Why is it important to have as many mature eggs as possible?
One of the main goals of IVF is to obtain as many mature eggs as safely as possible in order to maximize the chance of having a normal embryo for transfer. Unfortunately, as the quantity and quality of eggs produced in each cycle decline with the passage of time, the pursuit for a normal embryo becomes more and more difficult.
Is aggressive stimulation for resistant ovaries more effective?
There comes a point when aggressive stimulation for the resistant ovaries is no longer cost effective. For patients whose ovaries can only provide 5 or fewer eggs a cycle, a gentler stimulation protocol that uses the body’s natural reservoir of FSH (Follicle Stimulating Hormone) may be more sensible.
Can IVF be done with low ovarian reserve?
However, in women with extremely low ovarian reserve, a better choice may be to use the gentler stimulation of the Mini IVF cycle to accumulate embryos that can later be transferred to a more receptive uterus of a FET cycle. For these women, less stimulation can mean more embryos for a better chance of success.
