Summary
Seminal transferrin (TF) levels correlate positively with sperm count in fertile and infertile men. Lower TF concentrations were observed in men with azoospermia or severe oligospermia, indicating TF
Area of Science:
- Reproductive biology
- Andrology
- Biochemistry
Background:
- Seminal plasma contains various proteins crucial for sperm function and fertility.
- Transferrin (TF) is an iron-binding protein present in seminal fluid, but its specific role in male fertility is not fully elucidated.
Purpose of the Study:
- To investigate the relationship between seminal transferrin (TF) concentrations and sperm count in a cohort of infertile men and fertile controls.
- To determine if TF levels correlate with other seminal parameters or hormonal profiles.
Main Methods:
- Radioimmunoassay was employed to quantify TF concentrations in semen samples.
- Semen analysis included sperm count and assessment of other seminal parameters.
- Hormonal values were also analyzed for correlation.
Main Results:
- A significant positive correlation was observed between seminal TF concentration and sperm count across all participants and within the fertile control group.
- Patients with azoospermia and severe oligospermia exhibited statistically lower TF concentrations compared to other groups.
- No significant correlation was found between seminal TF levels and other seminal parameters or measured hormonal values.
Conclusions:
- Seminal transferrin concentration is positively associated with sperm count in men.
- Reduced seminal TF levels may serve as a potential biomarker for severe sperm production defects like azoospermia and severe oligospermia.
