BACKGROUND Factor affecting sperm retrieval rate (SRR) or pregnancy rates (PR) after
testicular sperm extraction (TESE) in patients with non-obstructive azoospermia (NOA) have …

When it was initially discovered in 1923, inhibin was characterized as a hypophysiotropic
hormone that acts on pituitary cells to regulate pituitary hormone secretion. Ninety years …

Our objective was to establish which is the best sperm retrieval technique in non-obstructive
azoospermia based on the available evidence. To date, no randomized controlled trial has …

Intracytoplasmic sperm injection (ICSI), combined with surgical sperm retrieval (SR)
techniques, is the sole option for patients with non-obstructive azoospermia to achieve …

The development of intracytoplasmic sperm injection (ICSI) opened a new era in the field of
assisted reproduction and revolutionized the assisted reproductive technology protocols for …

PURPOSE: We developed an artificial neural network and nomogram using readily
available clinical features to model the chance of identifying sperm with microdissection …

Background Testicular sperm extraction (TESE) is an essential therapeutic tool for the
management of male infertility. However, it is an invasive procedure with a success rate up …

Azoospermia in men requires microsurgical reconstruction or a procedure for sperm retrieval
with assisted reproduction to allow fertility. While the chance of successful retrieval of sperm …

BACKGROUND In non-obstructive azoospermia (NOA), testicular sperm extraction (TESE) is
successful in∼ 50% of cases. A parameter for predicting TESE quality and pregnancy rates …

The lack of clinically-reliable biomarkers makes impossible to predict sperm retrieval
outcomes at testicular sperm extraction (TESE) in men with non-obstructive azoospermia …
