Parental Educational Attainment at Birth and Biomarkers of Male Fecundity: A Study From the Danish National Birth Cohort

open access: yesAndrology, EarlyView.
ABSTRACT Background Low parental education is associated with poorer offspring health, but its influence on male fecundity remains unclear. Objective To study the association between parental educational attainment at birth and biomarkers of male fecundity in young men and to explore whether this association is mediated by maternal smoking in pregnancy

Semen Cryopreservation in Testicular Cancer: Before or After Orchidectomy?

open access: yesAndrology, EarlyView.
ABSTRACT Background Fertility preservation in patients with testicular cancer remains a clinical priority, yet the optimal timing for sperm cryopreservation—before or after orchidectomy—remains a matter of debate. Objectives The aim of this study was to determine the optimal timing for semen cryopreservation and the best‐quality sample for ART.

Thyroid Hormones and Testicular Function

open access: yes, 2008
Os hormônios tireoidianos são essenciais para o crescimento, desenvolvimento e metabolismo. O pró-hormônio tiroxina (T4) é sintetizado e secretado pela glândula tireóide junto com uma pequena quantidade do hormônio ativo, a triiodotironina (T3). A conversão de T4 em T3 ocorre na periferia através da atividade das iodotironinas desiodases tipo 1 e tipo ...

Trends in Semen Quality: A Contrasting Perspective From a Single‐Centre Review in Ireland

open access: yesAndrology, EarlyView.
ABSTRACT Introduction Male factor contributes up to half of infertility cases and reports of a global decline in semen quality raise concern for the future of male reproductive health. However, fertility trends can vary by region and population. Interpreting local patterns is crucial for understanding the true trajectory of male fertility.

Testicular SIRT1 Loss Reveals an Aging‐Like Proteomic Landscape and Precipitates Reproductive Deterioration

open access: yesAndrology, EarlyView.
ABSTRACT Background Advanced paternal age is associated with reduced male fertility and testicular dysfunction. Among the molecular regulators involved in aging, SIRT1, a NAD+‐dependent deacetylase, plays a pivotal role in maintaining oxidative balance and cellular homeostasis.

Impact of Chemotherapy on Sperm Functional Characteristics in Patients With Testicular Germ Cell Tumours

open access: yesAndrology, EarlyView.
ABSTRACT Background Testicular germ cell tumours (TGCT) are the most common malignancies among young men and represent a major threat to reproductive health. Both the disease itself and oncological treatments, particularly chemotherapy, can compromise spermatogenesis and semen quality.

Nut Consumption and Sperm Quality in Healthy Men: Results From the Led‐Fertyl Study

open access: yesAndrology, EarlyView.
ABSTRACT Background Nuts are rich in antioxidants and other bioactive compounds, and recent evidence suggests that their regular consumption may be associated with sperm quality. However, the current scientific evidence remains limited and inconsistent.

In Situ Expression of miR‐371a‐3p and miR‐373‐3p in Testicular Germ Cell Tumours and Detection in Serum

open access: yesAndrology, EarlyView.
ABSTRACT Background Testicular germ cell tumours (TGCTs) are the most common type of tumour diagnosed in young men, and reliable non‐invasive biomarkers are crucial for clinical management. MicroRNAs (miRNAs) from the miR‐371–373 cluster have recently been identified as novel and more sensitive serum biomarkers than the conventional protein‐based ...

Incidence of Gonadal and Extragonadal Germ Cell Tumours in Patients With Klinefelter Syndrome

open access: yesAndrology, EarlyView.
ABSTRACT Background Klinefelter's syndrome (KS; 47, XXY) is associated with an altered risk profile for malignancies compared with non‐KS males. In particular, several reports have noted a striking association between KS and extragonadal germ cell tumours (EGCTs), especially in the mediastinum, whereas the risk of testicular germ cell tumours (TGCTs ...
