IVF treatment is tailored to your specific needs by your fertility specialist. Most patients who undergo IVF will be prescribed one of two main treatment protocols Long Down Regulation and Antagonist treatment cycles.

Long down regulation treatment is the process of suppressing a womans natural hormones before fertility medications.

Approximately 3 weeks after your period starts you will have a blood test and begin pre-IVF treatment [GnRH analogue] in the form of a Synarel nasal spray or Lucrin injection to control your natural hormones before the fertility medication starts.

About 12 days later another blood test will be taken to make sure your own hormones are low [or down regulated] and you will be instructed when to begin daily hormone Follicle Stimulating Hormone injections [Gonal-F or Puregon]. You will continue taking the Synarel or Lucrin throughout this time.

5 days after you begin FSH injections you will have a blood test and ultrasound of your ovaries.You will be monitored closely with blood tests and ultrasounds until you have an optimum number and size of developed follicles. Once you are ready will we advise when to have your hCG trigger injection and schedule your egg collection 36 hours later.

After egg collection you will use supplemental progesterone either as a vaginal gel, pessary or subcutaneous injections until your pregnancy test two weeks later.

Antagonist treatment uses injectable drugs called antagonists to prevent premature ovulation. It is the most commonly used treatment protocol because the shorter cycle makes it more convenient for patients and reduces the risk of hyper-stimulation.

Starting on the second day of your period you will have a blood test and providing all your hormone levels are low, you will be advised to begin Follicle Stimulating Hormone (FSH) injections [Gonal-F or Puregon] that day.

After four days of injections you start a second injection [Cetrotide or Orgalutron] to switch off your own hormones and prevent premature release of the eggs. 6-8 days after you begin FSH injections you will have a blood test and ultrasound of your ovaries. You will be monitored closely with blood tests and ultrasounds until you have an optimum number and size of developed follicles.

Once you are ready will we advise when to have your hCG trigger injection and schedule your egg collection 36 hours later After egg collection you will use supplemental progesterone either as a vaginal gel, pessary or subcutaneous injections until your pregnancy test two weeks later.
