Comparative efficacy of varicocelectomy and intrauterine insemination in varicocoele patients with mild semen abnormalities: An observational study

Andrology, EarlyView.
Abstract Background Varicocoele is a common cause of male infertility, affecting spermatogenesis through increased testicular temperature, venous stasis, and oxidative stress. Microsurgical subinguinal varicocelectomy improves semen quality, whereas intrauterine insemination is widely used for mild male factor infertility.

RNF187 Facilitates Proliferation and Migration of Human Spermatogonial Stem Cells Through WDR77 Polyubiquitination

Cell Proliferation, EarlyView.
RNF187 mediates the polyubiquitination and subsequent degradation of WDR77, reduces H4R3me2s catalysed by the WDR77/PRMT5 complex, and derepresses the transcription of EGR1, thereby promoting the proliferation and migration of human SSCs. ABSTRACT The E3 ubiquitin ligase RNF187, also known as RING domain AP1 coactivator‐1, is a member of the RING ...
