At Coastal Fertility Specialists the second step in the Ovulation Induction and Intrauterine Insemination (OI/IUI) process is the ovarian stimulation. The goal is to use low doses of medications to help create 2 to 4 mature eggs. Any more than 4 eggs significantly increases the risk of a multiple pregnancy without improving the pregnancy rate.
The physicians at Coastal Fertility Specialists generally start the ovulation induction process with a combination of oral medications such as letrozole and combine it with injectable gonadotripins to help increase egg quality.
The stimulation is monitored through ultrasounds performed every 3 to 4 days along with blood hormone measurements including estradiol and progesterone. Once the majority of the follicles (pockets of fluid which typically contain eggs) are in the 16 to 20mm size ovulation is triggered with HCG and the intrauterine insemination is performed 24 to 40 hours later.
