PROTOKOL AGONIS D1
This protocol is usually done in women who have regular periods. A GnRH (gonadotrophin releasing hormone) agonist called Buserellin is started 7 days before the expected next menstrual cycle. In a woman who has a 28-day cycle it will fall on the 21st day of her previous menstrual cycle. 0.1 mls of buserellin are given in 2 divided doses 12 hours apart. You will be taught to self-administer this injection.

This injection is given until your next menses.

After about 10 days of this injection and you have had your menses, you will be seen in the clinic for an ultrasound and a blood test to ensue that you are downregulated. Down regulation means that your pituitary gland (located in the brain) is not producing any more FSH ( follicular stimulating hormone).

You have been downregulated if

  • your ovaries do not have any large follicles
  • your endometrium is thin
  • blood tests shows a low oestrogen, progesterone and LH (luteinizing hormone) level.
Once you are downregulated, you will be started on a second injection calles FSH (follicle stimulating hormone). Your doctor will decide on the type and amount of injection.

You are required to continue with the buserellin injection when you start your second injection.

Your dosage of buserellin will be reduced to 0.05mls taken 2 times a day 12 hours apart.

After about 5 days of the FSH injection, you will be seen in the clinic for a blood test and ultrasound. Based on the results, you will continue with the same dose or he may increase or reduce the dose.

You will continue the injection for another 3 or more days. You will be seen 1 or more times for an ultrasound and blood test.

When the follicles reach 16 to 18mm in diameter and the blood hormone level are considered good, then you will be given an injection called HCG. This injection is given to induce ovulation. It is given at night and the time of the injection will depend on the time of oocyte recovery. Usually oocyte recovery is performed 34 to 36 hours after the HCG injection.
