Summary

This summary is machine-generated.

Cell-free DNA (cfDNA) levels in semen are linked to oxidative stress and poor sperm quality in infertile men. Measuring cfDNA and oxidative stress markers may help diagnose male infertility severity and guide antioxidant therapy for improved reproductive outcomes.

Area Of Science

  • Reproductive biology
  • Andrology
  • Biochemistry

Background

  • Male infertility affects a significant portion of couples seeking fertility treatment.
  • Oxidative stress and impaired sperm parameters are recognized contributors to male infertility.
  • Cell-free DNA (cfDNA) in seminal plasma is an emerging biomarker.

Purpose Of The Study

  • To investigate seminal cfDNA levels in infertile men.
  • To explore the relationship between cfDNA, oxidative stress, antioxidant capacity, and lipid peroxidation in seminal plasma.
  • To assess the diagnostic potential of cfDNA and oxidative stress markers in male infertility.

Main Methods

  • Semen samples were collected from 100 infertile men with various sperm abnormalities and normozoospermic controls.
  • cfDNA was extracted and quantified using quantitative polymerase chain reaction (qPCR).
  • Seminal plasma markers of oxidant/antioxidant status and lipid peroxidation were measured.

Main Results

  • Elevated seminal cfDNA was observed in men with oligoasthenoteratozoospermia compared to controls.
  • A significant decrease in cfDNA was noted in the non-obstructive azoospermia group.
  • All patient groups exhibited increased oxidative stress markers (e.g., malondialdehyde) and reduced antioxidant capacity compared to controls.

Conclusions

  • A direct correlation exists between elevated seminal cfDNA, increased oxidative stress, and impaired sperm parameters in infertile men.
  • cfDNA and oxidative stress markers show potential as diagnostic tools for classifying male infertility severity.
  • Antioxidant therapy may improve sperm quality and reproductive outcomes by reducing oxidative damage.

Infertility in Males 01:23

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...

Spermatogenesis 01:41

122.0K

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...

During ejaculation, males release around 2-5 milliliters of semen, which is a complex mixture of mature sperm and various fluids produced by accessory glands. The mature sperm cells measure approximately 60 micrometers in length and consist of a head, neck, midpiece, and tail. The head is flattened and tapered, measuring about 4 to 5 micrometers in length. It contains a nucleus with condensed chromosomes and an acrosome, a cap-like structure filled with enzymes essential for penetrating the...
