Understand your fertility. Know your options.

When people hear the word fertility, they often think of a simple yes or no question.

Fertility is a series of biological steps that need to come together, often at just the right time.

Here are those steps, and why one test rarely tells the whole story.

Step 1 of 6: an egg is released. Once in each cycle, usually one mature egg leaves an ovary. This is ovulation.

Step 2 of 6: a tube collects the egg. The finger-like ends of the fallopian tube gently sweep the egg inside.

Step 3 of 6: sperm reach the egg. They travel through the cervix and uterus into the tubes. Only a small fraction get that far.

Step 4 of 6: fertilisation. One sperm enters the egg and their genetic material combines, usually in the fallopian tube.

Step 5 of 6: the embryo develops. Over the next few days it divides into more and more cells as it moves along the tube to the uterus.

Step 6 of 6: the embryo implants. It attaches to the lining of the uterus, usually starting about six to seven days after fertilisation.

Each step depends on a different part of the body working well. That is why fertility can’t usually be understood from a single test.

A blood test tells you about one step. A semen analysis tells you about another. No single test checks them all.

Fertility involves both partners. Sperm health is part of the picture from the very beginning.

Why it can take months. Even when everything is working well, pregnancy doesn’t happen every cycle. Each month brings a chance, and over several months those chances add up.

Taking a few months is common. More than 8 in 10 couples conceive within a year of regular unprotected sex, when the woman is under 40.

If you are older, or something in your history concerns you, speak to a healthcare professional sooner.

Kara’s key takeaway: fertility involves several biological steps. Both female and male factors may need to be considered. A single test rarely tells the whole story. Taking several months to conceive is common.
