Ovulation Induction (OI) or controlled ovarian hyperstimulation (OHS) is a treatment option used to induce ovulation in women. OI is usually the initial step in fertility treatment due to its lower costs.
The most basic form of OI is using a pill taking by mouth usually Letrozole or Clomid. These medications are taken for 5 days then you are scheduled for an ultrasound to see how your ovaries have responded. Based off of the results of the ultrasound you will either be scheduled for a follow up ultrasound or you will be ready the “trigger shot.”
What is a trigger shot? A trigger shot is an injection of Human chorionic gonadotropin (hCG) in the muscle that causes you to ovulate. After this shot you will have either timed intercourse or Intrauterine Insemination (IUI.). IUI involves placing specially washed and prepared sperm directly into the uterus. The male partner provides semen at our laboratory or we work with sperm banks if needed.
Stimulated IUI using injectable medications is often the next treatment step after failed OI treatment using oral medications. The monitoring and treatment is the same as above.
