These tests measure the level of follicle stimulating hormone (FSH) and estrogen on the second day of your menses period. The test values give us an indication of ‘ovarian reserve’, in other words, how hard your pituitary gland in your brain has to work to stimulate your ovaries to ovulate. These values give us a rough idea to determine what IVF protocol to choose, how much hormone injection (FSH dose) may be required for stimulation and an insight into the potential success rates of IVF. Some centres may not accept a woman if her blood FSH level is > 11 mIU/mL.
