Men with vasectomy should produce a sample for semen analysis on several occasions until the results show that no sperm are present. They will also need to use other forms of birth control to prevent pregnancy until this has happened.
The sample is usually provided by masturbation into a sterile container or through the use of a special non-spermicidal lubricant that can be obtained from the laboratory.
How to read a sperm analysis report
A semen analysis is a lab test that evaluates the number and type of sperm in ejaculated semen. It is an important part of male fertility testing and can help a couple determine whether there are health problems that may cause infertility. In some cases, a semen analysis is also used to confirm a vasectomy procedure was successful.
The test analyzes a sample of freshly ejaculated semen and evaluates the number of sperm, their movement (motility), and their shape or morphology. It can be performed at a fertility clinic, but it can also be done at home with special equipment. Semen samples are usually collected without the use of lubricants or saliva, as these substances can harm sperm.
If a man has a low sperm count, he will be referred to a reproductive urologist for treatment. In addition to performing a semen analysis, the doctor will consider the man’s health history and other factors when developing a treatment plan.
Because sperm levels can change between samples, the test may need to be repeated in order to obtain accurate results. In addition, illness, fevers and infections can lower sperm quality, so it’s important to provide several samples for a more complete assessment of a man’s fertility. Depending on the results, a urologist can recommend first-line treatments or assisted reproductive technology, such as intrauterine insemination.
Sperm count
A semen analysis can determine if a man’s fertility is impacted by problems with sperm production or quality. It can also help to determine whether a vasectomy was successful. The test examines a sample of a person’s semen and checks for certain qualities, such as sperm concentration, motility and morphology. It can also test for other factors, such as seminal fluid volume and the presence of leukocytes.
To get the most accurate results, a man should avoid any sexual activity for several days before the test. He should also use a special condom to collect the sample. If he masturbates, the sample should be collected in a special container that is clean and can be easily transported to the lab. It is also important to avoid using saliva or other lubricants.
Using a special condom is the preferred method because it provides a more consistent sample. Some healthcare providers can collect the semen onsite, while others will recommend that men ejaculate into a collection cup at home. It is recommended that people provide multiple samples spaced a few weeks apart to see the trend of the sperm count. This will also help to rule out the possibility of recanalization. A patient recently told us that he had a PVSA done after a vasectomy. The sample showed no sperm and his wife later conceived, so the vasectomy was successful.
Sperm motility
If sperm want to get to an ovulated egg and fertilize it, they must move in order to reach their ultimate destination. During sexual intercourse, semen is ejaculated near the cervical canal and must make its way up this tube to meet an egg. This requires sperm to be active, and a PVSA can determine how many of your sperm are moving.
The PVSA can also determine the shape and motility of your sperm, which are crucial factors in fertility. It can also test for acidity (pH) and white blood cells in the sample. These can indicate an infection or other health conditions.
It is important to remember that the results of a semen analysis are not conclusive. A low sperm count does not mean you will become permanently infertile, but it does suggest that there may be an issue that needs to be addressed.
It is also worth noting that it takes a lot of effort for a person to collect a semen sample. This is why it’s recommended to provide more than one sample over a three-month period. This is because a person’s sperm profile can vary from day to day. It’s also possible to get a false negative if the semen is collected improperly. For this reason, it’s important to follow your doctor’s instructions for collection.
Sperm concentration
A sperm concentration is a measurement of the number of moving sperm in a sample of semen. This is measured using a counting chamber, or hemocytometer. A normal semen sample will contain more than 20 million sperm cells per milliliter. The sperm count and motility are important factors when evaluating fertility in men. A sperm sample is considered to be of good quality if more than 60% of the sperm are moving.
Other measurements taken during a sperm analysis include the volume of a single ejaculation, and the size and shape of the sperm (morphology). The semen also is evaluated for its acidity or alkalinity, known as its pH. The pH is usually within 7.2 and 7.8. A low pH is an indicator of a problem with the vas deferens, while a high pH indicates a problem in the seminal vesicles.
A sperm analysis is often performed as part of an infertility investigation, or to determine whether a vasectomy was successful. It can help doctors decide the best course of treatment for a patient. For example, they might recommend other tests to identify the cause of infertility. In addition, they might recommend alternative methods of contraception or explore other options, such as donor sperm or adoption.
