We have all heard that the fastest sperm wins the race to life. But what if the swimmers are not racing at all? Sperm motility is the term we use to describe the efficiency with which sperm move toward the egg. Sperm motility is calculated as a percentage and helps determine your fertility. This article covers everything about this sperm feature and the ideal percentage. So, let’s get started!
Sperm motility refers to the ability of sperm to move with proper speed and direction. This movement is essential because sperm must travel through the cervix, uterus, & fallopian tubes to reach the egg. If sperm cannot swim well, they may not complete this journey, which reduces the chances of natural conception.
Semen analyses shows the percentage of motile sperm and their motility, measured by forward movement. When a sperm cell's motility is high, it can move quickly, whereas a low motility score may indicate health problems and lifestyle factors.
By understanding how sperm move, a couple can plan for challenges when trying to conceive and take the proper steps in pursuing pregnancy.
Sperm motility determines how strong and stable the sperm are in reaching the egg. It does not depend upon any other feature of sperm. That is, no number of sperm in semen can make fertilisation possible if they can’t swim properly through the reproductive tract. This directly impacts the survival of sperm in their journey towards the egg.
Low motility slows down the movement of sperm and increases the time sperm remain in the hostile environment of the uterus. Ultimately, this makes natural conception challenging. Therefore, when it comes to pregnancy and its chances, sperm motility matters the most, just like other factors do.
Sperm motility is evaluated by observing how actively and effectively sperm move. This helps determine whether they can travel through the female reproductive tract and reach the egg in time. Interestingly, sperm motility can be defined in different ways. Each of these types of movement reflects a different level of fertility potential, which is why understanding these categories is essential during a semen analysis:
Note that a higher percentage of progressive motility increases the chances of natural conception.
As per the international standards of the World Health Organisation, not only the quantity of moving sperm, but also their quality of moving forward determines the chances of a successful conception and pregnancy. The ideal sperm motility percentage is a clear reference value used as a threshold to assess a man's sperm health and fertility.
Here are the recommended motility standards of the WHO:
| Mobility Type | Normal Percentage for Pregnancy |
|---|---|
| Total Motility (Progressive and Non-progressive) | ≥40% |
| Progressive Motility | ≥32% |
| Non-Progressive Motility | 30% |
| Immotile Sperm | The lower the better |
Sperm are a sensitive bioproduct, meaning any change in internal or surrounding factors can disrupt sperm health, including motility. Considering its importance, identifying each of these factors can help improve or treat abnormality in sperm motility, which includes:
The treatment plan for low sperm motility depends on the cause of the low motility, the sperm type, and the person's needs. Essentially, its treatment will specifically be based on whether the affected male is trying just to improve their quality of sperm or trying to conceive with his partner. Some of the most common treatments include:
The goal of each of the above-mentioned treatment options is the same: improving sperm movement efficiency so it can reach the egg, on time.
A major issue for male-factor infertility in the world, due to late discovery and delayed treatment, is sperm motility (the ability for sperm to swim effectively). For this reason, it is essential to see a physician as soon as possible, that is:
Finally, it can be concluded that understanding sperm motility is essential for couples trying to conceive. While normal total sperm counts may be evident in men experiencing delays in achieving pregnancy, it can also relate to a lack of or slow motility. It can help identify problems at an early stage. Once detected, many men have the opportunity to increase motility and may be able to achieve a successful, healthy pregnancy through appropriate lifestyle modifications, medical support, or fertility treatment options. Taking action promptly is essential to having a successful outcome.
Dehydration can cause semen to become thick, ultimately making sperm move more slowly than usual.
Ejaculating very frequently in the short term can result in a temporary reduction in sperm motility.
Some medications (e.g., Antibiotics and Anabolic Steroids) have been shown to decrease Sperm motility.
Both inadequate sleep quality and irregular sleep patterns will have a direct negative effect on sperm health and movement.
Yes, the natural decline in Sperm Quality and Motility begins at approximately 40 years of age.
