Ovulation tracking and timed intercourse

Sometimes, addressing infertility can be as simple as timing sexual intercourse to coincide with when a woman is most fertile. This can be achieved by determining the time of ovulation (the release of an egg from the woman’s ovaries).

Our fertility specialists can help you pinpoint the time of ovulation through a number of different methods:

Menstrual cycle

For women who have a regular period, we can use the length of your cycle and the date of your last period to determine when you’ll next ovulate. Specifically, it’s the date 14 days prior to the first day of your period. If you have regular periods, feel free to try our ovulation calculator.

Changes in vaginal mucus

While not used as a stand-alone method, knowledge of the changes in vaginal mucus over the course of your cycle can help determine when you’re ovulating. Typically, vaginal mucus becomes thinner, clearer and stretchier at this time. It also increases in volume.

Measurement of hormones

Hormones called LH (luteinising hormone), FSH (follicle stimulating hormone), oestrogen and progesterone are responsible for a woman’s ovulation and menstrual cycle. By taking serial measurements of the levels of these hormones in your body, we can determine if and when you’re ovulating.


By performing serial ultrasounds, it is possible to observe changes in the ovaries that indicate the timing of egg release. Furthermore, we may also use this information to administer a trigger injection, which guarantees ovulation 38 hours afterward.

Once the date of ovulation is established, defining a woman’s most fertile period is straightforward. In the female reproductive tract, sperm can survive for up to 5 days – and once ovulation has occurred, an egg will be present for a maximum of 24 hours. This means there is a broad window, prior to and including the day of ovulation, during which a couple can get pregnant. The most fertile period during this time is in the 2 days preceding ovulation and the day of ovulation itself.
