Genes located in Y-chromosomal regions important for male fertility show altered transcript levels in cryptorchidism and respond to curative hormone treatment

open access: yesBasic and Clinical Andrology, 2019
Résumé Contexte La non descente des testicules chez les garçons cryptorchides qui présentent une mini-puberté défectueuse et un taux réduit de testostérone (T) ont des gonocytes incapables de se différencier normalement en spermatogonie Ad.

Novas perspectivas no diagnóstico do hipogonadismo pediátrico masculino: a importância do AMH como marcador de células de Sertoli [PDF]

open access: yes, 2011
Sertoli cells are the most active cell population in the testis during infancy and childhood. In these periods of life, hypogonadism can only be evidenced without stimulation tests, if Sertoli cell function is assessed.

On the descent of the epididymo-testicular unit, cryptorchidism, and prevention of infertility

open access: yesBasic and Clinical Andrology, 2017
Résumé Cette revue complète traite en profondeur les progrès réalisés dans la compréhension des mécanismes moléculaires à la base de la cryptorchidie, une pathologie fréquente décrite pour la première fois aux environs de 1786 par John Hunter.

Investigation of the Protective Effects of Amlodipine on the Structure and Function of Testicular Tissue following Experimental Unilateral Cryptorchidism in Rats [PDF]

open access: yesIranian Journal of Veterinary Surgery, 2019
Objective- Cryptorchidism, common birth defect of the male genital tract, is one of the causes of fertility problems. The elevation of tissue temperature following of cryptorchidism could induce oxidative stress which influences the cellular and tissue ...

Exposure to polychlorinated biphenyls and hexachlorobenzene, semen quality and testicular cancer risk [PDF]

open access: yes, 2015
PURPOSE: We carried out a case-control study to investigate the possible role of occupational and environmental exposure to endocrine disruptors in the onset of testicular cancer (TC). METHODS: We evaluated 125 TC patients and 103 controls.

Occurrence of testicular microlithiasis in androgen insensitive hypogonadal mice [PDF]

open access: yes, 2009
<b>Background</b>: Testicular microliths are calcifications found within the seminiferous tubules. In humans, testicular microlithiasis (TM) has an unknown etiology but may be significantly associated with testicular germ cell tumors ...

Curative GnRHa treatment has an unexpected repressive effect on Sertoli cell specific genes

open access: yesBasic and Clinical Andrology, 2018
Résumé Contexte L’hormone folliculostimulante et la testostérone stimulent les cellules de Sertoli pour soutenir la fonction et la différentiation des cellules germinales. Pendant la minipuberté, lorsque la gonadotrophine (GnRH) stimule les augmentations

Epigenetics, cryptorchidism, and infertility

open access: yesBasic and Clinical Andrology, 2023
Background Cryptorchid boys with defective mini-puberty and impaired differentiation of Ad spermatogonia (high infertility risk) have altered expression of several genes encoding histone methyltransferases compared to patients with intact differentiation

Genomic copy number variation association study in Caucasian patients with nonsyndromic cryptorchidism [PDF]

open access: yes, 2016
Copy number variation (CNV) is a potential contributing factor to many genetic diseases. Here we investigated the potential association of CNV with nonsyndromic cryptorchidism, the most common male congenital genitourinary defect, in a Caucasian ...

Phenotype-specific association of the TGFBR3 locus with nonsyndromic cryptorchidism [PDF]

open access: yes, 2015
PURPOSE: Based on a genome-wide association study of testicular dysgenesis syndrome showing a possible association with TGFBR3, we analyzed data from a larger, phenotypically restricted cryptorchidism population for potential replication of this signal.
