Infertility and hypergonadotropic hypogonadism as first evidence of hereditary apolipoprotein A-I amyloidosis [PDF]
, 2007 Purpose: We report that primary infertility and hypergonadotropic hypogonadism in young patients may be caused by testicular amyloidosis and it is associated with the presence of a mutation in the apoA-I gene, resulting in the replacement of proline for ...

Bronchiectasis and oligospermia: two families. [PDF]
Thorax, 1985 Five patients from two families had a bronchiectasis syndrome; the men also had oligospermia with poor progressive sperm motility. None of the patients had cystic fibrosis, alpha 1 antitrypsin deficiency, immunoglobulin deficiency, structural abnormalities of the bronchi, or abnormalities of ciliary ultrastructure.

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

Peroxiredoxin 4 Involved in Spermatogenesis by Affecting Oxidative Stress and Ferroptosis
Andrology, EarlyView.ABSTRACT Background The main functions of testes are sperm production and androgen secretion in testicular befitting microenvironment. Excessive level of the reactive oxygen species (ROS) from metabolism and cellular events can lead to oxidative stress (OS) and ferroptosis, which injure the functions of mitochondria and endoplasmic reticulum (ER) of ...

Chromodomain Helicase DNA–Binding Proteins and Spermatogenesis: Current Advances
Andrology, EarlyView.ABSTRACT Background Male infertility is a prevalent clinical condition, with approximately one‐third of cases classified as idiopathic, frequently stemming from impaired spermatogenesis because of dysregulated gene expression. Chromodomain helicase DNA‐binding (CHD) proteins are central chromatin remodelers that orchestrate this epigenetic regulation ...

Spata19 Inactivation as a Cause of Oligospermia
Research in Molecular Medicine, 2021 Background: Spermatogenesis associated 19 (Spata19) was introduced as a testis-specific gene that was probably involved in spermatogenesis cell apoptosis.
