Semen Analysis
Semen Analysis
Semen analysis, also known as sperm analysis or semen evaluation, is a laboratory test that assesses the quality and quantity of a man’s semen and sperm. This test is essential for evaluating male fertility and diagnosing potential reproductive issues.
Key Parameters Assessed in Semen Analysis
Volume:
- The total amount of semen produced during ejaculation. A normal volume is typically between 1.5 to 5 milliliters.
Sperm Concentration:
- The number of sperm present in a given volume of semen, measured in millions of sperm per milliliter. A normal concentration is generally considered to be 15 million sperm per milliliter or more.
Motility:
- The percentage of sperm that are moving and their movement quality (progressive motility). Normal motility is defined as at least 40% of sperm being motile.
Morphology:
- The shape and structure of sperm cells, which can affect their ability to fertilize an egg. A normal morphology rate is typically assessed using strict criteria, with at least 4% of sperm having a normal shape.
pH Level:
- The acidity or alkalinity of the semen, with normal levels typically ranging from 7.2 to 8.0.
White Blood Cell Count:
- The presence of white blood cells in semen can indicate infection or inflammation.
Fructose Level:
- Fructose is a sugar that provides energy for sperm; low levels may indicate issues with the seminal vesicles.
Importance of Semen Analysis
- Fertility Assessment: Semen analysis is often one of the first tests performed when evaluating male infertility. It helps identify potential issues that could affect a couple’s ability to conceive.
- Diagnosis of Conditions: Abnormal results can indicate various conditions such as oligospermia (low sperm count), asthenozoospermia (poor motility), teratozoospermia (abnormal morphology), or infections.
- Monitoring Treatment: For men undergoing treatment for infertility, repeat semen analyses can help monitor progress and the effectiveness of interventions.
Factors Affecting Semen Quality
- Smoking, excessive alcohol consumption, drug use, poor diet, and lack of exercise can negatively impact semen quality.
Medical Conditions:
- Conditions such as diabetes, hormonal imbalances, infections, and genetic disorders can affect sperm production and quality.
- Exposure to toxins, heavy metals, and radiation can impair sperm production and function.
Age:
- Male fertility generally declines with age, particularly after the age of 40.
