Summary
Semen volume and fructose levels in azoospermic men were analyzed. Low semen volume in azoospermic samples correlated with reduced fructose concentration, unlike in sperm-containing samples.
Area of Science:
- Andrology
- Reproductive Medicine
- Urology
Background:
- Azoospermia, the absence of sperm in ejaculate, affects male fertility.
- Semen parameters like volume and fructose concentration are crucial for reproductive health assessments.
- Understanding variations in these parameters in azoospermic individuals is important for diagnosis.
Purpose of the Study:
- To investigate semen volume and fructose concentration in azoospermic men.
- To compare these parameters with those in sperm-containing samples.
- To explore correlations between semen characteristics, azoospermia etiology, and hormonal profiles.
Main Methods:
- Analysis of 260 semen volume measurements and 265 fructose determinations from 257 azoospermic samples.
- Categorization of semen volume as normal (1-6 mL), low, or high.
- Comparison of fructose concentrations across different volume groups and with sperm-containing samples.
- Assessment of correlations with azoospermia etiology and serum hormone levels (LH, FSH, testosterone, prolactin).
Main Results:
- 78% of azoospermic samples had normal semen volume, 16.7% low, and 5.2% high.
- Low semen volume was more prevalent in azoospermic samples compared to sperm-containing samples.
- Mean fructose concentration was significantly lower in low-volume azoospermic samples than in normal or high-volume ones.
- No significant correlation was found between azoospermia etiology and abnormal semen volume/fructose, except for obstruction/atrophic seminal vesicles.
- No correlation was observed between semen volume, fructose concentration, and serum LH, FSH, testosterone, or prolactin levels.
Conclusions:
- Abnormal semen volume, particularly low volume, is a notable finding in azoospermic individuals.
- Reduced fructose concentration is associated with low semen volume in azoospermia.
- Semen volume and fructose levels in azoospermic men do not strongly correlate with specific etiological factors or key reproductive hormones, with exceptions noted.
