Inositol activity in oligoasthenoteratospermia--an in vitro study

Area of Science:

• Reproductive biology
• Andrology
• Biochemistry

Background:

• Oligoasthenoteratospermia is a primary cause of male infertility.
• Morphologically altered spermatozoa produce reactive oxygen species (ROS), damaging sperm motility, morphology, and DNA.
• Spermatozoa are particularly vulnerable to ROS-induced damage.

Purpose of the Study:

• To investigate inositol as a potential antioxidant for male infertility.
• To assess inositol's efficacy in improving in vitro sperm quality for assisted reproduction.

Main Methods:

• Sperm samples from infertile and healthy men were analyzed using phase contrast microscopy.
• Samples were treated with inositol (2 mg/ml) and examined via scanning electron microscopy (SEM) and transmission electron microscopy (TEM).
• SEM evaluated surface morphology changes; TEM assessed ultrastructural details.

Main Results:

• Pathological sperm samples showed fibrous material hindering motility and damaged mitochondria with altered cristae.
• Inositol treatment reduced the fibrous material and improved mitochondrial morphology, with less cristae damage.
• These changes suggest inositol may alter seminal fluid properties and protect sperm mitochondria.

Conclusions:

• Inositol exhibits antioxidant properties potentially targeting sperm mitochondria.
• Preliminary findings suggest inositol's benefit for oligoasthenoteratospermia.
• Further research is needed to correlate ROS levels, inositol treatment, and oligoasthenoteratospermia outcomes.
