Translational Andrology and Urology, 2017
Microdissection testicular sperm extraction (microTESE) is considered the gold standard method for surgical sperm retrieval among patients with non-obstructive azoospermia (NOA). In this review, we will discuss the optimal evaluation of NOA patients and strategies to medically optimize NOA patients prior to microTESE.
