  • 4.7 (6 Votes)

Sperm Motility refers to the movement and swimming capability of a sperm. Motility is a standard measurement to know whether a sperm can swim properly inside a womens uterus and fallopian tube. Normal values are more than 50% and below 25% its considered almost infertile.

Sperms are called swimmers due to their characteristic of travelling in the uterus and fallopian tubes. For developing an embryo, a sperm cell needs to be optimal in both - motility and morphology. It is measured as part of a given semen sample and forms a very crucial aspect to checking male fertility. However, not everybody has a healthy motility because of genetic flaws or medical conditions developed as part of unhealthy lifestyle.

What is the Normal Sperm Motility?

For reaching the egg, the sperm must have the ability to swim. Normal sperm motility is quite important to understand as it plays a major role in men's reproductive health. There are least chances of natural conception and pregnancy if sperms are not motile. Normal Sperm Motility refers to a sperm with a characteristic of more than 50% as motility value for a single ejaculation. A motility value between 25% and 50% is considered borderline. But if it is below 25%, then it means that chances of conceiving are too low.

What is Low Sperm Motility?

Low Sperm Motility is a situation where the sperm has a difficult time reaching the egg in order to fertilize it. For such cases, Motility figures are below 25%.

How to achieve parenthood with low sperm motility?

Low sperm motility doesn't imply the end of impregnating abilities. There are several alternative treatments to help you conceive even with a low sperm Motility. They are as follows:

1- Intrauterine Insemination (IUI): It is a process of artificial insemination and involves placing of sperm in the woman's uterus by reducing the swimming amount required for it to reach the egg. This procedure begins if the sperm has motility of 30 to 35% at least.

2- In Vitro Fertilization (IVF): This is the most popular treatment available under Assisted Reproductive Technology (ART). Here, the doctors fertilize the female's eggs with male's sperm. There are high chances of pregnancy due to controlled environment settings.

In Vitro Fertilization

3- Intracytoplasmic sperm injection (ICSI): This treatment occurs during IVF process where the man's sperm injection is used directly into the egg for continuing the fertilization. This process can be started regardless of motility and has a success rate of 70 to 90%.

How many swimmers does it need for embryo development?

The answer to this question is just 'One'. For fertilizing the egg, only one sperm is enough. Nature directs sperms to the right destination but because of journey's difficulty many of them end up in premature death. So, for completing the fertilization process naturally one needs to direct as many as possible sperm cells to the egg so that at least one reached the egg.

    Having low sperm count along with abnormal sperm morphology results in infertility. IUI, IVF, and ICSI should be opted by people as their treatment option.
