The prospect of daily injections can be overwhelming. While injections are a necessary part of IVF treatment, we have designed our medication schedules and injection type to minimize discomfort and stress; and our nurses carefully instruct and support every patient throughout this process. Medications that once had to be injected into the muscle have been replaced by medications given as a small injection under the skin (subcutaneous). Such injections are most commonly taken over a 10-12 day period, followed by one intramuscular injection of hCG, a hormone that triggers ovulation at the conclusion of the stimulation cycle. The hCG injection, previously only available in an intramuscular form, is now available in a subcutaneous form (Ovidrel) for patients that wish to avoid intramuscular injection. Although the recombinant subcutaneous form of hCG in Ovidrel has not been around as long as intramuscular hCG, all indications are that it is just as effective.
After egg retrieval, patients are given a progesterone hormone supplement in order to prepare the lining of the uterus for the embryo transfer. For most patients, progesterone may be taken in a vaginal tablet or vaginal suppository form rather than an injection. In this way, injections may be avoided entirely during the second half of the IVF cycle. Progesterone vaginal tablets and suppositories have been proven to be as effective as progesterone injections.
