Ive not done a medicated cycle before but ever asked my doctor on the difference. It is basically a timed cycle for better control. They use estrogen and progesterone (usually injection) to prime the lining and help it to thicken and be more receptive. Sometimes, they use a HcG injection to cause ovulation to occur. My doctor ever said that success rate is comparable for both and some people might benefit from a medicated cycle more. For instance, ppl with irregular periods or PCOS.
Icic, i didnt taken any progynova before, hopefully wont have any side effects, . i took letrozole for my natural FET, will cause me to have bad headache.(a) was given progynova oral tabs for FET and utrogestan vaginal tabs prior to days before transfer
(b) medicated is more controlled so less if hiccups and aborted cycles unless linking still does not make it despite medicine. Success rates would vary because not only it depends on cycle, it also depends on embryo, lining and a myriad of other factors
(c) start of cycle progynova tabs, depending on days before transfer start on utrogestan tabs to prime lining (e.g. 5 day embryo means 5 days before transfer to insert), no need to track ovulation
thanks all, i guess i have to try the medicated FET next month.
