The Aim of Next Treatment



Decrease the stimulation

Clomid, Letrozole, HRT-OPU Method, Complete Natural Methods

Ordinarily stimulation will be decreased. However, there are cases in which the AMH and number of collected oocytes do not always correlate, so there are also times when the stimulation method will be selected to match the needs of that person's condition. Another way is to take the method combined with the ovulation induction in HRT-OPU Method that decreases FSH and expects follicle development.
