Cryptorchidism: Novel genetic insights into CCDC149 mutations

Andrology, Volume 14, Issue 5, Page 1155-1163, July 2026.
Abstract Background Cryptorchidism, characterized by the failure of one or both testes to descend into the scrotum, is a common congenital condition that can lead to infertility and increased risk of testicular cancer.

Pubertal development and hypothalamic–pituitary–gonadal axis are altered in male mice lacking Mecp2

Journal of Neuroendocrinology, Volume 38, Issue 7, July 2026.
Abstract Mutations in the MECP2 gene, encoding the epigenetic reader Methyl‐CpG binding protein 2, are the main cause of Rett syndrome, a rare neurodevelopmental disorder. Besides severe symptoms such as profound intellectual disability, loss of speech and motor skills, and epilepsy, loss of function of MECP2 has been associated with pubertal ...

Less calcium in cremaster muscles of boys with undescended testis supports a deficiency in sympathetic innervation [PDF]

, 2002
In addition to an increase in contractility, contracted fibers and small and electron-dense mitochondria have suggested an increase of cytosolic Ca2+ within the cremaster muscles (CM) associated with undescended testis.
