Insights

Hepatitis B virus (HBV) infection in infertile men is linked to poorer sperm DNA integrity, showing abnormal sperm nuclear maturity compared to fertile men. This indicates HBV infection further impairs sperm DNA quality in infertile individuals.

Area of Science:

  • Reproductive Biology
  • Virology
  • Genetics

Context:

  • Male infertility affects a significant portion of the population.
  • Hepatitis B virus (HBV) infection is a global health concern.
  • Sperm DNA integrity is crucial for male fertility and successful reproduction.

Purpose:

  • To investigate the impact of Hepatitis B virus (HBV) infection on sperm DNA integrity in infertile males.
  • To compare sperm DNA integrity between infertile men with and without HBV infection, and with fertile controls.

Summary:

  • This study assessed sperm DNA integrity using DNA fragmentation index (DFI) and high DNA stainability (HDS) via sperm chromatin structure assay (SCSA) in three groups: infertile men with HBV (n=90), infertile men without HBV (n=82), and fertile men (n=70).
  • Results showed significantly higher DFI in infertile groups (A and B) compared to fertile controls (C).
  • Group A exhibited higher HDS than groups B and C, indicating impaired sperm nuclear maturity in HBV-infected infertile males.

Impact:

  • Findings highlight that male infertility is associated with compromised sperm DNA integrity.
  • Hepatitis B virus infection exacerbates sperm DNA damage in infertile men, impacting nuclear maturity.
  • This research contributes to understanding the reproductive health implications of HBV infection in males.

Infertility in Males01:23

Infertility in Males

Male infertility affects millions of couples worldwide, arising from various factors that impact different stages of the reproductive process. An endocrine imbalance resulting from conditions like hypogonadism, Klinefelter syndrome, or pituitary disorders can disrupt hormone levels and reduce sperm production. Testicular defects, such as tumors, cryptorchidism, atrophic testes, abnormal sperm morphology, and low sperm count or motility, may arise due to genetic factors, structural...

Hepatitis

Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...
Spermatogenesis01:41

Spermatogenesis

Spermatogenesis is the process by which haploid sperm cells are produced in the male testes. It starts with stem cells located close to the outer rim of seminiferous tubules. These spermatogonial stem cells divide asymmetrically to give rise to additional stem cells (meaning that these structures “self-renew”), as well as sperm progenitors, called spermatocytes. Importantly, this method of asymmetric mitotic division maintains a population of spermatogonial stem cells in the male reproductive...
Viral Hepatitis I: Introduction01:28

Viral Hepatitis I: Introduction

Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...
