Ovulation Induction

Ovulation Induction

Ovulation induction (OI) is a treatment option for women with irregular cycles, or an imbalance in their reproductive hormones.  Medication is used to stimulate the growth of ovarian follicles, and also to trigger/time release of the egg/s.   Intercourse in the days up to the time of ovulation will give a couple the best chance of pregnancy within each cycle.

The aim of monitoring during an OI cycle is to determine the day of peak fertility (ovulation).  This is often referred to as ‘cycle tracking’.  It will involve one or more vaginal ultrasounds to assess the follicle growth in your natural cycle.  ‘Seratec’ a urinary home testing kit is used to detect the commencement of ovulation.  Blood tests to check hormone levels may also be required during the cycle.

Ovulation Induction Treatment Timeline

Day 1 Please telephone the Patient Liaison Administrators on the first day of your period (full flow of bleed).  This is called Day 1.  The Patient Liaison Administrators will transfer you to the nurses who will then review the doctor’s treatment recommendations, and plan your cycle with you.
Day 3 If you have been prescribed FSH injections, you will be required to start the daily injections on Day 3 of your cycle.  Your injections should be administered at the same time each day.  Once you have informed the nurse of Day 1, cycle tracking will commence.  The nurse will advise you of the date of your first ultrasound appointment.
Day 3 - 5 If you require Clomiphene tablets to stimulate follicular growth, they will usually start early in your cycle (between day 3 and 5) for the duration of 5 days.  The aim of taking Clomiphene is to stimulate the release of FSH, which will cause ovarian follicles to grow.
Day 11 To monitor your response to the medication, you will have an ultrasound on day 11 of the cycle (and thereafter depending on the results).  The vaginal ultrasound measures the thickness of the lining of the uterus (the endometrial lining) as well as the size and number of follicles on both ovaries.  
Onwards You may be asked to commence Seratec after your first vaginal ultrasound.  Seratec detects your body’s Luteinizing Hormone (LH) surge, which generally happens 24 hours before ovulation.
Approximately Day 11 When the monitoring suggests the ovaries (and eggs) are ready, a final ‘trigger’ injection of hCG will result in ovulation.
Timing of intercourse The ideal time for intercourse is before and up to the time of ovulation.  Intercourse may commence any time after the 1st scan, and it is advised that a couple have frequent intercourse (every couple of days) from the time a large follicle (>16mm) is identified.
Pregnancy Test If you do not have a period within 16 days after ovulation a pregnancy blood test should be completed.  Please contact the nurses, who will organise this blood test for you.
