Seminal Analysis

Seminal Analysis

Semen analysis is used to evaluate male fertility. Many crucial information about male genitourinary problems can also be revealed clinically by doing a complete semen analysis. This test is used to assess some genitourinary problems of men as the semen is a combination of secretions from various glands. The test will reveal the healthiness of a man’s genitourinary system.
MHS provides semen analysis at HK$400.

Things You Should Know For The Test
1.Collect the semen in a sterile bottle through masturbation. (Collect the bottle in our clinic first). Do not collect it in a condom
2.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.
3.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.

The World Health Organization (WHO) Has Developed The Following Values For Normal Semen Analysis

Standard Tests Normal Values
Liquefaction Within 45 minutes in room temp
Color Grey-white
Volume 2.0 ml or more
pH 7.2 ~ 8.0
Sperm concentration 20 x 106 spermatozoa / ml or more
Total sperm count 40 x 106 spermatozoa more
Vitality 75% or more live
Motility 50% sperm with forward movement, or 25% with rapid movement within 1 hour of ejaculation.
Morphology 30% or more with normal sperm
White blood cells Fewer than 1 x 106 / ml

What Does The Test Result Mean

Sperm concentration (also called sperm density) is measured in millions of sperm per millilitre of semen. Levels greater than or equal to 20 million per millilitre (and more than 80 million sperm in one ejaculation) are considered normal. The fewer sperm a sample has, the less chance a man has of getting his partner pregnant. A man who has just had a vasectomy would expect no sperm in his sample.

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 is 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).
