eEF1G supports translation elongation of meiotic mRNAs in transcriptionally quiescent leptotene and zygotene spermatocytes. Its depletion in germ cells causes meiotic arrest at the zygotene stage, with defective homologous synapsis and unstable recombination intermediates.

D‐limonene supplementation enhances testicular recovery following orchiopexy in a rat model of bilateral cryptorchidism. Treatment with D‐limonene reduces oxidative stress (↓MDA, ↑SOD, ↑GPx, ↑TAC), downregulates pro‐apoptotic proteins (↓TNF‐α, ↓BAX, ↓Caspase‐3), and upregulates anti‐apoptotic Bcl‐2 expression.

Abstract Stenopodidea represents one of the basal lineages within Pleocyemata, yet the male reproductive system (MRS) of this group remains poorly understood, with limited information available regarding its morphology and function. This study provides the first detailed description of the MRS in four stenopodidean shrimp species from two families ...

Redox regulation of mammalian sperm capacitation
Capacitation is a series of morphological and metabolic changes necessary for the spermatozoon to achieve fertilizing ability. One of the earlier happenings during mammalian sperm capacitation is the production of reactive oxygen species (ROS) that will ...

Ursolic Acid Alleviates Orchitis via Modulating Ferroptosis in Peritubular Myoid Cells of Testis
Ursolic acid modulates key ferroptosis‐related pathways in the peritubular myoid cells of the testis in forest musk deer. ABSTRACT Chronic stress adversely affects reproductive health, increasing susceptibility to pathologies such as orchitis. Additionally, the maintenance of iron homeostasis is essential for preserving the function of the testicles ...

The spermatocytic seminoma: views on pathogenesis [PDF]
The spermatocytic seminoma has clinical and histological characteristics which differ from those of other germ cell tumours of the testis. Classical seminomas and teratomas are believed to originate from intratubular carcinoma‐in‐situ (CIS), which is almost invariably found adjacent to these neoplasms. In addition, DNA analysis of these tumours and the

Behavioral mechanisms of mammalian sperm guidance
In mammals, sperm guidance in the oviduct appears essential for successful sperm arrival at the oocyte. Hitherto, three different potential sperm guidance mechanisms have been recognized: thermotaxis, rheotaxis, and chemotaxis, each of them using ...

This study delineates the early sex differentiation timeline in the northern snakehead (Channa argus). These findings provide a foundation for future sex‐control breeding in this economically important species. ABSTRACT The northern snakehead (Channa argus) is an economically important aquaculture species in China.
