vaginal ultrasound. The doctor will review your ultrasound and blood work to
determine when you will return for more monitoring.
3. You will get portal instructions that afternoon to start the injectable gonadotropin
(Gonal-F or Follistim). The physician may also opt to have you take estrace.
4. The physician will review labs and continue monitoring to determine dominant
follicle and or endometrium of 7-8mm. This may be daily or every other day.
5. If ordered by your physician, the hCG trigger will occur with a dominant follicle of
at least 18mm and/or the beginning of an LH surge. If no hCG was ordered, then
an LH level > 10 will be considered a surge.
