Genomic technologies and the diagnosis of 46, XY differences of sex development

Andrology, EarlyView.
Abstract Differences/disorders of sex development can be caused by disruptions to the molecular and cellular mechanisms that control development and sex determination of the reproductive organs with 1:100 live births affected. Multiple genes are associated with 46, XY differences/disorders of sex development that can cause varying clinical phenotypes ...

Phenotype and gene signature of testicular tumors in 129.MOLF‐Chr19 mice resemble human teratomas

Andrology, EarlyView.
Abstract Background Testicular germ cell tumor (TGCT) is the most common type of tumor in young men. Type II germ cell tumors including postpubertal‐type teratomas are derived from the germ cell neoplasia in situ (GCNIS), whereas prepubertal‐type teratomas arise independently of the GCNIS.

How exome sequencing improves the diagnostics and management of men with non‐syndromic infertility

Andrology, EarlyView.
Abstract Male infertility affects approximately 17% of all men and represents a complex disorder in which not only semen parameters such as sperm motility, morphology, and number of sperm are highly variable, but also testicular phenotypes range from normal spermatogenesis to complete absence of germ cells.

Phenotypic continuum and poor intracytoplasmic sperm injection intracytoplasmic sperm injection prognosis in patients harboring HENMT1 variants

Andrology, EarlyView.
Abstract Background Small RNAs interacting with PIWI (piRNAs) play a crucial role in regulating transposable elements and translation during spermatogenesis and are essential in male germ cell development. Disruptions in the piRNA pathway typically lead to severe spermatogenic defects and thus male infertility. The HENMT1 gene is a key player in piRNAs

Innovative all‐in‐one exome sequencing strategy for diagnostic genetic testing in male infertility: Validation and 10‐month experience

Andrology, EarlyView.
Abstract Background Current guidelines indicate that patients with extreme oligozoospermia or azoospermia should be tested for chromosomal imbalances, azoospermia factor (AZF) deletions and/or CFTR variants. For other sperm abnormalities, no genetic diagnostics are recommended.

Rapid detection of mouse spermatogenic defects by testicular cellular composition analysis via enhanced deep learning model

Andrology, EarlyView.
Abstract Background Histological analysis of the testicular sections is paramount in infertility research but tedious and often requires months of training and practice. Objectives Establish an expeditious histopathological analysis of mutant mice testicular sections stained with commonly available hematoxylin and eosin (H&E) via enhanced deep learning

Imatinib decreases germ cell survival and germline stem cell proliferation in rodent testis ex vivo and in vitro

Andrology, EarlyView.
Abstract Background Imatinib and dasatinib are tyrosine kinase inhibitors (TKIs) increasingly used to treat several diseases in both children and adults at fertile age. We have previously shown that imatinib has adverse effects on developing testis, and imatinib‐treated male patients have been reported to have reduced sperm counts.

EP300‐interacting inhibitor of differentiation 3 is required for spermatogenesis in mice

Andrology, EarlyView.
Abstract Background Mammalian spermatogenesis is a highly complex process of cell proliferation, meiosis, and differentiation. A series of genes are expressed in an orderly and precise manner to ensure spermatogenesis, with chromatin undergoing intricate changes throughout.

Testicular histopathology and its association with germ cell numbers, serum concentrations of reproductive hormones, and semen quality

Andrology, EarlyView.
Abstract Background It is well‐established that spermatogenesis, semen quality, and reproductive hormones are interlinked. It is, however, less well‐described how various specific testicular histopathologies are linked to reproductive hormones and semen quality.
