Laboratory processing and intracytoplasmic sperm injection using epididymal and testicular spermatozoa: what can be done to improve outcomes?

Clinics
There are two main reasons why sperm may be absent from semen. Obstructive azoospermia is the result of a blockage in the male reproductive tract; in this case, sperm are produced in the testicle but are trapped in the epididymis.

Maternal Consumption of Artificially Sweetened Beverages in Pregnancies and Biomarkers of Fecundity in Adult Sons

Andrology, EarlyView.
ABSTRACT Introduction Maternal intake of artificial sweeteners in beverages (ASB) during pregnancy may have a programming effect on offspring health, including biomarkers of male fecundity. Objective We investigated whether maternal intake of ASB during pregnancy was associated with biomarkers of male fecundity in adult sons.

Diabetes‐Induced Testicular Injury: Potential Protective Roles of Curcumin, Garcinia kola, and Momordica charantia in Rats

Andrology, EarlyView.
ABSTRACT Background Diabetes mellitus (DM) induces multifaceted cellular and structural alterations in the male reproductive system, thereby predisposing to infertility. Objectives This study aimed to evaluate the morphological, stereological, biochemical, histopathological, and ultrastructural changes induced by DM in testicular tissue, and to ...

Obesity Is an Independent Risk Factor for Oligozoospermia, With Co‐Existing Hyperglycemia Exacerbating Risks of Asthenozoospermia and Elevated Sperm DNA Fragmentation

Andrology, EarlyView.
ABSTRACT Background Metabolic health plays a critical role in maintaining male fertility and may influence offspring health. Therefore, it is necessary to incorporate metabolic indicators into the clinical assessment of male fertility. However, the relationships between different metabolic abnormalities and semen quality remain incompletely understood.

Rescue of ICSI failure in non-obstructive azoospermia by switching from cryopreserved to fresh testicular sperm: a paired clinical analysis

Scientific Reports
Non-obstructive azoospermia (NOA) is a severe form of male infertility. Although cryopreserved testicular sperm are widely used for intracytoplasmic sperm injection (ICSI), a subset of patients experience poor outcomes with a specific frozen-thawed ...

Prevalence of Spermatozoa in the Ejaculate of Adolescents With Klinefelter Syndrome: Implications for Fertility Counseling

Andrology, EarlyView.
ABSTRACT Background Klinefelter syndrome (KS) is the most common genetic cause of male infertility and is associated with nonobstructive azoospermia. Advances in surgical sperm retrieval techniques have enabled biological fatherhood in a subset of men with KS.

A Systematic Review on the Presentation and Management of Segmental Testicular Infarction

Andrology, EarlyView.
ABSTRACT Background Segmental testicular infarction (STI) is a rare and likely underdiagnosed cause of acute scrotal pain. Its clinical and imaging presentation often mimics testicular torsion or malignancy, frequently leading to unnecessary surgical intervention.

Children Born Using Ejaculated Sperm From Men With Klinefelter Syndrome. Is Sperm Production Associated With Testicular Volume?

Andrology, EarlyView.
ABSTRACT Background A large number of children have been born using testicular sperm from men with Klinefelter syndrome (KS), whereas reports of children conceived using ejaculated sperm are rare. Objective To review all published cases of children conceived using ejaculated sperm from men with KS, assess their health and karyotype, and evaluate ...

Seminal Biomarkers and Sperm Proteomic Signatures Differentiate Acute and Chronic Male Accessory Gland Inflammation

Andrology, EarlyView.
ABSTRACT Background Male accessory gland inflammation (MAGI) comprises a heterogeneous group of inflammatory conditions that may differentially affect the seminal microenvironment and sperm function. However, whether transrectal ultrasound (TRUS)‐defined MAGI phenotypes correspond to distinct biological profiles remains insufficiently characterized ...
