The Lupron Protocol (Luteal Phase Start)
Starting around three weeks after ovulation, Lupron (leuprolide acetate) prevents eggs from being released too soon. The small daily injections - usually in the abdomen or thigh - help your care team control the timing of egg maturation.
One fertility endocrinologist explains that “Lupron lets us synchronize your cycle perfectly, that precision is what gives us such consistent outcomes.”
The Antagonist Protocol
For patients who need fewer injections or have a higher risk of overstimulation, medications like Ganirelix or Cetrotide can block the body’s natural LH surge mid-cycle. This option starts later - around day six of stimulation - and offers a shorter, more flexible approach.
FSH Medications (Follicle-Stimulating Hormones)
These are the engine of the IVF cycle. Medications like Follistim®, Gonal-F®, Menopur®, and Bravelle® contain hormones that directly stimulate follicle growth. As your nurse prepares and administers your medications, they’ll guide you through each step — from careful mixing and precise measuring to gentle injection — ensuring you feel informed, confident, and completely supported throughout the process.
