How does timed intercourse work?
When your doctor prescribes this treatment, our centre sets a start date with you based on your cycle.
- On day 1 of your cycle, you must phone Brussels IVF to schedule an appointment for a blood test and an ultrasound. This will take place around day 10-12 of your cycle.
If stimulation medication (tablets or injections) is used, you must take it as prescribed.
- At the scheduled time of your check-up, you have a blood test and ultrasound done to monitor how your cycle is evolving and/or how your body is responding to the medication.
- That same day, you will get the results and instructions from our Daily Monitoring (DM) team.
We use blood tests to monitor when an LH peak occurs and when you will ovulate.
We use ultrasounds to monitor the growth of your follicles. We strive for a mature follicle (diameter > 17 mm).
- An LH surge in your blood may indicate that ovulation has already started. Sometimes, you may also be asked to inject a dose of hCG (trigger) to trigger ovulation. DM will give you instructions.
- You should then have sexual intercourse that evening, as well as the following evening.
- Two weeks later, you must have another blood test to check the result of the treatment.
What is ‘day 1’ of my cycle in ART treatment?
Day 1 of your cycle is the first day of your period, meaning the first day of bright red menstrual bleeding or full flow before noon.
Did you only get your period after noon, or did the blood only turn bright red during the day? Then the next day counts as day 1.
How many blood tests and ultrasounds do I need as part of my treatment?
You need to make an appointment for blood tests and ultrasounds at Brussels IVF.
Blood tests are done:
– on weekdays: 7 am. – 8 pm.
– on weekends and public holidays: 7:30:00 – 4 pm.
If the result needs to be known the same day, the blood test should be done before 12 noon on a weekday and before 10 am on weekends and public holidays.
An ultrasound can be scheduled:
– on weekdays: in the morning and evening
– on weekends and public holidays: only in the morning
During your treatment, hormonal analysis and vaginal ultrasounds can also be done closer to home. You can get your GP or your gynaecologist to do the ultrasound and blood test and have the analysis done by an external laboratory. In that case, the result must be delivered to our DM by 1pm by e-mail.
Please note: we charge an administrative fee for the processing of external results.
