Abstract

Insights

Mitochondrial abnormalities are common in idiopathic asthenospermia, impacting sperm function. Reduced mitochondrial function and ultrastructure damage correlate with decreased sperm viability.

Area of Science:

  • Reproductive Biology
  • Cell Biology
  • Biochemistry

Context:

  • Idiopathic asthenospermia is a leading cause of male infertility.
  • Mitochondria are crucial for sperm motility and energy production.
  • The role of mitochondrial dysfunction in asthenospermia requires further elucidation.

Purpose:

  • To investigate the ultrastructure and function of mitochondria in patients with idiopathic asthenospermia.
  • To correlate mitochondrial changes with sperm activity and viability.

Summary:

  • Sperm samples from 151 idiopathic asthenospermia patients and 53 controls were analyzed.
  • Mitochondrial ultrastructure was examined using transmission electron microscopy.
  • Levels of succinate dehydrogenase (SDH) and mitochondrial membrane potential (MMP) were measured, alongside the incidence of mitochondrial pathological changes (MPCs).

Impact:

  • Findings reveal a significant association between mitochondrial ultrastructure, function, and sperm viability in idiopathic asthenospermia.
  • This study highlights mitochondrial dysfunction as a key factor in male infertility.
  • Understanding these mechanisms may lead to novel diagnostic and therapeutic strategies for asthenospermia.

Mitochondria01:37

Mitochondria

Mitochondria are eukaryotic cellular organelles that are known to produce energy through a process called oxidative phosphorylation. Besides their primary function, mitochondria are involved in various cellular processes, including cell growth, differentiation, signaling, metabolism, and senescence. Age-related changes cause a decline in mitochondrial quality and integrity due to increased mitochondrial mutations and oxidative damage. Thus, aging can severely impact mitochondrial functions,...
The Inner Mitochondrial Membrane01:28

The Inner Mitochondrial Membrane

The inner mitochondrial membrane is the primary site of ATP synthesis. The inner membrane domain that forms a smooth layer adjacent to the outer membrane is called the inner boundary membrane. This domain contains membrane transporters that drive metabolites in and out of the mitochondria.  In contrast, the inner membrane network that invaginates into the matrix space is called the cristae membrane. This domain accounts for principle mitochondrial function as it accommodates the protein...
Translocation of Proteins into the Mitochondria01:19

Translocation of Proteins into the Mitochondria

Mitochondrial precursors are translocated to the internal subcompartments via independent mechanisms involving distinct protein machineries called translocases.
Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...
ATP Synthase: Mechanism01:48

ATP Synthase: Mechanism

In animals, the mitochondrial F1F0 ATP synthase is the key protein that synthesizes ATP molecules through a complex catalytic mechanism. While the nuclear genome encodes the majority of ATP synthase subunits, the mitochondrial genome encodes some of the enzyme's most critical components. The formation of this multi-subunit enzyme is a complex multi-step process regulated at the level of transcription, translation, and assembly. Defects in one or more of these steps can result in decreased ATP...
Mitochondrial Membranes01:45

Mitochondrial Membranes

A single mitochondrion is a bean-shaped organelle enclosed by a double-membrane system. The outer membrane of mitochondria is smooth and contains many porins - the integral membrane transporters. Porins enable free diffusion of ions and small uncharged molecules through the outer mitochondrial membrane but limit the transport of molecules larger than 5000 Daltons. Further, the outer mitochondrial membrane forms a unique structure called membrane contact sites with other subcellular organelles,...
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...
