Spermatogenesis and sertoli cell activity in mice lacking Sertoli cell receptors for follicle stimulating hormone and androgen [PDF]

open access: yes, 2008
Spermatogenesis in the adult male depends on the action of FSH and androgen. Ablation of either hormone has deleterious effects on Sertoli cell function and the progression of germ cells through spermatogenesis.

Testicular expression of TDRD1, TDRD5, TDRD9 and TDRD12 in azoospermia. [PDF]

open access: yes, 2020
BACKGROUND: Tudor domain-containing proteins (TDRDs) play a critical role in piRNA biogenesis and germ cell development. piRNAs, small regulatory RNAs, act by silencing of transposons during germline development and it has recently been shown in animal ...

Thyroid hormone receptors and ligand, tissue distribution and sexual behavior [PDF]

open access: yes, 2018
The thyroid hormones (THs) triiodothyronine (T3) and tetraiodothyronine, or thyroxine (T4), not only dramatically impact on development and differentiation, but also on the sexual and reproductive function.

Action of the Metalloproteinases in Gonadal Remodeling during Sex Reversal in the Sequential Hermaphroditism of the Teleostei Fish Synbranchus marmoratus (Synbranchiformes: Synbranchidae) [PDF]

open access: yes, 2018
Teleostei present great plasticity regarding sex change. During sex reversal, the whole gonadincluding the germinal epithelium undergoes significant changes, remodeling, and neoformation.However, there is no information on the changes that occur within ...

A Unique Cytoplasmic Marker for Extratesticular Sertoli Cells

open access: yesCell Transplantation, 2002
In the absence of a definitive cell marker for testis-derived Sertoli cells, their identification in cell culture or in Sertoli cell-facilitated cell transplantation protocols is difficult and limits the creditable evaluation of experimental results ...
