As we previously reported, testes of men suffering from hypospermatogenesis and germ cell arrest or Sertoli cell-only syndrome show a major increase in the number of macrophages expressing interleukin-1β (IL-1β) and abundant expression of cyclooxygenase-2 (COX-2), the inducible isoform of the key enzyme in the biosynthesis of prostaglandins (PGs), in Leydig cells. In the present study we report [1] a positive correlation between IL-1β levels and COX-2 expression in testes of infertile patients, [2] the induction of COX-2 by IL-1β in mouse Leydig cells (TM3) and human macrophages (THP-1), and therefore [3] evidence for an IL-1β-dependent induction of testicular inflammatory states.

Background: To address knowledge gaps, this study aimed to investigate the involvement of inflammasomes in the etiology of azoospermia. This study focused on the gene expression of key inflammasome components, including , and .
Methods: We analyzed gene expression in blood and testicular tissue from patients with obstructive azoospermia (OA) and non-obstructive azoospermia (NOA).

SARS-CoV-2, also called coronavirus causes SARS-CoV-2 or severe acute respir-atory syndrome, a highly transmissible disease that has rapidly spread worldwide, straining healthcare systems and leading to a substantial number of fatalities. Interestingly, SARS-CoV-2 has revealed a gender difference, with males dying at a greater rate and with more severe cases than women. It's worth noting that the male reproductive system might be par-ticularly susceptible to damage during periods of moderate to severe sickness, which has been linked to cases of orchitis and erectile dysfunction.

Spermiogenesis is an indispensable process occurring during the later stages of spermatogenesis. Despite multiple proteins being associated with spermiogenesis, the molecular mechanisms that control spermiogenesis remain poorly characterized. In this study, we show that 1700030J22RIK is exclusively expressed in the testis of mice and investigate its roles in spermiogenesis using genetic and proteomic approaches.

Asthenoteratozoospermia is a common cause of male infertility. To further define the genetic causes underlying asthenoteratozoospermia, we performed whole-exome sequencing in a cohort of Han Chinese men with asthenoteratozoospermia. Homozygous deleterious variants of MYCBPAP were first identified in two unrelated Chinese cases.
