Male infertility is often linked to sperm issues, while female infertility usually revolves around ovulation. Sperm motility, or the ability of sperm to move effectively, is crucial for achieving pregnancy.
The Journey of Sperm
During natural conception, sperm must swim up the cervix, through the uterus, and into the fallopian tubes to reach the egg.
A low sperm count means fewer sperm can make this journey, reducing the chances of fertilization. Even if sperm reach the egg, they may not penetrate its tough exterior, leading to unsuccessful fertilization.

Sperm motility refers to the ability of sperm to move. For fertilization, sperm must not only move but also swim from one place to another.
In a semen analysis test, normal sperm motility is when at least 40% of sperm are moving.
Normal Sperm Motility Percentage for Pregnancy
Progressive motility, which is the ability to move from one place to another, is crucial. If a man has 40% total motility, about 32% should be progressively motile, which is considered normal for achieving pregnancy.
A minimum of 12% of sperm should swim straight for a successful conception.
Factors Affecting Sperm Motility
Poor sperm motility impacts fertility. Several factors can lead to low sperm motility, including genetic defects, lifestyle choices, and environmental influences.
Couples struggling with low sperm motility have several assisted reproductive options.
Intrauterine Insemination (IUI)
For sperm motility of 30% to 40%, IUI involves injecting healthy sperm directly into the uterus, reducing the distance they need to travel.
Intracytoplasmic Sperm Injection (ICSI)
For minimal sperm motility, ICSI involves directly injecting a single sperm into an egg. This method is highly effective and commonly used in IVF treatments, boasting an 80% success rate in fertilization.
Conclusion
Sperm motility is a crucial factor in male fertility. Understanding its impact and knowing how to improve it can significantly increase the chances of achieving pregnancy.
With lifestyle changes, dietary adjustments, and assisted reproductive technologies, couples facing motility issues can still achieve successful pregnancies.
Frequently Asked Questions
Sperm motility is the ability of sperm to move properly towards an egg to fertilize it.
Sperm needs to swim to the egg to fertilize it, so good motility is important for pregnancy.
Factors like smoking, drinking alcohol, poor diet, stress, and certain medical conditions can cause low sperm motility.
Yes, doctors can prescribe medications or recommend treatments like in vitro fertilization (IVF) to help.
Foods rich in antioxidants, like fruits, vegetables, nuts, and seeds, can help improve sperm motility.
Yes, high stress levels can negatively affect sperm motility.
Doctors use a semen analysis to test sperm motility by looking at a sample under a microscope.
Yes, certain supplements like zinc, folic acid, and vitamin C can help improve sperm motility.
Sperm motility refers to how well sperm can swim, while sperm count is the number of sperm present in a sample.
Yes, infections can damage sperm and affect their ability to swim.
Yes, high temperatures, such as from hot baths or tight clothing, can reduce sperm motility.
Sperm motility is typically assessed as the percentage of moving sperm in a semen sample. Normal motility is considered to be 40% or higher, with progressive motility (sperm moving actively forward) being 32% or more. Values below these ranges
indicate potential issues.
