What is this test?
The Semen Calcium Test measures the amount of calcium present in semen. Calcium is an important electrolyte that plays a role in sperm motility (movement) and overall sperm health. This test helps healthcare providers evaluate male fertility potential and identify potential issues with the reproductive system.
How is the test performed?
You will be asked to collect a semen sample, usually through masturbation, into a sterile container. It is typically recommended to abstain from sexual activity for 2-5 days before collecting the sample. The sample is then sent to a laboratory where the calcium concentration is measured using specialized equipment.
Why might I need this test?
This test may be ordered if you are experiencing fertility problems or have been unable to conceive a child with your partner. It may also be part of a comprehensive fertility evaluation or if your healthcare provider suspects issues with your reproductive system.
Reference range
20-40 mg/dLnot specified
Abstain from ejaculation 2-7 days; collect entire sample by masturbation into sterile container without lubricants
