Ovulation and fertility: What happens at an initial assessment?

The timing of assessment is decided individually

A delay in becoming pregnant does not, on its own, show at which stage a problem lies. Ovulation, the fallopian tubes, the womb and sperm characteristics are assessed together. In general, investigation is considered when pregnancy has not occurred after one year of regular unprotected intercourse under the age of 35, or after six months at 35 and over. Over the age of forty, if periods are very irregular or if there is a known reproductive health problem, an earlier consultation may be appropriate. These time frames do not replace an individual history, and a first consultation does not necessarily mean that treatment will begin.

A menstrual calendar is useful but does not make a diagnosis on its own

The start dates of periods, the length of bleeding and the differences between cycles provide information about ovulation. Regular periods are usually consistent with ovulation; when there is irregularity, the cause may need to be investigated. Predictions from phone apps and home ovulation tests do not measure the whole reproductive process. The timing of any hormone tests considered necessary is chosen according to the characteristics of the cycle. For example, it may not be appropriate to measure progesterone on the same calendar day for everyone. Results are interpreted together with symptoms and other findings. A particular day being marked in an app is not definitive proof that ovulation happened on that day.

The investigation covers both partners

At the first consultation, previous pregnancies, past operations and infections, medicines being taken, other medical conditions and any difficulties with sexual intercourse may be discussed. Assessment of the partner providing the sperm is also part of the initial process; a semen analysis is requested when needed. Ultrasound and tests that assess whether the tubes are open are planned according to the history. Ovarian reserve tests such as AMH can help with some treatment decisions, but on their own they do not definitively show the chance of natural conception. A low result should not be interpreted as meaning that pregnancy cannot occur. Not everyone needs to have every test.

Preparing for the consultation makes decisions easier

Preparing period records, previous test results and a list of the medicines being taken, including non-prescription products, makes the consultation more productive. How long pregnancy has been attempted and any results obtained before are also important. You can discuss with the doctor which question is being answered, how a test result would change the next step and when the situation will be reassessed. If the process is creating an emotional burden, sharing this is part of care. At the end of the investigation a cause may be found, but there may also be situations that cannot be explained with the available tests; follow-up and treatment options are considered in line with the findings and preferences. Setting aside time for questions is also important.
