Serum inhibin B as a marker of spermatogenesis [PDF]

, 1998
Inhibin B is produced by Sertoli cells, provides negative feedback on FSH secretion, and may prove to be an important marker for the functioning of seminiferous tubules.

FSH levels and testicular volumes are associated with the severity of testicular histopathology in men with non-obstructive azoospermia

Journal of Assisted Reproduction and Genetics, 2021
The purpose of this study is to assess a potential association between FSH levels and testicular volumes with the severity of testicular histopathology on testicular biopsy in men with non-obstructive azoospermia (NOA) undergoing microdissection ...

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

TEX11 is mutated in infertile men with azoospermia and regulates genome-wide recombination rates in mouse [PDF]

, 2015
Genome‐wide recombination is essential for genome stability, evolution, and speciation. Mouse Tex11, an X‐linked meiosis‐specific gene, promotes meiotic recombination and chromosomal synapsis.

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.

Loss of Cx43 in Murine Sertoli Cells Leads to Altered Prepubertal Sertoli Cell Maturation and Impairment of the Mitosis-Meiosis Switch. [PDF]

, 2020
Male factor infertility is a problem in today's society but many underlying causes are still unknown. The generation of a conditional Sertoli cell (SC)-specific connexin 43 (Cx43) knockout mouse line (SCCx43KO) has provided a translational model ...

A WHO 2021‐based comprehensive scheme outlining sperm parameters’ associations with IVF outcomes in PGT‐A cycles

Andrology, EarlyView.
Abstract Objective To examine the association between semen parameters, assessed according to World Health Organization (WHO)‐2021 criteria, and paternal body mass index (BMI) and age, with embryological and clinical outcomes in ICSI cycles involving preimplantation genetic testing for aneuploidy (PGT‐A).

Clinical outcomes and development of children born to couples with obstructive and nonobstructive azoospermia undergoing testicular sperm extraction-intracytoplasmic sperm injection: A comparative study

Taiwanese Journal of Obstetrics & Gynecology, 2015
Objective: To evaluate and compare the clinical outcomes and development of children born between obstructive azoospermia (OA) couples and nonobstructive azoospermia couples (NOA) after testicular sperm extraction (TESE) and intracytoplasmic sperm ...

The use of deidentified organ donor testes for research

Andrology, EarlyView.
Abstract Our knowledge of testis development and function mainly comes from research using mammalian model organisms, primarily the mouse. However, there are integral differences between men and other mammalian species regarding cellular composition and expression profiles during fetal and post‐natal testis development and in the mature testis ...
