The effect of hexachlorocyclohexane (HCH) treatment in male albino rats at dosages of 3 and 6 mg/kg body weight by force-feeding were studied over a period of 180 days. Histological observations revealed graded degeneration in the muscular layer of vas deferens. Moreover, the accumulation of HCH residue in serum and vas deferens is highly significant in the experimental group. The contractility of muscles showed marked inhibition by in vitro study.

Role of lipid binding protein, Niemann pick type C-2, in enhancing shrimp sperm physiological function.

Sperm activation occurring in both male and female reproductive tract involves a highly complex series of biomolecular dynamics, particularly on membrane lipids and proteins. In mammals, the universal anticipation in cholesterol (CHO) sequestration plays a role in mammalian sperm maturation/capacitation, subsequently enhancing sperm fertilizing ability. In shrimp, we have previously shown that the level of cholesterol (CHO) is significantly reduced in vas deferens sperm when compared with sperm in the testes, presumably due to the sequestering action of the lipid-binding protein, one of which is Niemann-Pick Type C-2 (NPC2).

Background: 6-Nitrodopamine (6-ND) released from rat vas deferens acts an endogenous modulator of vas deferens contractility.
Objectives: To investigate whether rat isolated seminal vesicles (RISV) releases 6-ND, the mechanisms involved in the release, and the modulatory role of 6-ND on tissue contractility.
Methods: Rat seminal vesicles were removed and placed in Krebs-Henseleit's solution at 37°C for 30 min, and an aliquot was used to analyze the concentrations of 6-ND, dopamine, noradrenaline, and adrenaline by liquid chromatography with tandem mass spectrometry (LC-MS/MS).
Leptin action on ARC-PVN neural circuit regulates ejaculation behavior by altering sympathetic neuroplasticity.

January 2025
Department of Urology, The First Affiliated Hospital of Nanjing Medical University, Nanjing, China.
Background: Although some studies have revealed the close relationship between leptin and premature ejaculation in clinical practice, whether and how leptin participates in the regulation of ejaculatory behaviors are still unknown.
Objective: To explore the role of leptin on ejaculatory behaviors and its underlying mechanism.
Materials And Methods: Copulation behavior tests were performed after acute and chronic leptin administration at peripheral and central levels.
Anatomical recognition of dissection layers, nerves, vas deferens, and microvessels using artificial intelligence during transabdominal preperitoneal inguinal hernia repair.

Department of Surgery, Tsudanuma Central General Hospital, 1- 9-17 Yatsu, Narashino, Japan.
Purpose: In laparoscopic inguinal hernia surgery, proper recognition of loose connective tissue, nerves, vas deferens, and microvessels is important to prevent postoperative complications, such as recurrence, pain, sexual dysfunction, and bleeding. EUREKA (Anaut Inc., Tokyo, Japan) is a system that uses artificial intelligence (AI) for anatomical recognition.

Duplication of the vas deferens is a rare congenital anomaly, with an incidence of ~0.05% in the general population. It is typically discovered incidentally during surgeries involving the spermatic cord, such as inguinal hernia repair.
