Hi, can an estrogen priming ( 5 days before my period )or taking hGh 8 weeks prior to stimulation and during stimulation cause slower growth of follicles? My forth stimulation protocol is the same as the previos three ( third one was 3 months ago, the first and second two years), but my follicles are not growing. I’m taking Gonal f and Menopur (from day 4.). They increased the dose of Gonal f, but still going nowhere, it’ s day 11 of stimulation. Thank you for your answer. Polona
