Minimal Stimulation IVF differs from traditional IVF in the type and amount of fertility medications used to stimulate the growth of egg follicles.
Traditional IVF uses injections of the hormone FSH (follicle stimulating hormone) to stimulate the growth of multiple eggs which are then harvested from the ovary and fertilized in the laboratory (in-vitro fertilization) before being transferred to the uterus as embryos.
With Mini Stim IVF, a tablet form of fertility medication called clomiphene citrate is taken for 5 days to increase the natural production of FSH in order to recruit multiple egg follicles. Hormonal injections may be used for a few days but at much lower doses than used in traditional IVF.
Although fewer eggs are recruited with Mini Stim IVF, the ones that do grow are believed to be highest in quality. Other benefits include less injections, shorter treatment times and lower cost. Mini Stim IVF is a good alternative for women who respond poorly to traditional hormonal stimulation or have failed traditional IVF.
