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...
Exon Recombination02:32

Exon Recombination

The evolution of new genes is critical for speciation. Exon recombination, also known as exon shuffling or domain shuffling, is an important means of new gene formation. It is observed across vertebrates, invertebrates, and in some plants such as potatoes and sunflowers. During exon recombination, exons from the same or different genes recombine and produce new exon-intron combinations, which might evolve into new genes. 
Exon shuffling follows “splice frame rules.” Each exon has three reading...

Summary

Researchers investigated the phosphoglycerate mutase 4 (PGAM4) gene in Chinese men with non-obstructive azoospermia (NOA). No PGAM4 mutations were found, and a specific polymorphism (G75C) was not associated with NOA risk.

Area of Science:

  • Genetics
  • Reproductive Biology
  • Human Health

Background:

  • Non-obstructive azoospermia (NOA) is a severe male infertility cause linked to impaired spermatogenesis.
  • The genetic factors contributing to NOA remain largely unknown, necessitating further research into potential genetic markers.

Purpose of the Study:

  • To investigate mutations and single nucleotide polymorphisms (SNPs) in the phosphoglycerate mutase 4 (PGAM4) gene in Chinese Han men diagnosed with NOA.
  • To determine if PGAM4 gene variations are associated with the susceptibility to NOA in this population.

Main Methods:

  • DNA sequencing of the entire coding region of the PGAM4 gene was performed on 214 participants (103 NOA patients, 111 fertile controls).
  • Polymerase chain reaction (PCR) and DNA sequencing were employed to identify mutations and SNPs within the PGAM4 gene.
  • Genotyping for the G75C (rs138178131) polymorphism was conducted and compared between NOA patients and controls.

Main Results:

  • No disease-causing mutations were detected in the coding region of the PGAM4 gene in either NOA patients or controls.
  • A novel synonymous mutation (G111A, rs20100573) was identified exclusively in control individuals.
  • The frequency of the G75C (rs138178131) polymorphism did not significantly differ between the NOA group and the control group, indicating no association with NOA susceptibility.

Conclusions:

  • Mutations within the coding region of the PGAM4 gene are not a significant cause of non-obstructive azoospermia in the Chinese Han population studied.
  • The G75C polymorphism of the PGAM4 gene is not associated with an increased risk of developing non-obstructive azoospermia in this cohort.
