Testicular volume is a noninvasive predictor of sperm retrieval failure in idiopathic nonobstructive azoospermia [PDF]

Asian Journal of Andrology
We investigated the prognostic importance of noninvasive factors in predicting sperm retrieval failure in idiopathic nonobstructive azoospermia (iNOA). We studied 193 patients with nonobstructive azoospermia who underwent microsurgical testicular sperm ...

Surgical Sperm Retrieval Techniques for Assisted Reproductive Technology

Düzce Tıp Fakültesi Dergisi, 2022
Intracytoplasmic sperm injection provides in vitro fertilization for many infertility conditions. It is also an important treatment option for fertilization in azoospermic men. Sperm production in azoospermic male testicles is possible. In these patients,

Seminal extracellular vesicle sncRNA sequencing reveals altered miRNA/isomiR profiles as sperm retrieval biomarkers for azoospermia

Andrology, 2023
Non‐invasive molecular biomarkers for classifying azoospermia by origin into either obstructive or non‐obstructive/secretory azoospermia, as well as for inferring the spermatogenic reserve of the testis of non‐obstructive/secretory azoospermia patients ...

Development of a predictive model for increasing sperm retrieval success by microdissection testicular sperm extraction in patients with nonobstructive azoospermia

Asian Journal of Andrology, 2023
Microdissection testicular sperm extraction (micro-TESE) is widely used to treat nonobstructive azoospermia. However, a good prediction model is required to anticipate a successful sperm retrieval rate before performing micro-TESE.

Endocrine Tests and/or Testicular Volume are Not Predictive of Successful Sperm Retrieval by Conventional Multiple Testicular Sperm Extraction in Nonobstructive Azoospermia

Fertility & Reproduction, 2020
Objectives: This study aimed to determine the role of presurgical markers in the prediction of sperm retrieval by conventional Multiple Testicular Sperm Extraction in infertile Vietnamese men with nonobstructive azoospermia (NOA).

Inhibin B-to-Anti-Mullerian Hormone Ratio as Noninvasive Predictors of Positive Sperm Retrieval in Idiopathic Non-Obstructive Azoospermia

Journal of Clinical Medicine, 2023
Background: The lack of clinically useful biomarkers for predicting micro-TESE outcomes in males with idiopathic NOA. To find clinically reliable serum reproductive hormone markers to predict the outcome of sperm retrieval in men with idiopathic NOA ...

Cryptozoospermia: Should we use ejaculated sperm or surgically retrieved sperm for assisted reproductive technology?

Reproductive Medicine and Biology, 2023
Purpose In cryptozoospermic subjects, it may often may be difficult to secure motile sperm for assisted reproductive technology (ART). We examined the results of ART with frozen thawed ejaculated sperm in cryptozoospermic subjects and evaluated whether ...

Testicular Sperm Extraction Techniques in Subfertile Males

Nepalese Medical Journal, 2020
Introduction: Assisted conception is an option for subfertile couples. Surgical sperm retrieval by testicular sperm aspiration and testicular sperm extraction are widely used safe techniques to yield sperm for intracytoplasmic sperm injection. Experience

AI Model Developed Using Machine Learning for Predicting Sperm Retrieval in Micro-TESE for Nonobstructive Azoospermia Patients

Andrologia, 2023
Azoospermia is a severe problem that prevents couples from having their own children through natural pregnancy. In nonobstructive azoospermia (NOA), microdissection testicular sperm extraction (micro-TESE) is required to collect sperm and, at 40%–60 ...

A systemic review and meta‐analysis exploring the predictors of sperm retrieval in patients with non‐obstructive azoospermia and chromosomal abnormalities

Andrologia, 2021
To identify the most prevalent chromosomal abnormalities in patients with non‐obstructive azoospermia (NOA), consolidate their surgical sperm retrieval (SSR) rates and determine the significant predictors of positive SSR in this patient population.
