Prognostic factors for sperm retrieval in non-obstructive azoospermia

Clinics, 2013
Testicular sperm retrieval techniques associated with intracytoplasmic sperm injection have changed the field of male infertility treatment and given many azoospermic men the chance to become biological fathers.

Organoids and organ‐on‐a‐chip models for investigating the pathophysiology of the human reproductive system

Interdisciplinary Medicine, EarlyView.
Organoids and organ‐on‐a‐chips are advancing reproductive system research. In the female reproductive system, applications include cancer organoid models, placental chips, and hormone simulation models. For the male reproductive system, research focuses on drug resistance mechanisms, co‐culture platforms, and infertility studies. These refined in vitro

Do partial AZFc deletions affect the sperm retrieval rate in non-mosaic Klinefelter patients undergoing microdissection testicular sperm extraction?

BMC Urology, 2020
Background The purpose of this study is to evaluate the prognostic factors for sperm retrieval and determine if Y chromosome deletion is associated with deleterious effects on spermatogenesis in non-mosaic Klinefelter patients.

The Application Value of Transvaginal Three‐Dimensional Ultrasonography in the Diagnosis of Adenomyosis of the Uterus

Journal of Clinical Ultrasound, EarlyView.
In this study, 3D‐TVS measurements of the uterine junction zone (JZ) in 120 patients showed that a JZmax threshold of ≥ 0.45 cm yielded 77% sensitivity and 89% specificity for adenomyosis diagnosis. Notably, JZ thickness varies minimally with age, demonstrating its stability and excellent diagnostic performance.

Bisexual releases are as effective as male‐only releases to control Drosophila suzukii with the sterile insect technique

Pest Management Science, EarlyView.
Bisexual releases are as effective as male‐only releases to control Drosophila suzukii with the sterile insect technique. Releasing sterile Drosophila suzukii males or males and females in cages led to the same degree of induced sterility in wild females.

Can Testicular Size Be a Predictive Factor for Successful Sperm Retrieval in Patients with Non Obstructive Azoospermia?

Gynecology Obstetrics & Reproductive Medicine, 2019
Objective: Non-obstructive azoospermia, defined as absence of spermatozoa in the ejaculate caused by impaired spermatogenesis, is the most severe cause of male infertility.

Sperm cryopreservation protocol for micro-TESE-retrieved sperm

Asian Journal of Andrology
Abstract Azoospermia is characterized by the absence of sperm in the ejaculate and is categorized into obstructive azoospermia (OA) and nonobstructive azoospermia (NOA). For men with NOA, testicular sperm extraction (TESE) is the only method to obtain sperm for assisted reproductive technology (ART).
