Seminal Analysis (HK$400)
Seminal analysis is a basic test to evaluate semen quality which helps reproductive endocrinologists to examine the cause of male infertility.
Test Items of Seminal Analysis
- Total Volume
- Sperm count
- Sperm motility
- Sperm morphology
- Sperm WBC
- Sperm RBC
The test is recommended for
- Men with marriage or birth plan, who want a preliminary assessment on semen quality
- Men who want to check the effectiveness of vasectomy
|Test Item||Test Fee|
*The fee above does not include doctor’s report explanation. An extra cost of HKD350 will be charged if patients require doctor’s report explanation.
*Seminal Analysis is only used to evaluate basic criteria of semen quality. If fertility evaluation is required, you should consult reproductive endocrinologists for a comprehensive check-up and assessment, including medical history, physical examination, genitourinary system examination, endocrine examination etc.
Things you should know for the test
- Collect the semen in a sterile bottle through masturbation. (Collect the bottle in our clinic first). Do not collect it in a condom.
- No ejaculation for 5-7 days before the test. Masturbation to have the specimen in our clinic or at a place where you feel comfortable. Abstinence for too long or too short will affect the quality of semen.
- The sample must be returned to our clinic within 1 hour. Keep the sample close to the body to keep it warm. Do not put it into ice or refrigerator.
What does the test result mean
The percentage of moving sperm in a sample is known as its ‘motility’. The more slowly moving or immobile sperm in a sample, the less likely it is that a man could conceive a child with his partner. The progression of the sperm is rated on a basis from zero (no motion) to 3 or higher for sperm that move in a straight line with good speed. If less than half of the sperm are moving, a stain is used to identify the percentage of dead sperm. This is called a ‘sperm viability test’.
Morphology analysis is the study of the size, shape, and appearance of the sperm cells. The analysis evaluates the structure of 200 sperms, and any defects are noted. The more abnormal sperms that are present, the more the likelihood of infertility.
Several factors can affect the sperm count and other semen analysis values. A man may have a lower sperm count if he has physical damage to the testicles, has gone through radiation treatment of his testicles, or has had exposure to certain drugs (such as azathioprine). A man with a higher level of oestrogens may have a lower sperm count.
Some of the common causes of male infertility are extremely high fever, testicular failure (failure of the testicles to produce sperm), obstruction of the tubes that carry semen to the penis, and a less than normal amount of sperm in the sample (oligospermia).
