Sample calendar and schedule for an injectable gonadotropin fertility treatment cycle - "Injectables"
Page author Richard Sherbahn MD
These infertility treatment cycles are often referred to as controlled ovarian stimulation (or, hyperstimulation) cycles. Injectable FSH products are also referred to as HMG, human menopausal gonadotropins, or gonadotropins.
Brand names for these drugs (hormones) in the USA include Menopur, Bravelle, Follistim, Gonal-F, and Repronex.
This sample calendar shows the days medications are taken and approximate timing of the monitoring of ovarian stimulation and the intrauterine insemination (IUI) procedure.
Injectables are usually done in conjunction with IUI to get a better success rate, but can also be done with timed intercourse.
Menstrual period starts
blood and ultrasound
Day 3 of
Day 4 of
Blood and ultrasound
Day 7 of stimulation
Stimulation is done - HCG "trigger" shot given in evening
Day 8 of stimulation
Insemination, IUI - (or timed intercourse) in morning
Key to table:
Blood and ultrasound = blood test for hormone levels and transvaginal ultrasound to measure follicle development in ovaries
FSH = subcutaneous injection of a medication containing follicle stimulating hormone (FSH), which causes follicles containing eggs to develop in the ovaries.
HCG "trigger" shot = injection of a medication called HCG, which causes the eggs to complete the maturation process. This is taken only once in the cycle. Release of the eggs should occur about 36-46 hours after the shot.
- The duration of stimulation is usually about 8 days, but ranges from about 5 to 14 days.
