Among 8500 patients attending the fertility clinic due to infertility, 565 men (6.65%) reported an incidence of inguinal hernioplasty with or without subsequent atrophy of the testis. Semen quality (sperm concentrations, motility, and morphology) of these patients was markedly reduced in comparison to that of fertile men. In cases where hernioplasty was followed by atrophy of the testis, damage to sperm characteristics and Sertoli cell function was found to be far greater. This was also reflected in significant serum follicle stimulating hormone elevation (P less than 0.0025). No changes in luteinizing hormone and testosterone were found. No correlation was found between age of hernioplasty and semen quality following operation. The reasons for testicular damage may be due to ischaemic orchitis or immunological reactions.

Vitamin D protects spermatogonia and Sertoli cells from heat stress damage by inhibiting NLRP3.

Introduction: Cryptorchidism can damage cells in the cryptorchid testes due to elevated local temperatures, potentially impacting the fertility of the child in adulthood. Research indicates that vitamin D enhances sperm quality in adult males. This study aimed to explore whether vitamin D inhibits NLRP3 activation, thus helping to mitigate heat stress damage to testicular spermatogenic and Sertoli cells.

Hypospadias is a common congenital malformation of the reproductive system; however, to date, no cases of hypospadias complicated by polyorchidism have been reported in the literature. This article reports a case of a 1-year-old boy presenting with hypospadias, who was also diagnosed with polyorchidism combined with cryptorchidism. Preoperative Doppler ultrasound revealed two testes on the right side, and an atrophic testis on the left.

Multi-tissue characterization of the constitutive heterochromatin proteome in Drosophila identifies a link between satellite DNA organization and transposon repression.

Noncoding satellite DNA repeats are abundant at the pericentromeric heterochromatin of eukaryotic chromosomes. During interphase, sequence-specific DNA-binding proteins cluster these repeats from multiple chromosomes into nuclear foci known as chromocenters. Despite the pivotal role of chromocenters in cellular processes like genome encapsulation and gene repression, the associated proteins remain incompletely characterized.
