Everyone knows sperm swims to the egg to cause fertilization and bring about pregnancy.

What happens if this sperm, for one reason or another, can’t make it to the egg?

You guessed right; getting pregnant is impossible.

This is exactly what happens with many women.

You see, sperm can survive inside your reproductive tract for up to five days,

But their survival depends on the environment they encounter.

The vagina is naturally acidic, which can kill weaker sperm within minutes.

However, your body naturally produces this fluid called cervical mucus during your menstrual cycle. It’s supposed to help sperm swim through your cervix and meet your egg.

But sometimes, this mucus becomes a barrier instead of a helper. It might be too thick, too harsh for the sperm to survive, or just not enough, making it hard for sperm to pass through.

And thereby making fertilization not take place

Not only that, the sperm sometimes contributes to the cause of infertility

Instead of swimming forward after intercourse, the sperm may flow downward, moving away from where it should be.

Or it might be too weak or slow to reach your egg, which means fertilization never happens.

And as a result, you’re left with a frustrating cycle of disappointment, where pregnancy feels impossible.
