What is this test?
The Semen Calcium test measures the amount of calcium in your semen (the fluid that contains sperm). Calcium is a key mineral that plays a vital role in sperm movement (motility) and the sperm's ability to fertilize an egg. This test is typically performed as part of a comprehensive semen analysis to evaluate male fertility.
Why is it done?
Your healthcare provider may order this test if you are having trouble conceiving a child. Calcium levels in semen can affect how well sperm function. Both too high and too low calcium levels may contribute to fertility problems. The test helps doctors understand if a mineral imbalance might be affecting your ability to father a child.
How is the sample collected?
You will need to provide a semen sample, usually collected through masturbation into a sterile container. You may be asked to abstain from sexual activity for 2-5 days before the test to ensure accurate results. The sample is then sent to a laboratory where the calcium concentration is measured.
What do the results mean?
Results are typically given as millimoles per liter (mmol/L). Normal calcium levels in semen vary, but abnormal results may indicate potential issues with sperm function. Your doctor will interpret your results along with other semen analysis parameters to get a complete picture of your fertility health.
