What is a good estradiol level for IVF?

Estradiol levels are complex and depend on several factors. It's best to discuss your estradiol level with your fertility doctor, who can interpret the results in the context of your situation and provide personalized guidance. Estradiol is a hormone produced by the ovaries. It's monitored during ovarian stimulation to assess the development of the follicles. The target estradiol level depends on the number and size of the follicles.
