Liposarcoma of the spermatic cord (LSC) is extremely rare; < 200 cases were reported in the medical literature. Because of the rarity of these tumors and their presentation as a painless inguinal or scrotal mass, preoperative diagnosis is uncertain and they are frequently misdiagnosed as inguinal hernias.

Paclitaxel (PAC), derived from Taxus brevifolia, is used to treat solid tumours but causes reproductive toxicity due to oxidative stress, affecting sperm quality and testicular tissue. Nerolidol (NRL), an antioxidant sesquiterpene alcohol, has not been studied for its potential to reduce PAC-induced reproductive damage. This study investigates NRL's ability to mitigate PAC-induced reproductive toxicity in rats.

Background: DNA methylation plays a crucial role in mammalian development. While methylome changes acquired in the parental genomes are believed to be erased by epigenetic reprogramming, accumulating evidence suggests that methylome changes in sperm caused by environmental factors are involved in the disease phenotypes of the offspring. These findings imply that acquired sperm methylome changes are transferred to the embryo after epigenetic reprogramming.

The study of the mechanism of oligoasthenospermia, which is a major cause of male infertility, has been the focus of research in the field of male reproduction. TAp73, a member of the p53 family of oncogenes, is endowed with tumor-suppressing activity due to its structural and functional homology with p53. It has been found that TAp73, plays a key role in spermatogenesis and maintaining male reproduction.

Aims: Extragonadal yolk sac tumour (YST) is rare, and may present a diagnostic challenge. YST differentiation was recently reported in some somatically derived tumours in the sinonasal location and in the female genital tract, together with a SMARCB1/INI1 loss. We report two paratesticular/inguinal tumours with striking morphological and immunohistochemical similarities with YST, further expanding the spectrum of extragonadal tumours with YST-like morphology and SMARCB1/INI1 loss.
