Yes, sperm need to move effectively to achieve pregnancy. This movement is called motility, and it is crucial for sperm to reach and fertilize an egg.
Understanding Sperm Motility
To fertilize an egg, sperm must navigate through the female reproductive system, including the cervix, uterus, and fallopian tubes. This journey requires the sperm to wriggle and swim effectively. Sperm motility refers to the ability of sperm to move efficiently.
Importance of Sperm Motility
- Reaching the Egg: Sperm motility is essential for sperm to swim to the egg in the fallopian tubes.
- Penetrating the Egg: Adequate sperm motility can aid in penetrating the outer layers of the egg for fertilization.
Motility Threshold
According to available information, pregnancy can be possible even if less than 40% of the sperm in the ejaculate are moving. However, 40% is considered the threshold, and a higher percentage of motile sperm generally increases the chances of conception. As a general rule, the more motile sperm, the better the chances of pregnancy.
Table: Sperm Motility and Fertility
| Motility Percentage | Fertility Potential |
|---|---|
| Below 40% | Reduced |
| 40% or Higher | Generally Good |
