Semen, not sperm, affects sperm velocity, but unhealthy lifestyle choices and genetics can impact sperm motility. Caffeine can temporarily increase sperm rate, but excessive consumption can be harmful. A doctor can check for genetic defects or hormonal conditions affecting sperm health through a semen sample. Overall health is more important than sperm speed, but motility is crucial for fertilization.
Technically, there are no factors that affect sperm velocity, as semen is the fluid in which sperm cells reside. It is made up of fructose and other substances and provides a protective barrier for sperm cells so they can survive the acidic environment of the vagina. Sperm velocity, however, can be affected by unhealthy lifestyle choices or genetic factors. Many people use the terms “semen” and “sperm” interchangeably, although they are actually two separate entities.
When asked about sperm speed, most males want to know if there is anything they could be doing to affect sperm motility. There are various behaviors that males can partake in that can negatively impact their sperm rate and overall health. Smoking tobacco, for example, can be associated with abnormal sperm with low motility. Deficiencies of some vitamins can also affect sperm rate.
Some substances have been tested to determine if they affect ‘sperm speed’. Caffeine, for example, has been tested and found to increase male sperm rate for a temporary period of time. The exact amount needed can be different for every man. It is not recommended for men to drink unusual amounts of caffeine in an attempt to improve fertility, as this can have adverse health effects.
If a patient asks a doctor to check their sperm rate, it is usually referring to sperm motility. Besides maintaining a healthy lifestyle by avoiding medications and maintaining a healthy weight, there are other factors that can come into play when it comes to male fertility. Certain genetic defects or hormonal conditions can also affect sperm rate and health and are usually checked for during an exam.
The exam used to test sperm motility usually involves ejaculating a man into a sterile cup. This is achieved through masturbation which is performed in a fertility clinic. Once the seed has been collected, it is examined under a microscope. The sperms are then visible, and a doctor can see if there are any misshapen, slow, or dead sperms.
Many defects can be corrected through surgery or hormone replacement therapy. Semen samples may be taken at intervals to test overall health. Sperm speed isn’t as important as overall health, but since they can only live a few days once they enter the female body, it’s important that they move well enough to reach and fertilize an egg.
