Depending on the history of the patient, they may start with hormone medication such as clomid or femarra, which can often have side effects that acupuncture can help with.
Next step might be Intracervical insemination (ICI) or intrauterine insemination (IUI). If this is unsuccessful they may choose to move forward with Invitro insemination (IVF) which requires 2 phases. The first phase is the stimulation phase, where they are given fertility drugs like follistim and menopure to stimulate the body to produce many eggs.
Acupuncture can help increase the follicle count, egg quality, and also aid with the side effects of hormone medications. After the retrieval, they see how many of those eggs successfully become embryos and then they usually freeze them until they are ready to for 2nd phase; which is the embryo transfer.
Depending on how many follicles made to the 5th day of embryonic development is the number of chances you have, before another stimulation cycle may be needed. Acupuncture can increase your odds to nearly 40-50% per cycle. Odds of success are dependant on age, egg quality, health history. The odds of success increase slightly with each step they take, ICI to IUI to IVF.
