Summary

This study introduces a modified histochemical reaction to measure arginine in sperm, serving as an index for sperm maturation. The technique shows promise for evaluating sperm quality in normal and oligospermic individuals.

Background:

Sperm maturation is crucial for male fertility.
Accurate assessment of sperm quality is essential in reproductive medicine.
Histochemical methods offer potential for evaluating sperm parameters.

Purpose of the Study:

To propose a modified Sakaguchi reaction for quantifying arginine in spermatozoa.
To establish arginine content as a reliable index of sperm maturation.
To validate the utility of this histochemical technique in assessing sperm quality.

Main Methods:

A modified Sakaguchi histochemical reaction was developed.
Arginine content in spermatozoa was evaluated.
Comparisons were made with DNA and basic nuclear protein determinations.
Sperm samples from normal subjects and patients with oligospermia were analyzed.

Main Results:

The modified Sakaguchi reaction successfully quantified arginine in spermatozoa.
Arginine content correlated with sperm maturation.
The technique demonstrated usefulness in differentiating sperm quality between normal and oligospermic groups.
Results were consistent with DNA and basic nuclear protein analyses.

Conclusions:

The modified Sakaguchi reaction provides a valuable tool for assessing arginine content in spermatozoa.
This method serves as a reliable index for sperm maturation.
The technique is useful for evaluating sperm quality in clinical settings, including cases of oligospermia.
