When pregnancy does not happen as quickly as hoped, the first step is usually to carry out some simple fertility investigations. These tests are designed to look at the main factors needed for natural conception and to guide us on the best next steps. They are not only about finding problems, but also about providing reassurance and a clearer picture of your fertility health.
The initial checks usually focus on whether you are releasing eggs regularly, whether the fallopian tubes are open, whether the womb is healthy, and the number and quality of sperm. The exact tests offered depend on your age, medical history, and personal circumstances. Starting with these basic investigations helps us plan care that is safe, timely, and tailored to you
Blood tests can confirm whether your ovaries are releasing eggs regularly.
This is usually done with a blood test, taken about a week before your period is due.
It measures a hormone called progesterone, which rises if you have released an egg that month.
Blood tests such as AMH (anti-Müllerian hormone) or FSH (follicle-stimulating hormone) give an idea of how many eggs are left in your ovaries. An ultrasound scan can also count the small follicles (egg sacs) to give a picture of your egg reserve.
An ultrasound scan uses sound waves to create a picture of the uterus. It can show whether the lining of the womb is healthy and whether there are any changes, such as fibroids or polyps, that could affect pregnancy.
This can be done with a special ultrasound scan using fluid (called a HyCoSy) or an X-ray test with dye (called an HSG). Both check whether the tubes are open for the egg and sperm to meet.
The man provides a semen sample, which is looked at in the laboratory. The test measures how many sperm there are, how well they move, and their shape.
