A 49-year-old man visited the outpatient clinic suffering from painless swelling of the left testicular content which he had recognized 1 week earlier. The lower portion of the testis or the epididymis gave rise to a thumb-head sized irregular tumor. At the exploring operation, the tumor was revealed to be the swollen epididymal tail. Epididymectomy was performed. Microscopically, the tumor was diagnosed as an epididymal granuloma invaded by many sperm, histiocytes, macrophages, neutrophil leukocytes and lymphocytes around the epididymal tubules. Eight cases of epididymal sperm invasion reported in Japan during the recent 20 years are reviewed and briefly discussed.

Although the glycosylation of viral proteins plays a critical role in the process of viral invasion into host cells, studies on the glycosylation of monkeypox virus (MPXV) structural proteins have not yet been reported. To investigate the importance of MPXV protein glycosylation, poly Ser-Arg (poly SR) materials capable of simultaneously enriching both -glycopeptides and -glycopeptides were synthesized by surface-initiated reversible addition-fragmentation chain transfer (SI-RAFT) polymerization. The poly SR materials were evaluated using the digest mixture of standard proteins containing bovine fetuin and bovine serum albumin, and the digest of complex biological samples including bovine sperm tail lysate, mouse sperm tail lysate, mouse brain lysate, and human serum.

Background: Intrauterine insemination (IUI) is an effective and inexpensive method of managing patients with unexplained and male factor infertility. It is attempted before proceeding to more invasive assisted reproductive techniques such as fertilisation and intracytoplasmic sperm injection. Numerous semen parameters have been assessed to indicate successful outcomes with IUI.

Infertility presents multifaceted challenges that encompass both physical and emotional burdens. Yoga, as a comprehensive system of mind-body medicine, serves as an effective intervention for managing male factor infertility, a complex lifestyle disorder with significant psychosomatic elements. This review explores the transformative role of yoga in addressing both the emotional and physical dimensions of infertility.

Background: The Optilume benign prostatic hyperplasia (BPH) catheter system is a novel minimally invasive paclitaxel-coated dilation system that has demonstrated substantial and durable results in urinary flow and symptoms.
Aim: We now assess the impact of Optilume BPH procedure on sexual function.
Methods: Prior published results have described the methods of data collection during the PINNACLE study, which demonstrated durable improvement in urinary symptoms.

Manual semen evaluation methods are subjective and time-consuming. In this study, a deep learning algorithmic framework was designed to enable non-invasive multidimensional morphological analysis of live sperm in motion, improve current clinical sperm morphology testing methods, and significantly contribute to the advancement of assisted reproductive technologies. We improved the FairMOT tracking algorithm by incorporating the distance and angle of the same sperm head movement in adjacent frames, as well as the head target detection frame IOU value, into the cost function of the Hungarian matching algorithm.
