02 Jan How to evaluate Male Infertility?
Infertility affects both men and women, is devastating, upsetting, and emotionally challenging, and many of the risk factors are rooted in behavior that begins in adolescence. However, when it comes to male infertility, men find it difficult to understand that they are suffering from it. To evaluate, male infertility, it is important to go for semen analysis. The quality of semen as his sperm must be healthy and strong enough for successful fertilization to occur. It is estimated around 15 percent of couples are unable to conceive a child after a year or more of unprotected sex. For this process, a man has to make sure that he needs to know about the semen analysis and sperm tests that will eventually build up his family.
What is Semen Analysis?
Semen analysis is the most common test performed to men to assess male fertility. The test determines whether his semen has ability to get a woman pregnant. The semen analysis consists of a series of tests that calculates the sperm count (to see how many), the ability of sperm to swim (motility), the size and shape of the sperm (morphology) velocity of forward progression and total volume.
Where the test is done?
The test for semen analysis is usually done at fertility clinics. The sperm is collected through masturbation. Our IVF clinic in Delhi has arranged a room for men for the collection of semen in a sterile container that is later examined for tests results. Using lubricants during masturbation for the collection of sperm can be a good idea than saliva as the latter can damage the sperm.
The tests result for the semen sample is evaluated as:
What should be the normal sperm count?
The normal sperm count should be around 15-20 million+ sperm per milliliter that makes your partner pregnant. The World Health Organization figures define, a sperm concentration of 20 million per milliliter, and a total of at least 40 million per ejaculate, is needed for optimum fertility. Men with absence of sperm or no semen in their sperm called as azoospermia.
Total Volume, Sperm Motility and Morphology is also evaluated
The typical volume of semen collected is between 1.5 and 5.5 milliliters (mL) of fluid per ejaculation. The decreased volume of semen indicates fewer sperm, which decreases the chances for successful fertilization and subsequent pregnancy. Sperm motility is defined as the percentage of moving sperm in a sample and graded based on speed and direction travelled. At least 50% should be motile one hour after ejaculation, moving forward in a straight line with good speed. And morphology is the study of the size, shape, and appearance of the sperm cells. The analysis evaluates the structure of the sperm, whereby greater than 50% of those cells examined must be normal in size, shape, and length.
