Insights
Seminal cystatin levels are lower in men undergoing chronic hemodialysis. These levels correlate with sperm parameters, aiding in the evaluation of male infertility.
Area of Science:
- Nephrology
- Reproductive Medicine
- Biochemistry
Background:
- Chronic hemodialysis can impact male reproductive health.
- Seminal parameters are crucial for fertility assessment.
- Cystatin C is a protein with various physiological roles.
Purpose of the Study:
- To explore the relationship between seminal cystatin C levels and seminal parameters in men undergoing chronic hemodialysis.
- To assess the potential role of seminal cystatin C in evaluating infertility in this patient group.
Main Methods:
- A cross-sectional study comparing 60 men on chronic hemodialysis with 15 healthy controls.
- Semen analysis (spermogram), hormonal profile, and seminal leukocyte and cystatin C levels were assessed.
- Participants were aged 18-60 years and free from genitourinary infections.
Main Results:
- Seminal cystatin C levels were significantly lower in the hemodialysis group compared to controls (41.16 ± 26.59 vs. 79.00 ± 05.68 mg/l, p < 0.001).
- Lower seminal cystatin levels were observed in men with oligospermia compared to normospermia (30.34 ± 02.52 vs. 83.50 ± 02.40 mg/l, p < 0.001).
- Seminal cystatin levels positively correlated with sperm motility and sperm density (p < 0.05).
Conclusions:
- Seminal cystatin C levels are significantly altered in men undergoing chronic hemodialysis.
- These levels are associated with changes in sperm count and motility.
- Seminal cystatin C may serve as a useful biomarker in the initial assessment of subfertility and infertility in chronic hemodialysis patients.
Objective:
We aimed to investigate the possible relationship between seminal parameters and cystatin C seminal levels in an infertility evaluation of chronic hemodialysis patients.
Materials And Methods:
This was a cross-sectional study, aged 18-60 years, in a group of 60 men undergoing hemodialysis (case) for more than 6 months, and a group of 15 healthy men (control) without clinical or laboratory signs of genitourinary tract infection. We performed a spermogram, hormonal profile, and assessment of leukocytes and cystatin levels in the semen.
Results:
The ages in the case and control were similar (p = 0.060). The seminal cystatin was significantly different between the case group and control group (41.16 ± 26.59 vs. 79.00 ± 05.68 mg/l, respectively, p < 0.001) and between normospermia and oligospermia (83.50 ± 02.40 vs. 30.34 ± 02.52 mg/l, respectively, p < 0.001). The mean seminal cystatin levels identified by the degrees of oligospermia (severe, moderate, and slim) were similar to each other (p > 0.05) and significantly different (p < 0.05) in relation to normospermia in the case group. The seminal cystatin levels positively correlated (p < 0.05) with sperm motility and sperm density.
Conclusion:
Seminal cystatin levels are associated with the numerical and motility changes evidenced in the spermogram and may be of help in the initial evaluation of clinical suspicion of sub-fertility and infertility.
